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

Good, solid cutting wheels and spindles. Comes with two spindles and a screw driver to attach the wheels. Great for the price. Some seem to wear out faster than others, but overall they really cut well. For the low price, much better than single Dremel replacements you can find at the big box stores.

I was installing a backsplash and needed to cut the glass tile rods to size. I read reviews about this working great to score and break tile, so I decided to give it a try. Just as others have said, you can score and break glass tile with almost no effort. I quickly learned to rest my hand on the bench top to prevent the Dremel from dancing around. I wore goggles and a mask because it does create a cloud of glass particles that I did not want to breathe or get into my eyes.

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.

I ordered these diamond cutting disc for a tile shower project. I only had a few cuts to make so didn't want to invest a lot in special tools. After completing my project the first disc shows hardly any wear! I used water for all my cuts and it cut the tile with no problem. I probably have a lifetime supply! I will start looking for other uses for these diamond discs.

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 used these for cutting a variety of kitchen backsplash tile, glass, stone, glass over stone. Fantastic for cutting detail or interior cuts needed for electrical outlets etc. They have decent life and I think the price is very fair. Remember to apply water as you cut especially on glass or it will get red hot very quickly!

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...

Don't expect a quality tool for such a cheap price.
