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 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 is a great hole saw. I used it to install an instant hot water dispenser for the kitchen sink. I had to cut a 1-3/8" hole in the 1" thick quartz countertop. I followed the directions (keep water on the blade) and it cut perfectly. I stopped the drill every minute or so to drop more water into the cut. I think the hole saw was a great value and I highly recommend it.

It's a cheap saw, but for the money it's a good value. I used it to drill through tile and 3 inches of concrete under it. Worked well.

Worked great. Got me out of a pinch cutting out around a shower diverter on one of our jobs. Clean cut. Pilot bit was better than I thought for a cheap bit. Just make sure you use plenty of water. Will order again once this one taps out.

The drill bit worked very good drilled through very quickly.

I needed to add a hole in my garage sink for a soap dispenser. The sink is an old porcelain over cast iron sink. I thought I would have to cut the pilot hole with a different drill bit and then use this hole saw. Turns out this went clean through with no issues at all. The pilot bit provided cut right through the porcelain and iron, as did the diamond saw.I'm sure I will have more uses for this saw and it will work well, but I needed this one job done and it worked perfectly. For the price, even if I never use it again, I'm happy.

Needed one 2.5” hole and could not justify spending over $50 on a Milwaukee hole saw. I gave this one a try and it worked great just go slow and use a little water

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.
