About This Product

These Monster brand diamond bits are made with vacuum brazed technology. They are very aggressive in that diamonds are exposed entirely. They last longer than electroplated diamond core drill bits because diamonds will not drop while drilling. They are ideal for drilling granite, marble, quartz, glass, porcelain, ceramic tiles as well as concrete. Life of these bits vary on material and conditions of use.


  • Shank size is 1/2 in. fits most electric drills
  • Total length for the bit is 3 in. with 1.5 in. drilling depth
  • 50/60 grit diamond
  • Wet use recommended for longer life and faster cutting
  • Most suitable for drilling tiles
  • Optimal speed 2000 - 4500 RPM
