Works great on mirror

I used two sets to drill some holes in a 1/4 inch thick mirror so I could put a light in the center of the mirror can install . No signs of wear after a few holes. I had a garden hose hooked up to ensure a steady flow of water. The only issue with the mirror was a small chipping of the coating on the back, but I don't blame bits for that, it's my technique. I would say for the price they are hard to beat.

Pros
  • Attention: The diamond hole saw is mounted on a professional drill or electric drill, bench drill. 800-1000 RPM or so, you'll need to add water cooling holes as you work
Cons

Saves time and nerves

I make crafts on Pinterest that involve drilling holes in china, glassware, and ceramics. I used my dremel with a diamond cutting attachment and a drill bit with the appropriate attachments and it took me 45 minutes or more to make the holes. That really got me off my projects. I bought them and BAM! The intuitive design means you can just pop it into your drill and get to work. Very fast, for sure. I can't rate the durability as I only used it yesterday. I'll update along the way.

Pros
  • Perfect design: Mounted along the drill, these glass hole saws make it easier for cooling water to flow in and remove chips and other particles when drilling. Makes drilling easier
Cons
  • No productivity

Got the job done with power tools and hand tools

Ordered these bits to cut a hole in the tile for the shower screen. As another customer mentioned, bits don't last long, but even for one-time use, you can't beat the price. I only bought 1 bit from a store twice the price but I had to return it because it didn't fit. Instead, I ordered this set of 15 sizes. I "sacrificed" a few small ones for practice that I knew I wouldn't need and also to start carving - I didn't know how long they would last. Once I felt confident I used the largest size (I
