20mm Diamond Drill Bit with Pilot Bit，Tile Glass Hole Saw, Suitable for Tile, Ceramic, Glass, Porcelain, Marble, DIY Kitchen Bathroom Shower

Some old drill bits had worn out and I really couldn't get through the hard porcelain tiles. This one worked much better. I only used it 4 times to cut holes for radiator pipes coming up through the floor, but it cut holes much easier than my old, blunt bits, and still looks in good shape.

Worked well, did the Job I wanted it to. Cut through wall tiles with no problems

Used to drill hole in bathroom tile during fitting of new toilet. Worked perfectly. No issues

Used it in floor tiles , the pilot drill didn't last long. Saying that, it could have been down to the way I used it..

This worked well again, this time purchased a larger dim' cutter (45mm), see pic. Cut no problemI would advise using water when using cutter prolongs the diamond material and longevity of use and clean any materials off it too.Cut clean through the Hardie Backer board.Ordered wrong size to get job completed, but ordered from vendor the right size to be delivered tomorrow, the other size was accepted to be returned.Can't fault the product, not a professional,just a DIY'r so suits my purposes l, don't know how the would shape up on a site etc.🌟🌟🌟🌟🌟

Really good cut only used a few times but had been a nice clean cut every time would definitely buy again

Rubbish item would not even mark the porcelain tile that it was supposed to drill

Good quality does the job perfectly!
