Don't Waste Your Money! 3M Cubitron vs Benchmark Abrasives 3-inch Roloc Discs on Amazon
Vložit
- čas přidán 14. 08. 2023
- Typically, when it comes to cutting, sanding, or grinding, 3M sets the standard in performance. However, with that performance usually comes a high price as well. Such is the case with these 3M Cubitron II Roloc sanding discs. We're comparing the 3M discs to the Benchmark Abrasives Roloc Sanding Discs that you can purchase on Amazon. Actually, we purchased both brands on Amazon, but the Benchmark was much cheaper than the 3M Cubitron II sanding discs. #3m #review #amazon

For the record neither of these desks are designed to remove oxide or rust! They are designed to remove material from the stock. Using these on oxidized surfaces just causes them to clog and fail very quickly, they make special disks for oxides and rust, they look like a hard sponge. If you would actually use these for their intended purpose they would outlast the discount disks at the rate of eight times plus. I use cubatron all the time and I’ve been able to grind down 6-8 inches of a solid one by one steel bar with a single Cubatron 2 inch desk. No one else comes close to that amount of metal removal!
i didn't know there were any "desks" designed for that use....
@@abruptlyblunt sorry for my mistake mr perfect!
Thank you for that knowledge. I didn’t realize this. So using scotch bright type material with mineral spirits or similar would be better
@@David-sp7gc no It's called a polycarbide abrasive wheel/disk or stripping wheel/disk
🤦🏻♂️
I bought 2" 24G for roughing out welds in tight spaces, 2"40G and 2"60G for finishing. I bought 3" 40G also for preparing for body work, 5" 60G for grinding multiple layers of paint and filler, all from Benchmark and all are blue Zerconia. They also have the best backer and nut assembly for the 4 1/2 and 5 inch electric grinder.I am very satisfied with all their products and their response to questions I had.
Thanks for the tips. Especially for the wrench mod :)
Never knew safety collets were supposed to be a feature. Thought it just got stuck. I loosen the nut and smack the nut with a wrench to release the bit.
Cubitron II is probably the best on the market right now for it purpose (and price) they grind 2x faster , last 10x longer than almost anything else (for me they last up to 20+x longer / or 15x compared to "green" premium brand in case of orbital sander discs)
belt sander in my case last 8-15x longer than other brands (or 3-5x longer than other brands ceramic belts
and grind .... uh... at least 2++ if not 3+ times faster and easier than other brand belts , my 550w bench grinder modified to belt sander grind faster with cubitron belts than friend 1kw belt grinder with "standard" belts"
but in case of rust removing ...check Norton Blaze Rapid Strip (and any other norton blaze abrasives) they have waaaay stronger and way more flexible glue that let you push as hard as you can without damaging the grain etc , it have like 70-80% performance of Cubitron II and last 70-80% of the Cubitron II ...but damn where Cubitron II will get shred into pieces , Norton Blaze hold like if its nothing (its avesome for sharp corners , rollock , grinding nails etc)
I would have been more interested in grinding metal not removing rust. I have been using these exact cubitron disks for light stock removal for around a year now and I haven't used up one yet.(small parts and deburring ).
I’m honestly not surprised. I recently bought a 10-pack of flap discs from Benchmark Abrasives for my angle grinder and I’m very impressed with how well they perform. They make excellent products.
Nice review....I work in a tool and die shop and do a lot of die grinder work...Switching between 1 inch 2in and 3 in pads...I just leave in the arbor and unscrew the backing pad...I use the 3 in on 2in trick also...
Excellent review, you sold me on not only the benchmark but the Milwaukee die grinder. The 2” bonus info is a great fact to point out. I haven’t used any 2” but hey, why throw it out if it’s still useable? Thanks for the great review. I also just subscribed to your channel.
Great review 👏👏👏👏
Well done, thank you for a factual, results based review.
Wow, great vid lots of good tips, keep it up showing ur tips u learned with exp. Noice!!!
It's not designed for 3" discs. 2" should be max if you want it to perform as intended. Notice how much more power it had under load with the 2" pad. Not saying you do this but I see many people bashing this grinder for lacking power meanwhile they're using out of spec attachments which is unfair to Milwaukee and to consumers reading those reviews trying to make an informed decision. I hesitated and held off buying this grinder for months because of the many reviews bashing it, up until I saw a special sale on it that I couldn't pass up and then when I got it I couldn't believe how much power it had. I use 1" and 2" attachments and it has all the power I could ever need.
Love the 3/4" Benchmark flap disks..I've been using them for almost 2 years now.. you're right Tim..Benchmark is killing it
17:45.. nope...that Millwaukee grinder doesn't have the guts to heel on it and get everything outta those disks...
Additionally, if you match your backer to the disk size they'll actually last longer because you're getting the surface area to distribute the work on your disks... they'll last longer...👍
Thank you, ordered via your link.
been using benchmark for a couple years now. Good products!
Another great real world comparison! But the 3" to 2" hack is genius!
Have you done a review on Benchmarks grinding mask yet? Curious on that one.
What brand and model of scissors are those
I'll have to try some of those discs out I go through quite a few of them. I started using is the Hercules flap Wheels that fits the 3M 3" roloc pad . They come in a pack of 3 . You should do a review on those they're quite nice actually. They also seem to save the roloc adaptor they keep the rubber from overheating and coming apart from the anvil .
Great video
Try grinding mill scale and welds, otherwise this test is inconclusive.
I haven't used these discs, but I use Benchmark 5 inch cutoff discs for my grinder and they're very good. They're .80 a piece and do better than any others I've tried that cost twice to 3 times as much.
Great video! Really makes me want to pick up a Ryobi Die Grinder.
I enjoy my MkE die grinder. People’s issue is they press hard in it instead of letting the tool do it’s job.
IMO... Having a jig that would apply the same pressure across the face of both discs and adapting the jig so both were used with Identical down pressure would have been a far better test.
Yes and no, I used different Rolocs and from the cheap to the 3m its a huge difference right away and you can notice it instantly. If he’s honest of course I think its a really good test showing the cheaper disc works just as good
Jesus man. Just get to the review.
For anybody interested, he starts actually using the discs around the 7:00 minute mark.
One problem I saw with this test is that tool has too much RPM. I run a slower rpm on both air and electric, it gives the stones more time to get down in and cut while building up less heat making the disc last longer.
I've watched so called 'professionals' waste disks at incredible rates simply because they are *IGNORANT* of what modern materials are capable of, and *STUPID* for refusing to take heed of a simple lesson that shows them the correct, as in superior, way to use their tools.
Last year I had a steel building erected, its frame was made of 3" galvanized square tubing. The 'foreman' had to make cuts in the pieces to accommodate doors & windows. He 'used' almost one full disk for each cut, and three full disks to open up a 12" notch for passing pipes. And I'm not counting the disks he simply snapped off because he twisted the tool. his crew went through disks almost as fast doing the long cuts on the diagonals of the gables, and trimming the openings. It was *painful* to watch.
I've had *ONE* 0.045" SAIT disk in my Ridgid angle grinder for over four years and I've used it to contour the bucket on my backhoe, trim aluminum door frames, fabricate a landscape rake for my Gator, a terrain rake for my skid steer, clean up welds, carve concrete spillage, bevel & trim Unistrut, and so much more! The only thing that cost me nearly an 1/4" off the diameter of the disk was when I tried to grind in a piece of hard porcelain, not the so called "porcelain bathroom tile", this was the real thing.
OK, OK, I don't use it every day, but I've got eight batteries and four chargers, so when I do use the grinder, I work it until all 8 batteries are drained, and all 4 chargers are filled.
I think if I were to buy a $40 box of 15 Cubitron, I'd need to include a dozen of them in my Last Will & Testament! ;^)
I can’t get past the poor performance of that grinder sucking up half the battery in 2 and a half minutes…But nice review, Thumbs up,
I don't know about hand applications, they can be very particular. I have used Cubitron in the past on automated grinders where life was tracked very closely. Belts were inspected for wear and samples kept for certification purposes. Cubitron saved us nearly $100k a year over competitors best efforts. But again, that wasn't a hand application, those robots were very aggressive and I don't think you could hit those mrr's by hand.
I've been buying from benchmark for a long time. I like their products and the pricing is fair. Performance is top notch. I wish they would go into supplying band saw blades as well.
Mk Morse makes great portaband blades. I'm sure their larger sizes would be nice too.
Cubitron convert here. They may be a couple times more costly but the time saved and its durability far outweighs any pennies saved.
I've been using Benchmark for years.
Norton Blaze (ceramic) is the best abrasive I have ever used. I wonder how the Benchmark ceramic compares?
I feel they have the best backing material also. Very easy to cut and shape if needed
Sir, you are using the wrong product for rust removal. I recommend try the 3M Clean & Strip XT Pro Extra Cut (Green) for heavy rust with mill scale. 2 " and 3" quick change (rolocs) are available. You will see a dramatic difference that the Benchmark abrasives can't touch.
Those cubitron disc's clean up easily with a rubber eraser.
if only there was a disc meant for rust removal😂😂
I honestly think the nylon wheels are the best thing for removing paint
my thought, they are like dollar tree alkaline batteries, yeah name brand alkaline batteries are twice as good, but they are more than 4 times the cost which means you get twice the battery power from dollar tree batteries for the same price as half the power from name brand.......
I am so glad I passed on big red die grind bench mark for the win
I don’t even have to watch this to know 3M cannot be duplicated in my experience they always last longer perform better
I agree, but not 3X quicker or 3X longer.
@@Bob_Adkins this is not a good test, i guarantee you the 3m wheel will cut down 3x as many welds 3x faster. this test would have been way better off just using a wire wheel
@@ShellYeah03 Apples and oranges. Welds are ground with angle grinders and hard 4"-8" grinding wheels, or at least flap wheel. No doubt any of those will grind 10X faster than little 3" hook and loop on a hobby die grinder. No doubt the 3M is by far the best, but not way better than the Benchmark 3" hook and loop.
@@Bob_Adkinsyeah 8 to 10 times longer!!!!
Does the tool keep shutting down…what’s going on?
Milwaukee says the grinder is meant to use only 2 inch discs
Looked like he was putting more back into it for the benchmark. But, overload protection.
Their regular grinding disks for mini grinders are unreal. Theres no real comparison
"list price" is 52 bucks (40 bucks is the discount price) for 15 disc's????? That's just cooky talk...
All these reviews are great for the companys and users but soon after the company get the exposure they increase the price
Use them for what they are made for and see how they compare...
3m is the only roloc I’ll buy last so much longer than knockoffs.
Oh yeah, clearly.
So what you're telling me is that I need to have 2 die grinders so I don't hafta switch out between 3 and 2 inch holders? Got it, thanks for letting me know that it's best to have 2 tools instead of just one 😄😄
You should have tested the cheapest as well
The video was already running long, so we didn't want to include the cheapest. They performed about as well as could be expected...terribly. Thanks for watching.
I hated that Milwaukee safely release feature so much. It wasted so much time, when you have to switch out. Wish Milwaukee would stop babying the users so much.
Right. Oh no a half ounce disk might go flying thru the air, possibly causing a light abrasion.
@@Chris-du7hi I had a 3" cutoff disk break, no harm done. Out of curiosity, I looked for the broken piece but couldn't find it. A few months later I found it struck in the ceiling, all the way through 3/8 plywood. I use a face shield now but still hate guards.
I don’t know why they wouldn’t use the Ryobi grinder. It’s a much better grinder. This Milwaukee cutting out so much is really annoying. Also the battery dying in 5 minutes (theoretically) is a joke.
Might as well use a plug in drill instead. However, I’m glad to have been introduced to Benchmark Abbrasives. 👍🏾
Because M12 is much more.compact. they are already bulky enough to people coming from air grinders. Size matters to some people 😅
I agree, the Ryobi is a much better grinder. I got the Ryobi and 3 batteries for $200 on Ryobi days. Every test I’ve seen on the Milwaukee shows it shutting down constantly under heavier loads, especially with cutting discs.
Shit, my M12 die grinder cuts off under ANY load. Thing is a joke. And I'm only using it for surface cleaning, not even trying to remove any base metal.
I guess a couple things here in case you hadn't noticed. This Milwaukie die grinder was never meant to be in a production shop doing heavy grinding all day long. So that's the first thing. Secondly, it's not rated to spin a 3-inch disc! Especially in this heavy-handed time trial application like he's doing. And the last point dovetails off the previous one he is quite heavy-handed and I understand that we're trying to see how fast it can be done but that is the reason why. The tool was not designed for that. But then again how much is it to buy a high horsepower die grinder and then the compressor to actually keep it running? That's not cheap either, so I say it probably doesn't do too bad.
@@brizzle8797 I own a bunch of Milwaukee tools (M18) and like them a lot. In this case though I think the Ryobi is the superior product at a lower price. I like the option of being able to use 3” discs if needed plus I like the one wrench tool change. The Milwaukee just seems to shut down too often for my liking.
Run the 3in on the 2in don’t cut it off. Wasteful. It will wear down.
no way that can be true
Ok. Do you have any info why?
I was kind of confused at first because I saw "Cubitron" vs. "Roloc". These are both 3M brands/trademarks so the Amazon ones aren't actually *Roloc* discs, they are knockoffs or "aftermarkets" that happen to fit on the Roloc system adapter/thread. Anyway that said the result is pretty good. However there do seem to be a lot more "complaint reviews" about the Benchmark ones on Amazon, than there are for the 3M ones.
There's also a better tip for the stupid dual-wrench collet on the M12... Use the Ryobi HP angle die grinder 😅 Not only is it way better than the M12, it also has a lock button so you only need to use one wrench. How TTI didn't do this on the Milwaukee is a mystery. But I do get the explanation of intentionally using a weaksauce grinder.
Do Milwaukee batteries fit it? If not, it's not worth it.
Looks like 3m is hoping people will think these as good as the sandpaper
Country of manufacture is an issue to me too.
Go ahead and support Chinese ripoffs. I'll stick with what I know works.
For the price of these m12 tools the performance is junk, they are cool but if you already have the air tool there is no reason to “upgrade” maybe if they find a way to jam 21700s in them they wound not be so bad
The M12 die grinder is not as powerful as a good pneumatic die grinder. That being said, the one I have is one of my most used tools. My 60-gallon air compressor is not all that portable.
@@gman9904 I don’t own the m12 die grinders but had my eye on them for a while. I own two matco air die grinders and two cheap Amazon ones. My issues is I have a 15 gallon 200 psi dewalt compressor and I hate that it runs every 5 mins. I try to mix up air and cordless. Coworker came in with both of the m12 die grinders and the newer 5.0 batteries. With full charge they would bog down it you put 2-3 pounds of pressure into them. It sucks because there’s plenty of 18/20v options but only large straight grinders. I think ryobi has a die grinder that’s basically a 18v drill which is crap. If Milwaukee could up the torque by at least 50% maybe they could justify the roughly $440 for two bare tools.
Once or twice a year Home Depot will have a good one-day sale. I bought the right-angle grinder with a free 2-amp battery for $149. I also work with wood and plastic and this grinder works good for that. @@KZ-yy9pm
@@gman9904 Get a HF dolly and a 100' extension cord and then your 300# compressor is portable! 😛
My M12 won't run anywhere near that long without shutting off
Neither product can perform well when the operator abuses them! Ever hear: "Fast is slow. Slow is fast."? By trying to be 'fast' with the operation, your results are slow and inefficient. If you had slowed down, not only would the edges of the disks not worn out in under a minute, the material would have come clean, as in free of mill scale in less time and with less battery.
Get what you pay for.
Benchmark bought video... 😂
Hey, sometimes China comes through lol
Quit repeating the facts!! We're not STUPID! I don't have time for this!!!
OMG-SERIOUSLY-you want me to watch all that-you don't deserve any views-WHAT SLOP
Omg, who taught this guy how sand stroke the entire 2' or 3' piece up and down then play out rest mess rust coating from water or rain 🌧 Go back school and get some lessons I did better back in 1977 for God's Sakes at Saw shop
🤣🤣🤣
We followed the Mr. Miyagi method of Sand-on, sand-off, was this not correct?!
@donald4416. What? I don’t understand what your saying.
On the subject of school, you must have missed a few days. One of which was when they were teaching “How to end a sentence”.
Don old mate I reckon youve got the experience and I could learn a bunch of valuable things. I just have no idea what you're saying
Dang it
