### ⭐⭐⭐⭐⭐ Worked great on granite countertop
*by J***N on November 11, 2025*

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.

### ⭐⭐⭐⭐⭐ Good tool
*by K***R on January 6, 2026*

Worked perfectly.

### ⭐⭐⭐⭐⭐ Great little drill for the price...worked well on standard thickness shower wall tiles.
*by T***L on November 25, 2025*

We pre-drilled a board that we laid on top of the tile that we wanted to drill, attaching it lightly with 4 small clamps. We then layed the tile on top of another board for support underneath. We poured water over the drilling location continuously while slowing drilling with very little downward pressure. Be patient and it'll come out fine. Be sure to follow the instructions and remove the center point drill onces the main drill section makes a little contact with the tile. (Note: There are two holes in the wood guide simply because the first one was too large and would have allowed the bit to wander too much).
