I know this is an older video, but there are some things you should know. First, you’re applying too much pressure when you’re cutting. This makes it more likely that the regular wheels will break. Ease up and let the abrasives do the work. If your grinder slows down much, you’re doing it wrong, period. Lots of guys do this. It’s still just as stupid, no matter how common. It’ll also wear down your diamond abrasives faster. Second, it’s an abrasive. They all heat up the metal a ton. Third, the regular wheels aren’t worn out until they’re stupidly small nubs. The abrasive is impregnated throughout the cutting portion of the disk. If you can still reach the metal while maintaining the right cutting angle, keep cutting. If you have to change the angle, use a new disk. Smaller disks can be used to cut small pieces of metal where maintaining the angle is easier to avoid waste. The cutting wheels that are made out of steel have one advantage. They are safer to use because they can’t shatter like a fiber disk can. If you have to cut in a bad position, like under a car, or cutting pipes in a crawl space, it can be difficult to hold the tool perfectly straight. This is where they shine. If it saves you one trip to get stitches, it pays for itself many times over.

Excellent job. Good luck with your projects. Hope your channel grows quickly.

Diablo, all around, makes an amazing blade. No shilling here, I've honestly done a lot of pro-sumer grade work with them and they still amaze me. Like all fast moving blades, though, heat is your enemy so take it slow and don't force ANY grinder mounted blade if you want a long lasting implement.

You will find that it cuts much better and safer if you drag the cutting wheel and don't try to deep cross cut like you are doing. If you keep pushing it through the work someday it is going to kick back and cut your gut open like it did mine. I went to the hospital with my guts hanging out. It took about eight months recovery before I could go back to work. I was very lucky it had not been my face. First make a groove across the material and then start following the groove a little bit at a time.

Nice Video... I've used one also and have relegated it to mostly the other materials listed on the package. I agree with the others about the grinder operation. Sparks are not that big a deal and you don't have to stand directly in front of them. A welding jacket like you wear should work great.

First time to your channel. Just starting my journey in metal. Great comparison. Subscribed!

A few ideas worth sharing, if youre still getting your feet under you with cutoff disks, 1. get a 4 1/2 inch grinder that is only like 4 or 5 amps (harbor freight), disks just dont explode on those very often. 2. dont cut things that arent secured in a vice or clamp, if your work moves fast while cutting, youre going to blow the disk. 3. be extra careful when you finish the cut, if the work is under tension, or heavy, it can pinch the blade. This goes for any cut, but its worth noting. 4. I have a lunch box I keep my cutoff disks in, separate from my grinding disks or diamond blades, treat them like a cd, if they get smushed in the bottom of a tool box, or steped on, or a grinder rigged up with a disk gets dropped, even lightly, THAT is when you retire the disk without question. Keep them padded and stowed safely until you cut, then take it off the grinder for storage. any old disks that have been kicking around, ditch em. That will eliminate 75% of disks exploding. Good luck continuing to learn to weld bud!

You get more life with these but you gotta take your time and not force it otherwise it will cut like shit . That's my experience with these .

The point of the diamond wheel blade is that it will last longer than the old composite type cutting wheels. I used two of that same blade and I was not impressed with them. I am back to the old composites. My chop saw is a metal blade and cuts great! I'm new to plasma and that thing rocks! Thanks for the video!

How about grinding in the correction? Sparks flying to the front. Dragging it towards the body on a slip

The grinder, I've been working metal my whole life some of my most serious injuries have been with a grinder I can understand why people are afraid of it specialty cutting but once you master it will become your favorite tool you probably won't even go to sleep unless you have one under your pillow

I have one of those. I'm not really a fan of it, myself.. After watching your video, maybe I'll give it another shot..🍻🍻

Do you think you turn up the volume when you are cutting/grinding? Because that sound never gets old...

Howdy from Bangs Texas

How much faster did the diamond wheel cut vs the standard?

Nice video

the problem with fiber cutoff discs is the smell and dust, a metal cut off disc eliminates almost all of that

Is the diablo cut off disc not prone to breaking like the abrasive cut off discs?

I prefer the inexpensive standard Cut-Off Wheels in most cases. The Diamond Cut-Off Wheels require a much slower cut to get good results. But time is money, and in my opinion my time is more valuable then the cost savings of longer lasting Diamond Cut-Off Wheels, and the standard Cut-Off Wheels make a much nicer and cleaner cut. Cleaning up a cut from a Diamond Cut-Off Wheel is more time, effort and money. Best wishes...

Two one foot cuts of 1/4" AR plate it was bare metal rubbing to cut with sheer heat lol gimme the abrasive bonded hands down I do swear by Diablo though!

I put up with a diamond cutoff because it's safer. I have had the abrasive disks explode a few times.

Great video ! ! I'm wondering if you think this wheel would do well cutting copper pipe (non ferrous) as that's all I'll be cutting. If not this wheel which one would you recommend?

Try the Diablo metal sawzall blades, I use those instead on my grinder, much safer, faster, and much cleaner!

You should check out millner tools, they make diamond coated cutoff wheels basically guarenteed for life. Expensive though at around 150$ a per blade

Good video but as was said below, go slower and it cuts cleaner. Disadvantage: much slower (and perhaps rougher cut... I seem to get cleaner cuts than you got in the video). The advantages are: longer life (by far) and you need not worry about the wheel disintegrating and becoming a "grenade". I have crashed my metal / diamond cutoff wheels many times, to the point that they bent in use... yet they remain intact! AND, you can continue to use them... the little bends seem to straighten themselves out with use. So, IMO, these are best when you have to cut something in an awkward position where you might otherwise "crash" a fiber wheel and blow yourself up...

One pass along the edge and that cut is cleaned up. So the comparison is only for cleanliness of cuts? Seems like one cut is a small sample size to make a comparison. The big selling point is durability, ergo value. When i bought my angle grinder i got a few discs, flap wheel and this item. I was a little scared about wheels breaking after seeing some safe usage vids. Its been incredible! Can't say if it would last 100X longer because i have only burned through a few discs and this is going strong. I can say that at $10 and most wheels at Lowes (where i got everything) were $3 or more, its well worth it. For those with more experience than me, definitely worth a shot.

If you cut a lot of rod, bar, strip, angle etc. get a real chop saw with a dedicated carbide steel cutting blade. I switched to one and cutting stuff up is quick, clean and accurate and it doesn’t make the mess an abrasive cutter does. It also leaves the steel pieces cool to the touch.

Does it matter which way you install the diablo blade ? I have a M18 i just bought. Thank you sir

Respectfully, you're holding the angle grinder opposite of the path of travel. Recommend to NOT use it so it can kick back at you; rather, turn it 180 and allow the draw blade to spin clockwise and 'pull' into the metal. How you're holding it can certainly cause you a safety issue. #2. (@5:49) Your other blade is a 'cutting' blade, not a 'grinding' blade. You're confusing people my good sir. Check this out at the 30 second mark: kzfaq.info/get/bejne/qJZ_nNaqtZbQhZc.html. Cheers and wish you safety in all your tasks.

I use one to cut cast iron tubs

In a Nutshell: diamond blade = Very high burr formation, more noise, and longer cut. However, better tool life and no dirty abrasive smell. No way this product is beneficial in mass production/fabrication. maybe it's a fit for the guy who does 1 cut per year in his garage.

you should try it on harder metal such as thungsten/titanium :D

If you want cut get a skill saw that's a grinder is meant for grinding no matter what kind of blade you buy

Hold grinder so the sparks shoot downwards toward you. That's the proper way to cut. Its safer.

Hi! Don't worry about the noise man. MAKE MORE NOISE THEN THEM 😆

On the packaging Diablo claims the diamond cut off wheel last 100x longer than standard abrasive wheel. If this is true it could be very cost-effective.

Well, this wheel is an interesting concept, but it looks like its not as good as a regular cut off wheel. This is the first I have heard of that wheel. Ill do some more research on it, but I would stick with regular wheels. Great video!

Only work for tiny cuts. Anything thick quickly heats the blade and causes it to warp and cut like crap. They last forever but don't cut near as well or fast.

Never turn your grinder around like that because now it will kick back the sparks always should be directed towards you.

My grinders are my children It's the most versatile tool I have And doesn't scare me But a jigysaw now

To avoid a kick back, you need to hold it straight. The Diamond Cut Off Wheel will last longer but it cuts slower... For faster and cleaner cut, you may need grinding cutting disc as this as possible, but the draw back will be it gets shaven off quicker too... IMHO... 😎

As it relates to tolerance..the dimensions of the value of the object...not keep it's shape

If you try just marking the line and begin the cut on the end of the metal closest too you. and proceed in one direction ( away from you ). And dont make several cuts on top of the metal, just start at on end and cut all the way though to the other end. It will turn out better. Just sub you, great vid.

For your safety and working knowledge of tools watch videos of welders show you proper technique learn the correct way use angle grinder with practice grind / cut like a Pro 👍using that Diablo blade

For the price of all blades I use even the broken and have had a feel minor injuries but it’s expected doing that type of work

SUP!

Bosch carbide wheel better solid metal wont break cuts metal wood plastic ceramic stone brick

you are cutting backwards my friend, the blade must be facing your left if you are right handed and sparks fly towards grinder handle.in the way you are cutting, you can't see the edge of the blade or the markings that you have made on the piece of metal. also if you let the angle grinder a little too loose in your hand it will fly straight in your leg, it will run the blade straight into you. please turn the angle grinder handle (the black one) the other way. after a few cuts, trust me, it won't be so scary anymore. best regards.

breifly looking at the comments im surprised no one is telling you your using the death side of the grinder (hence the death grip!!) , thats why its so sketchy, and i know why, to shoot the sparks away from you, yes it sucks to throw sparks at yourself but if you use that other side you can use it one handed easily, so much less dangerous, please consider this!

hi!

Hi. Just subscribed to you channel. Looking forward to future and past videos. Your comparison of the diablo cut off wheel and the fiber cut off disc is not that accurate. I notice you technique was different for the two. And I'm more afraid of my table saw than my angle grinders.

hi! 👋

Cut in the wrong direction sparks should come back at you!

Its alot slower than the abrasive one . I make knifes every day cutting them all with this method. I dont have a forge so I just use grinders . I won't buy another diablo. Burns my batterys out so fast with little to show for.the sanding disk and abrasive disc is all I use I barely even use a grinding disc . That sand paper disk will take metal of and shape so fast... when I first saw the diablo I thought hell ya this is it. But I quickly was disappointed. Now that's for mild steal and hard steal . Maybe good for some other material. Well you know what . Its probably because my batteries suck. If I had a corded grinder with faster speed and stronger. I bet that's what it is.. I have 4 batteries I go through them so dam fast . I need corded tools.i got the full DeWalt tool set as a gift , so I've been using the hellmouth of them. I enjoy making knifes. I just harden with the oven and or torch..make handles with deer horns mainly, I'm in Texas and realy like the Mosquite wood to it's real hard and red . That's all I use to BBQ with to so I keep it around..have a good one...

FFW TO 4:10

Hi

well for 1 it lasts 100 times longer, for 2 no silicon carbide dust and fiberglass dust to breath into your lungs 3 who cares about the cleanup if you have asthma.

Wow! You should probably just stick to wood bro

Whatever blade you’re using the way to get the most life out of it, hands down, is take your time and “score cut” meaning take numerous passes on your material. Especially with abrasive disk.

Four minutes to get to the beef? Come on, man!

I'm married I'm use to living either noise 🤪

Yeah you doing wrong You should position the grinder on a way the if gets jammed it will pull the grinder away from you Not on a position the will kick back onto your face.i hope this makes sense for anyone

Mate, you need to educate yourself on the matter before posting undocumented stuff... It's not the brand which matters.. There are a few reputable manufacturers of such wheels and all perform similarly. It's not about a bit of burr, which can be handled by someone who operates an angle grinder, it's about the benefits of using such. First off, it will hold the cutting diameter. Imagine you have to do a long cut; what are your options, to exchange a ton of wheels, or simply use one which does not "melt" under your eyes? Second MAJOR benefit is safety; these wheels don't splitter. Third benefit is monetary; just do the math; 1000 cuts on a $15 wheel compared to three0five cuts on a $1.5 wheel... Next is the wheel dust of the traditional over zero dust from the metal/diamond one. Next benefit: No smell!!! That's a big one if you work in a living space (yes it so can happen that you need to cut something off at your or a customers home). Now, you keep going over traditional because you're to lazy to clean-up a cut... Merry Christmas!

The rules of thumbs I use are: Diamond is a tougher abrasive, but it usually cuts slower than an abrasive impregnated ablative disk. An abrasive disk does cut slightly cooler, because the abrasive/medium that is spent is thrown off taking away some of the heat. Still nothing controls heat and precision like a light touch and taking a bit more time. Diamond 'cut-off' wheels usually have a thin kerf, with diamond abrasive only along the outer edge. It wears out quickly, and leaves a rougher edge as you cut by hand, because only that very edge is grinding when you make contact of the side profile. With a regular grinding disk, which is fully impregnated the whole disk abrades the working material over it's entire surface... which leads to a much smoother edge/cut. (A stationary, or mounted tool, obviously cuts much better in either case, but I've never used one in the field. I grab a framing triangle, and use it to run a straighter cut using the grinder's blade guard... but for me, this is only a little better.) Mostly I use Diamond grinder blades when shaping and cutting tile. Honestly, that is where they really shine. Hand cutting I use the abrasive blades on metal... and I go get a shield if I'm doing more than a couple of cuts. On mild thin stock, such as you are using, I did one time pull out my own carbide diablo blade ($60 80-100T?), instead of the stack of ($10) cut-off discs. I'm afraid of those things, and I've never liked cutting with with a shrinking diameter blade; or worse, having to change the blade in the middle of the cut because you are trying to get the most out of the blades, and the saw bottoms out. Did I mention that a 12-14" blade can go half way through your head before you even know you're dead? The carbide worked well for me this one day, making lots of very reproducible cuts in smallish stock, but that's but that's not enough to give a strong recommendation. Clamp your workpiece; steady light pressure; steady advance. Good luck, and be careful. Cutting metal with a high speed tool is always inherently dangerous.

you want to hold grinder firmly but your pressing down way to hard and starting a cut at the rear and pressing forward is a big no-no start a plunge at the top or north and pull back maintaining the plunge depth all the way back maintaining good speed letting the tool work ..Your gonna get hurt and your gonna burn up a grinder bowing down on it like that. It's not a lumberjack competition.Keep all your parts where God intended...

hi

The construction sucks, worst i get is tree crews cutting and chipping

Let the tool do the work stop applying so much pressure

I’m high In the comments lol

Search for *Grinder Safety: How to Properly Use an Angle Grinder* for a more comprehensive guide. That video is about 45 minutes long but it is the most comprehensive and easy follow guide on how to use a grinder safely and most of the attachments available (and how to use them). About 1.8M views so far. Think of it as an insurance policy to your health so that you don't get hurt. No disrespect to the person who took the time to film and edit this video but the way he was holding, using and cutting with the grinder is BACKWARDS and DANGEROUS to those who would watch this video prior to using a grinder of their own. If you are right-handed, the screw on handle is mounted on the left (instead of on the right like they in this video). Also, the bottom of the cutting wheel should be facing left instead of right in this video. Why? the rotation of the grinder/wheel (most I am aware of) is clock-wise when looking at the top of the grinder. When cutting, the grinder/wheel should feel like it wants to move away from you instead of toward you. The sparks should be flying toward the floor and not away like this video. If you hold it wrong like this guy and you lose grip, the grinder/wheel will move toward you or your leg and you would be going to a hospital.

This was a bad comparison video sorry man i dont mean any hate but you barely compared anything. All you compared was the cut.

I hate these disks!

We cant even hear anythi g...youtubers are so sensitive with sound that they can only hear

Bad comparison! Sorry dude.

buddy has no idea wants he's doing
