545 Diamond Cutting Wheel (22mm) 10pcs with 402 Mandrel (3mm) 2pcs and Screwdriver for Rotary Tool by MoArmor

These Dremel alternatives are the dope. Worked great. Got 10 instead of the 1 you get from Dremel at half the price. The Dremel cutting wheel doesn't last much longer than the knockoffs. I used it to cut ceramic tile for my bathroom and it worked great!

I bought these just to cut a 1/4" pure tungsten rod, so my comments are limited to that purpose only. The product is called a "diamond cutting wheel", but if you're thinking of using it like a little circular saw to cut a slot in the tungsten rod, forget it. This is because the diamond bits are only on the faces of the wheel and the edge of the wheel , not embedded deep in the wheel base material. If you use the edge like it's a little circular saw, the diamond bits are knocked off of it pretty quickly. However, the diamond-coated face grinds the tungsten wonderfully well. And so far, the one side of the one disc I've been using seems as good as when I started. So, what I'm now doing to cut the tungsten rod and get flat, clean ends is I put the rod in a vice, use a hammer to break off a slightly longer piece than I want, then clamp the piece in the vice and use the disk to grind the ragged end until it is flat and clean. Ugly, I know, but it works. I would definitely buy this product again, but I doubt I'll need to, because I haven't even worn out one of 20 sides of the 10 wheels I received.

3 stars for value. You get 10 cutting wheels. I used them for cutting stone and the worked great. The wheels don't last too long but what can you expect when cutting rock. I was ready to give it 5 stars when i began cutting. The wheels are very effective at cutting stone. However, both arbors stripped before before i could use more than 3 wheels. I ended up using a dremel brand arbor and continued to use the wheels. From there on out all was good. For the price you can't beat em but be careful tightening the wheels to the arbor or just use another arbor.

I really like that it comes with two mandrels so I can swap out a hot wheel for a cool one real quick. Only started with the two so far and I'm really not sure when I need to use a new wheel, then again I would say I don't use my rotary tool too often. If you're NOT cutting hard metals this is for you and it'll probably last forever. Get rid of those cheap resin cut off wheels that fracture from being looked it. I strongly recommend for hard materials that you do get a quality reinforced resin cut off disc though.

I had to cut a long rectangular hole in 7/16" porcelain tile without actually piercing thru the back side of the tile. The long cuts were made easily with a DeWalt circular wet saw (https://smile.amazon.com/gp/product/B003BVW5NU), but the short ends and the corners were problems. The logical choice was a diamond blade in an oscillating multitool (OMT), but I was unable to find one that would cut this stuff. These blades in a Dremel tool worked great -- fast, smooth cuts. I had to be careful because they were cutting almost too easily, and the small diameter was awkward - a very long arbor might have helped. I wish they'd make blades for the OMT.

I bought these to cut out some bigger drain holes in my bathroom floor tile in 5 apartments, after running through 3 rotozip tile bits and only getting through one hole i turned to this, not expecting much as they look pretty thin and cheap, i was expecting to run through the entire pack but nope, i actually used one to cut the 4 holes and its still good to keep on cutting, its a fantastic tool and im very pleased with it, will definately buy again...

Works great for cutting glass. I cut a beer bottle in half and the blade doesn't even look worn. These are smaller than the Dremmel brand diamond cutting discs, but they cut just as well.

I WAS using the Dremel reddish brown abrasive cutting wheels to cut a corner off of a stainless steel backsplash tile to allow access for the wall plate screws.I went through five cutting wheels, one by one, watching their diameter's quickly decrease as they spun. BUMMER... I ordered these diamond cutting wheels and problem solved as they spun up and sliced that little edge right off. These inexpensive little wheels are the right tool for this job.
