Review on Vacuum Brazed Diamond Core Drill Bits Kit 2-1/2" (65Mm) – Ideal For Porcelain, Ceramic, Marble, Granite, Stone, Brick, And Glass With 5/8-11 Thread by John Maynard

Good for getting a nice neat job

I got this because I'm going to do some tile work in my bathroom. Using this will give a nice clean look instead of using nippers and a coated hacksaw blade. Remember the tool do the work otherwise you will just knock the diamonds off. I actually looked at this under a microscope and it doesn't have as many diamonds as it looks to have. Most of the sparkle is from the brazing

Pros
  • Not for thick materials but great for tile.
Cons
  • The diamond coating may wear off quickly after several uses
