1 Inch Diamond Hole Saw with Pilot Bit, 1" Tile Hole Saw with Center Drill Bit for Marble, Granite, Ceramics, Porcelain Tiles, 1-1/2" Depth of Cut for Thick Countertops

I installed a RO system on my own and had to drill into a 1.5inch countertop for an additional faucent. I followed the instructions and was able to make a nice and clean hole through without breaking the bit. No issues.

I needed ONE good clean 4.5" hole in porcelain tile and this did the job perfectly! Clamped tile over a plywood piece securely to the drill press table, set spindle speed to 900rpm, using pilot drill and as soon as the cutter touched the tile I removed the pilot drill, slowly feeding cutter while keeping area flooded with a water spray bottle. The cut was super clean and accurate. I could not be more happier, worth the cost for one very important hole for our walk n shower!

This hole saw did the trick. Cut thru porcelain with ease. Very happy with yhe performance

This diamond hole saw is exactly what I expected—nothing too cheap, but nothing to get excited about either. I bought it for a specific job, and it performed perfectly. That said, I have my doubts about how well it would hold up under heavy or repeated use. If you’re a DIYer who doesn’t need contractor-grade tools, this will absolutely get the job done.

Works great!

Worked as advertised. Run it slow with water cooling and it poked right through

Drilled through the granite table top with no problem.

I needed to cut a hole in a piece of porcelain tile for my shower head pipe. It cut a nice clean hole although towards the end it was not cutting as fast as when I started. I think it would get through at least one more cut on porcelain, even if it doesn’t make it through two, it did the job I needed it for. 10 bucks for a hole, i guess thats decent considering the alternative would be some creative tile work.
