Vacuum Brazed Diamond Bits


Vacuum brazed diamond hole saws for drilling clean, accurate holes in porcelain tile, glass tile, ceramic tile, marble, granite, slate, limestone, terrazzo, quartz and similar materials.

  • Produce fast, chip-free holes that result in a first-class job.
  • Life expectancy is 20-30 times longer than conventional diamond plated bits.
  • Use with variable speed drills (300-1,000 RPM) for best results.
  • Vented barrel (side hole) is included for cooling and water flow.
  • Not for use with hammer drills or roto-hammers.
  • May be used wet or dry.
  • Made in the USA.

Drilling Tip: Blazer bits may be used for dry drilling. However, spraying water on the drilling surface helps keep the bit cool and reduces friction, producing a better result.
