Hilti changed from Aluminium conrods to plastic years ago, The reason was when the Aluminium gave up the ghost it would punch a hole in the top housing too. With plastic it would break and get chewed up to save destroying the top housing as well. Cheaper in the long run. I repaired Hilti's for 12 years. Great machines to work on.

I love how we’ve gone from “sorry focus” to “ focus YOU...”

"Zero cheap-ass fuckery going on with this thing." ROFL, I want that on a T-shirt.

Ah HILTI... the choice of professionals that have to get into bank vaults overnight.

The plastic used in the con rod is a pretty effective steel replacement. Usually it comes from BASF or EMS (called Grivory). The lighter you make the con rod the less vibration you get and the lower the power requirement. I'm actually pretty impressed to see it in there.

For anyone interested, pre decimalisation in the UK, which occurred over a couple of years ending I believe in 1971, the British used the duodecimal system (which as a kid I heard as jewy decimal) based on base 12. The pound had 240 pennies and 240 pennies was 20 shillings a crown was 4 shillings a half crown 2 shillings, there were farthings (parts of a penny) threepences and sixpences. The smallest note when I was a toddler was a 10 shilling note, which disappeared in 1971 as well I think. So in today's money the old sixpence is 2.5 new pence. Things were called 'new' pence for ages, and without taking out a coin and shuffling through old 2ps I don't know when they stopped using that. We were pretty much forced by Brussels to drop our weights and measures in line with the rest of Europe, but its amazing how many still say a pound of sugar, a pound of potatoes a pint of milk or beer and we all still use miles per hour. We are all pleased if we are 6 foot high - mm is ok, they are useful. Never understood why we always used CC/litres here for engine displacement though - even pre decimalisation, in fact always?

I love your technical jargon

As far as I know the torque limiting clutch is not to protect the gear but to protect the user. That beast can break your arm if your drill gets stuck. Hilti also uses some electronics called atc in addition to the mechanical mechanism to stop the motor when the rpm changes weirdly.

The flame test seemed a lil wingnut, try the Vinegar Test. Five drips of white vinegar on a clean, bright spot, wait 93 milliseconds, bubbles=Magnesium, boring = Aluminium

PA is not Polyacryalate, PA is Polyamide and CF is not Glassfibre its Carbonfibre ! Greetings From Germany and I apologize for my butcherment of the English language :-)

Dude srsly ... clothing, weight, looks, opinions ... DO NOT ENGAGE! ABORT !!! ABORT !!!

casually throws in a small block chevy firing order

New sub...so truly enjoy your vids and wickedly great sense of humor! Love it. I worked for an air tool manufacturer back in the late 80's early 90's. ARO Corp. They were bought out by Inger-soild-and-ran. While my time there, I ran lathe and ID,OD grind operations and I have to say that our work was on par with this hammer drill you opened here. The workmanship was impressive just as in this tool. Bearing surfaces were held at +/- .0003 with run out and taper no greater than .0005. The finishes I ran were held to between 32 to 16 micro depending on part. I'm not sure if the quality is what it use to be but this tool reminded me of the work I use to be a part of. Thanks for the vid.

I used used Hilti drills for years professionally they are one tough machine and that clutch is to save the operator death by drill

"she's a skookum choocher" I lose it every time :')

CF = Carbon fiber GF = Glass fiber AF = Aramid fiber (Kevlar)

Firstly. Congratulations on the correct pronunciation of Aluminium. Secondly. We've had metric money since the 1970's! Although our system is fucked up. Our roads use miles and yards, beer and milk come by the pint. Although petrol is sold in litres. Babies are measured in pounds and ounces. But market sellers got in trouble for selling fruit and veg by the pound!

best tool reviews on youtube. my fav youtubber.

The "plastic conrod" is made that way on purpose, not to be cheap. They last a really long time. They are made out of plastic to prevent it from grenading the piston tube when it breaks and flying out of the tool like metal ones used to.

Hilti is not a german company..it sits in Lichtenstein :) The conrod is PA6CF20? Thats no glass reinforcement, thats carbon fibre. Awesome machining on the parts An midrange hammer drill like a Duss (They are a german company!) would also be an interesting victim or one of the smaller Makita hammer drills... ;) Keep on going!

As always this was a great review. And thanks a ton for mentioning my channel!

I love your passion for good work. It's so hard these days to find people who can actually appreciate true craftsmanship.

Yeah, your technical jargon (e.g. chooch, skookum, cuntstun tongueslide, et cetera), and your comedic genius, is one of the big reasons I watch your channel. Obviously, learning stuff is fun too, but if I had to just listen to some dude monotone his way through a overly technical video about something I don't understand, it wouldn't be near as fun. And yes, I do binge watch, and I'm running out way faster than you are pumping them out, so I have a feeling this is gonna end up like Game of Thrones; good fun while you have 5 seasons you can watch anytime you want, and real bad when you done goofed and watched them all in like a week... And yeah, the lingo is definitely rubbing off. People are gonna start wondering if I had a stroke or something. You know how when you order chinese food, and while it's ringing all you can think about is not saying; _"Herro, can I get rhe chrikin and brockorry preez?"_ Yeah, it's starting to get like that.

hi AvE just wanted to say a Guinea isnt used in the uk currency it hasnt been since 1971 before my time glad to say lol. pounds are easy like metric 10 or 100 of everything, 10mm 1cm 100cm 1 metre etc, 100 pence to a pound pretty simple really lol. its how its taught here in education, AF always found more awkward to use and work out because not the standard here so hardly ever used. everything is metric, apart from pipe fittings etc which are still in imperial as obviously it would be pretty hard to convert all of that over nothing would fit be a lot of leaks well i gather thats one of many reasons why it wouldnt make sense too. love your channel so entertaining and informative, love your sense of humour too and have learnt a lot over time watching, keep it up i'm from wales btw :D

half your vocabulary is foreign to me but i feel like it belongs there.

If you're worried about the battery when you have it apart; a good trick is to wrap all the batteries and wires in aluminum foil. Protects you from electrons because they bounce off the foil back into the wires to self-charge the battery.

The PA6 on the plastic is PolyAmide 6, more commonly known as Nylon 6, and I think you're right about the 35% glass fiber fill, it really ups the strength of the plastic considerably.

These tool reviews are absolutely excellent. I learn something new every time. I'm an electrical guy, by profession, so a lot of the mechanical details are new to me. I love learning this stuff, so thanks for sharing.

Had a HILTI drill for about 12 years used in industrial plant maint. I got it so crusty on the inside I had to open it up and clean all the crud out of it. I couldn't kill it so when I retired I bought another new set of batteries and gave it to my son 3 years ago and he uses it daily in his job. Best made tool I ever had by far.

hi Ave. as a hilti repair tech I would be I interested to see a review on the hilti te 76

Im a big fan of Hilti tools. As an end user I always knew they were the best you could buy but just by feel and performance. Looking at the precision this tools is built to its now easy to know why they are great tools. Great video AvE, keep choochin!

The Simpson's writers must watch your vids. Last Sunday's episode had a self-help group sitting in a circle and one dude talking pops out "Chooch". LMAO!

When a woman asks you what you think about her new clothes, she doesn't actually want your opion, she just wants confirmation on what she thinks of it. -_- Well then, time to get back to drinkin. CHEERS.

can you compare a cheap bosch machine ( green) and a professional one ( blue)? aaand yeah btw hilti isn't german, it's from liechtenstein.

My company got sold on one of these with the Dust Recovery System. This thing is amazing. It takes whatever you throw at it and it doesn't break. I'd be willing to drop my Milwaukee M18 for one of these even at almost triple the price tag.

I have no idea what is going on here, it's 5:30am and I just can't stop watching this.

Bearings are installed under temperature of the liquid nitrogen -209 celsius for axe and 50 celsius for bearing. After a while come both temperatures to environment 25 celsius and this connection will be fixed.

I learn so much from these videos. I learn mechanics, quality control, and to speak Canadian.

That retaining pin being a softer metal is intentional. They knew that little slug of metal would not keep tight tolerances, so they stuck something softer in there than would do damage to the parts it is retaining. You see a lot of things using brass for that. That is just another small detail they did not overlook. Its soft so it can safely bounce and bang around without hurting anything. If it was harder, all that damage you see would be on the gears instead of not even mattering on the pin :P And that plastic is carbon fiber reinforced nylon. Tough and not cheap stuff. Not even deserving of the title 'plastic' really.

Better then anything on TV. Keep up the good work!

Couple years back I did a Streibig Optisaw install at a Home Depot and was using a bosch hammer to drill the floors for the concrete anchors, the guy at the tool rental had gotten some of these brand new hiltis cordless and I used it , was a real killer worked preety damn fast.

at 22:30 the cap was off that sharpie for ever. Its rather painful to watch and makes me cringe. don't let sharpies die when they don't need to.

This is so entertaining and i have no idea what half of the stuff even is.

"ZERO cheap ass fuckery going on here, HOLY." That's some funny shit right there.

That torque limiting clutch has provided so much laughter for myself. Guys coming to me with Hilti claiming that it doesn't work when they push it like hell when drilling :D Just ending up with a hole which isn't round and the bit is stuck.

Nicely trolled. The British have decimal currency and are almost 100% metric. Quite a while already. The only thing not metric are beer, milk and newborns and the highway code.

"Plastic (conrod), thumbs down!" What would you do instead? Put some bearings in there? (lol?). I think the plastic should get a thumbs up here. Great video, had to pounce on this though.

Goddammit I love every aspect of ur videos... The jargon, the idea, every fucking thing you do pleases my ears and eyes...

Yes! I've been waiting for a HILTI tear down. I've used two of their rotary hammer drills, one of them being this one. They are just phenomenal. They don't even compare. The battery themselves last forever too. Not just per charge but over the life of the tool. They sink right into the hardest of concrete like freakin butter.

I'm a Brit machinist and like nothing better than to watch you disassemble all sorts of gear and listen to you work lingo which to us is a wtf does he mean moments but other than that I agree with you about the old currency values and names. I won't go into it as you will have a big WTF is he ranting on a bout moment but if you ever get the chance to listen to a Scottish engineer work slang (lingo) you will never diss your English bros. by the way plse try and get hold of a old style planetary automatic car gear box because those things are PFM (Pure F-ing Magic)

Hilti!!! Bought over 50 of them over the years when I owned a security company. The expense in the Bits. Gave me the drills free, I spent so much on bits.

i would love to see this beast up against its most recent replacement (hint to hilti send him your latest model or are you yella?) i suppose the lure of the orient may have swallowed up even the hilti engineers at some point as it has with most tool manufacturers, That unexpected plastic part must have passed some sort of 'fit-for-purpose test' given the jaw dropping attention to detail on the metallic items. Keep the vids coming they are the Festool of engineering vids :)

Hey man i love your vids.. watch all of them.. my wife sometimes finds me passed out in the man cave with your channel still playing. Please do the Hilti BX3 battery nail gun.. it looks like a laser blaster out of star trek. For $3000 i would assume its like the Ferrari of all nail guns.

Addicted! It's good the know that the knowledge of the species is being archived on the KZfaq!

you sir are AWESOME! would love to hang out and have a dram and a laugh! loving the lingo!

5:40 in the morning and after discovering your channel I've been watching for hours. If I couldn't sleep before, I absolutely won't sleep now until I watch your entire catalog. Thank you for teaching me more in three hours then I can usually learn in month watching youtube. As you say "inquiring minds NEED to know". Cheers!

Thanks for another tear down video this videos are really nice. Its nice to see someone who isn't always afraid to take the thing about just to see the guts and sometimes get her back up and running.

That dude doing the forging in the intermission has got big ole brass balls never seen anyone operate a hammer forge in a t-shirt no nanny state in that shop

Have used that a lot, never got any problems. Intrested to see whats in there. Cant wait part 2

The 'plastic' connecting rod on the pneumatic hammer is actually plastic by design. 1) it is self lubricating 2) it doesn't suffer metal fatigue 3) it is designed to break when there's a certain amount of stress (such as when the cylinder is stuck, rather than have the more expensive parts break. And as you say yourself later in the vid, manufacturers want to have 'predictable' times before something breaks, and plastic parts 'under load' are the idea way to do that, plastics will invariably harden and become brittle over time. (sucks, but hey, the manufacturer has a wfe and kids too :-))

I worked with some guys that could still kill a Hilti. Not completely though, they would always make it back from Hilti repair center.

Just because a gear is machined/ground/hobbed or broached doesn't mean it isn't powdered metal. PM parts can be forged as finished or"near net shape" depending on tolerance requirements of the finished part. If they are near net shape, they undergo machining to finish them. Every surface, a single surface or any combination in between may be machined after forging.

Interesting comments. I wanted to say, as has probably already been said somewhere in the 423 comments. What he said in my understanding of Kneipe Deutsch was "Factory exit closed" as in the Autobahn exit for the Factory was closed. Thus not boding well for the factory mentioned in the video. As far as the fight between metric and imperial measure. Many moons ago i learned that it is not about the measure at hand, just the calculations that can be derived from them. I could make up a standard unit of measure for any given situation and do the same math in much the same manner. It's just the values of the units not the units themselves that is important. So i'm down with micro inches, micometers and the standard fractions of a pixie fart. But, i digress. I like Imperial, just 'cause it irks people and is slightly amusing that we as Americans are using an Imperial anything. Good show, off to part 2.

I have watched 20 or 30 of your videos. I have picked up here and there when you talk about things to guess what your age might be. I am also guessing you are a millwright based in the mining industry. From what I can tell you are younger than me by at least a decade. I consider myself pretty knowledgeable on many topics. I am also a person that will try and tear stuff apart and fix it when it breaks and I collect certain broken things for donor parts. However your range of knowledge of such a vast range of topics blows me away. Knowing what things are made of by looking at part numbers. Looking at a bearing and knowing where it was made and if the company still exists. Marketing tools (the graph you drew in this episode) and the kickbacks (another episode). Lubricants and being able to tell what they are by how it sticks to your fingers. Seeing marks on a gear and knowing if it was forged or cut with tools. You sir, are pretty incredible, you must have hung around in a shop of some kind as soon as you were able to stand up and pee. I do have a question for you tho', did your dad or grandfather get you started by teaching you about machines at a young age then you started building things when you were able to handle the tools? Keep up the great videos, they are interesting and sometimes quite funny. Cheers eh?

connecting rod is almost always plastic. cause if it breaks...it won't do any damage to other parts. i'm a makita specialist btw. hilti is at the top. fein and festool also.

PA6 is based on Caprolactam (CPL) and is an organic compound (CH2)5C(O)NH. PA66 uses Hexamethylendiamin (HMD) and Adipinacid. It is different how they are produced, but they have similar properties: The melting point of PA66 is a little bit higher and it takes less oil and water. Mainly this is the reason why we use it in automotive operations, where oil and water is a problem for plastics. For tools it isn't an issue, so that's why you see PA6 often there. Yes, GF35 means that 35% of the material is glas fibre.

I always felt hilti was over priced and a lot of hype until I used them first hand. I had an 18 volt cordless Dewalt hammer drill and a 12 volt non hammer drill hilti I used them for drilling 12 to 24 inch 1/2 inch holes in concrete. The 12 volt hilti would out run the Dewalt every time. I even snapped a few of the bits off using the hilti. All the Dewalt would do was stall the chuck. And if you were not careful the hilti would very easily snap your arm if it bound up. They really do make some darn good power tools imo. And this is not meant as a bash on Dewalt, I feel they are still darn good tools for most people but when you need something more hilti is where it's at but it's not coming cheap.

yea same i learn so much from watching your vids ! could you make a vid on how to read plastic stamps

I got a new hilti 250v power drill in the 70s it ran for 25 years with only 2 breakdowns in hard regular use then stopped working Hilti wanted to sell me an exchange for 3000 gigles witch would not take any of my old drill bits "sds not sds+" so I sent it to my brother in Hungary & he had it fixed there for a six pack ! Its still running well o! I am British & live & work in France so I comprend sterling & inches, tea bags & metric. the hilti & I work a little slower now Grrreat vids

Have you done/can you do any IR tools? Awesome work you are doing here. Thank you.

17:30 Wouldn't CF20 mean 20% carbon fiber?

at minute 21, you shed some serious insight into marketing that bears on the current state of tools in construction ( my specialty ) and in general. You're dig on Milwaukee is well deserved - I have a 30 year old 1/2" drill that will not die, but there current battery tool crap doesn't last even one year with moderate use. The same could be said for Skilsaw , Dewalt - they still make one of the best chop saws tho). On the positive side, Hilti has always made an impression on me for not just quality construction, but they actually do the job better than anything else...their rotohammers are in a class by themselves. Love the manic chatter...do you have to go in every once in a while for a tune up?

You are a genius at explaining this in easy to understand term, including bonus on defacto tool industry profiting tactics.

I have had a few Hilti and used them hard - they never needed to go to the shop - they are just solid performers when combined with Hilti brand drills.

"you don't want any crib deaths over here" i'm fucking crying!!LMAO

I'm running out of content to watch. this channel is teaching kids more about shop class than the teachers ever did. well done good sir.

I kept hearing about Festools and I couldn't remember where I'd seen the name, but then it hit me. We had these disk grinders for wood on my last school, that we'd use 3 times a year at best. Those all had Festool vacuumcleaners as dust suckers. And we always wondered why there was never any money left for decent soap... Anyway, enjoyable vidya once again!

Man, when ever I have a shitty day, or just need a good laugh and want to learn some cool stuff, I enjoy watching your videos on choocher disassembly

Just discovered your channel and I must say I love your videos! Work for a plumbing company here in Switzerland and am fortunate enough to have a boss who only insists on HILTI tools and machines. Definitely not cheap to replace, as the TE 6 belonging to my colleague was pinched on site last month...

If you were still wondering, a standard amount of tea is 240ml, which comes out to 8.47 fl oz. Because fl oz is measure of volume, we need to convert that to it's weight of water. Which is about 231.6 grams. And 231.6 g comes out to be 7.44 Troy ounces. And I converted the ml to fl oz just because I can.

I have a hilti hammer drill that's as old as my granny and has seen some seripus shit in its lifetime and still eats through rock like a crackhead. Hilti is the pinnacle of commercial toolmaking.

Hi AvE, This is my second visit to your channel, and I like some of what I hear, however, please note: Just because it says it is "Made in Germany" … UK Poland or wherever does not mean it is! Especially with something that has such a wondrous variety of ‘bits and bobs’, several metals, plastic, washer of indeterminate origin etc … As your Loupe showed all parts no matter what they are being used for in this or ANY ‘motor driven tool’ can and almost certainly does have bits and pieces delivered to an ‘Assembly Station’ from around the World, and it could be the far East or Germany or the USA or the UK, it does not need every little item to be ‘Made’ in the so called Country of Origin. Did you realise I can’t recall them now but several major tools and or gearing and cases can be ‘assembled only’ in the original country and that is good enough for the EU to say "Yes of course you can stick a Made in UK on it. That is a terrible situation, but it is the owner/managers of these major tool and or car makers that get stuff made as you know in Taiwan or China because labour is cheap, but the company with its name on an item still charge the same or more and that seem like a huge ‘swindling deal’ to me, they give a spec give or take whatever the spec be to a Chinese company that know-one knows, and it might well be happening to just about every engineered item on the planet. Why? - Because the owner/managers are greedy bastards thats why. I hope you get my drift? Sorry for the lengthy rant but a case in point in a Vacuum maker that has those ’swirly’ vortices in their machines moves from the UK to assemble and make all the bits of their machines in either Taiwan or China, and instead of the price coming down as you might expect, in 6 years the costs have almost doubled. That company who I won’t mention, in run and owned by the same person and every year they made a 10’s of millions pounds profit by assembling the machines in the UK, but Mr greedy put 500 workers out of a job and shifted his whole business to the far East, greedy is the answer to my mind at least, why else does virtually everything get made in the far East now, because of greed. But remember the engineering specification is given plus and minus a size so blame the greedy bosses for the uncaring way they run their business’, not the Far East factories who are only going on spec.’ Oh BTW, no one moans about any electronics ones and or TV do they, and that is because those company’s like Apple for instance give the makers and builders such a high spec’ to follow year on year it DOES get better and stays better. If the same was done in the machine engineering side of machine tools etc and the saving passed on the USA and the UK would not be heading for a slump. Take care and I will sub you sir. mrbluenun

hope you know your enthusiasm is contagious

I picked up a Hilti SIW 22T-A impact wrench over a year ago for around a hundred bucks used. It is definitely a marvel and a joy to use and has never failed me once, Its even better when their customer service is not in India but damn I wish their batteries were cheaper.

we use hilti 24/7 over 10 years now , all day abuse 10 years straight, TE-7C solid as tank, sealings leak once every 2 years, but gearbox, electronics etc. never been touched. we have about 7 of them, never crapped out on me.

"Just gotta repair the repair" Right in the feels

Glad to have found an entertaining and down to earth channel with content I enjoy. Thank you for your time and effort put into the videos.

anyone else get the tree fitty firing order?

I've had a Hilti cordless hammer drill/recip saw combo for 10 yrs and I beat the balls off of it. Never had an issue and I use it everyday.

We dropped one of these things 25 metres off a viaduct into a shallow river that was in flood. It was in there 4 days until the river went down and we could wade in to get it out. dried the batteries on a radiator knocked the gravel out of the case. Fired up first time never missed a beat.

+1 for unrelated but cool intermission

I liked for the "How many pennies to the pound? How many pence in a guinea, in a pound? How many troy ounces sterling silver in a cup of tea?"

The life wisdom I learn on a tool channel....

AvE: When you talk about Festool and their attempt at a midbudget brand, you talk about Protool. This was thought to asses a different clientel of customers and be cheaper in production, but it turned out they still where way better than the competition and also cheaper. If anyone buys a Protool machine today, you have the major advantage of still getting service from Festool (and parts) but the stuff is unbeliebably cheap for the quality since it is officially EoP (end of production). There is one ebay shop in Germany that constantly sells Protool machines for maybe 40-50% the price of a Festool product (so it can actually be the same price as many other brands).

I think by 5:40, the pants were coming off, lol. Impressively constructed piece.

this is the best and most informative review of anything I have ever seen. Good job man I really enjoyed this, and am definetly going to be checking out your other videos. Keep em coming

My buddy has a Hilti hammer drill and I love it!

Late to this obviously, but wanted to discuss manufacturing costs. Many midrange brands are under the same umbrella, Milwaukee/Ridgid/Ryobi and BlacknDecker/Dewalt/and a few others are the same. Their costs can be cut down by making these items in large quantities and by reducing downtime in their large factories where tooling and equipment costs are shared. The batteries are also very high profit items with a finite lifespan which is why there’s incentive to lock users into certain groups of tools that share battery types. IMO, they’d be better suited to make fewer tools, but make them better; and then build brand reputation like Honda has. They could focus on fewer, higher quality parts and build loyalty through both performance and longevity. Better longterm business outlook. People may not need as many replacement tools, but they will need other tools and items your brand can carry.

I just found your channel yesterday and I barely could stop watching. It´s so interesting and educational, but foremost you´re hilarious! You are already on my top 10 KZfaq-list and I just can´t stop laughing.

I would love to see you do a side-by-side teardown of two similar tools - one from Dewalt, Mikita, Bosch, etc, the other from Festool. I'm not convinced Festool is really any better or in the Hilti category. The Festool drills are particularly suspect to me.
