This is a fantastic demonstration of how hammer drills and rotary hammer drills work. Thanks for sharing.

The advantage is greatest in rough concrete with large chunks of aggregate. When a normal drill hits a stone it can't break through it gets stuck whereas an SDS can go right through no matter if it hits a chunk of rock.

Great video! Just remember to never push hard or put much weight behind a hammer drill, its the movement that does the work, all you need to do is to add that slight force to activate the hammer function

There is an advantage to using a simple hammer drill to an electro pneumatic (SDS) one in some scenarios. Let's say you're drilling through ceramic tiles (e.g. a bathroom wall). Ideally you would drill through the ceramic part using only a rotary action and a dedicated ceramic bit with carbide or diamond crown bit. Then you switch to hammer drilling when reaching concrete. No matter how careful you are, because the SDS bit wobbles around, you have a great chance of denting the glaze around the hole. I have a Makita SDS drill and I know what I'm talking about, it is just too powerful for such a task. So a regular hammer drill with a regular chuck and limited motion is better for such situations.

ONLY NOW I KNOW, AFTER COUNTLESS YEARS IVE BEEN LOOKING FOR SUCH REVIEW....TQ SO MUCH :)

Thank you, very informative

Good video of combi-drillhammer vs a rotaty SDS drillhammer, thx.

Fantastic Video and great explanation.

Looks to be working fine for just a few holes around the house

That cliffhanger got me to this video

I've got the 481zk. It drills well

Perfect with "anti-vibration damper'

its a no context SDS for the win All day every day

do the flip flops come with charger n case or are they skin only, plus will my old battery fit them

I think the best combination is get 1 rotary drill 1 driver drill

Thanks mate, very much appreciated. Rotary drill is the go for me as a result of your vid.

Is there a difference in the quality of the hole ? Does one drill a smoother hole over the other ?

Can you do a comparison video with the sub compact brushless hammer drill (xph11)?

we all know that a sds is better than a combi drill but that Makita combi you have there is the highest torque drill they do, and if you only want to put a few shelves up or fix a toilet pan to a concrete floor etc the combi drill works just fine that's what its made to do small diameter holes 5 6 7 mm sds for your more rugged work

Thanks

Was STS plus a copy of the original Hilti? cause the very first Rotary Hummer drill i used was a Hilti TE17 back in the 70s n I was totally shocked at how Amazing it was next to he drills we where using them days, it was also a French drill called Spit very similar to STS but only one grove was holding instead of the usual 2 on the Bosch STS system n still for me by far the best rotary hammer drill bits are the Hilti ones they go for ever good video brings back memories for old boys like me good old days lol cheers

So rotary hummer , the distance bit travel all same right ? Because its depend on the bit it self

Thanks man

Thanks for the vid. Shout out to the flip flops.

いい比較👍

Do the sds plus have small bits like a 3/16? I need the extra power and speed to drill several holes for certain jobs..

Alot of people dont know this but on those Makita hammer drills, when you tighten the chuck on the bit you can take it back 1 single click and it will lock the chuck so the bits will never fall out.

How about 18-Volt LXT Lithium-Ion Brushless Cordless Hybrid 4-Function Impact Hammer Driver Drill?

I got this hammer drill just 2 days and drilled a few 8mm holes with it in concrete and the damn thing wont come off hammer mode, the ring is just stuck there. I think im just very unlucky and going to return it ofcourse. Has anyone experienced something like this with any makita hammerdrill?

Spin you right round baby right round

Can you use the gtx impact driver also for concrete holes here and there arround the house? Or need a hammer drill gtx line version? Asking as i have the impact driver recently.

It feels like I've wasted my money on a bosch cordless hammer drill ...

Thanks but tell us internal mechanical difference between Hammer Drill and Rotary Hammer drill

South African here - great video as usual ! From a practical perspective, so-called 'vibracrete' walls are very popular around the country, to put around your residential property - these things are well nigh impossible to drill into, even with the hammer drill - you'll definitely going to need that bad baby (even if it isn't cordless or brushless) - we need to put spikes on top of it for anti-home invasion security - I concur though - first make sure you get the best drill bits ! I'd say if you're going to shell out money, whichever brand, get a good cordless & brushless impact driver (good enough for normal drilling jobs as well, and these days useful for lug nuts and other socket functions too, in addition to turning screws), and use the big one for bigger drilling tasks - then you're covered all your bases. Note : Milwaukee, Ryobi, AEG & Ridgid are all owned by the same HK company. DeWalt is simply a rebranded version of what used to be Black & Decker, and in fact is owned by B & D. IMHO get a Makita if you can afford it - if not, get a Ryobi (I have both, neither have let me down). Back in the day I owned Black & Decker & Bosch, both had failed on me, so for me that rules out DeWalt and Bosch.

I'm new to all these electrical tools. Can I use or attach SDS drill bit straight away to a cylindrical chuck where I normally used a cylindrical drill bit?

4:51 I got the same hammer hehe

hey I have that twin batt but im gutted its not the American variant. now there is bigger again.

i wonder how a rotary hammer drill compares to a corded drill.

Looks like the hammer drill works fine on concrete

wasn't the BOSCH in reverse

the 8th drill hole was drilled counterrclock wise (in reverce monion) backwords is it even fair comparisn on the hammer drill ?

Helpful, but no one on youtube identifies the tools for particular jobs. I bet nearly everyone that visits these sites wants a tools for a particular job, e.g. putting up shelves, general regular maintenance around an apartment, renovating bathrooms or kitchens, adding a deck or garage. Drilling holes and screws at a given speed per watt or torque on hands is good to know, but PLEASE for future, talk about usefulness for a given need and expectation of a customer.

The main difference between rotary hammers are imapct it delivers, rpm and bpm But how to choose ? (What is ok and what isnt enough?)

It's a good thing that you've shown people that a hammer drill is pretty much a joke, something they won't tell them in the store (best just to rent a rotary hammer if you don't need it much). The only good way to drill masonry is with a rotary hammer.

So what about the main question????!?!?!!!! Does the different drills cause a difference in the hole diameter being bored out to where the anchor won’t grab as proper making for a weaker anchor

may i suggest not wearing flip-flops while working with power tools & concrete blocks..... ;-)

9:19 absolute madman lol

Flip-flops.

Its really not a fair test 2 battery drill against 1 battery cross bit against a single head bit. But i would still buy the hammer drill not the sds i need it for home use not professional use
