Review: Outstanding quality and fast cutting! - I have a handyman business and I had a customer that needed an outlet mounted in a quartz countertop. I was planning on buying a hole saw at HD and scoffed at the price since I'd likely only need the saw for an occasional job. I took a chance on this saw and I was pleasantly surprised at how well the pilot bit worked and how well the hole saw cut. I made a water dam out of some plumbers putty and it kept the saw cool. After using the saw, I cleaned and inspected and it looks brand new.
Review: Worked great on granite countertop - I have only used once on a piece of granite countertop. It appears to have plenty of life for future use. It cut easily and fast with water. The thickness helps to go all the way through entire piece of granite - it was close. Worth the money.

I have only used once on a piece of granite countertop. It appears to have plenty of life for future use. It cut easily and fast with water. The thickness helps to go all the way through entire piece of granite - it was close. Worth the money.

### ⭐⭐⭐⭐⭐ Works great
*by J***S on January 20, 2026*

After I installed the tile, I cut a hole in the tile for the toilet drain. The cutter did an excellent job. The edges of the tile were clean.
