10 pcs Diamond Cutting Wheel Cut Off Discs Coated Rotary Tools W/Mandrel 30mm for Dremel

Used to cut steel shelving to size. Cut 4 shelves before it started getting dull. Cut bolts and screws with ease. Liked case.

I used these to cut square profiles out of 1/4” ceramic tile, because I don’t have access to a tile saw. Using these with my Dremel did the trick, but with some caveats.They don’t last long. I think each disc were good for about 8-10 linear inches before becoming dull. Good thing this order included plenty to use.Quality was inconsistent. I had 4 discs that had an uneven coating of diamond.If your a bargain hunter, this is good enough.

the discs wear out very quickly in the area you would need most, the edge, although i have not found a good miniature diamond cutting disc that holds up for any real amount of time, so all- in -all, not terrible, you can afford to burn through a couple discs and still come out ahead of what just one will cost you from a big box store

I was somewhat leary on buying these. Read some reviews and decided they were worth a try. I was really surprised. I was installing glass and stone back splash in my kitchen. I used these in my dremel tool to make the cutouts for the switches and outlets. They worked great. Had 10 cutouts and only went through 2 blades. you have to go slow in the glass , but it cut thru just fine. I am impressed and would buy again if I needed to.

They do the job but like all diamond tools you need to not over heat them.

It is serving its purpose.

Used these with a Dremel to cut porcelain tile during a shower install (piping / niche etc) - work great.

These blades along with the dremel flexible extension worked wonders for cutting tile (glass and ceramic) in tight places with contours and angles. One blade worked for the whole job just don't rush it and let the blade do the work. Great deal.
