  • High flow spiral design bit body for fastest removal rate
  • Straight shank for a standard drill chuck, end of the shank is chamfered to allow easy and firm holding
  • Special bronze SST heat and surface treatment
  • Good for drilling stainless steel, cast iron, and titanium alloy. Do not use on glass, ceramic, high-carbon steel, or heat-treated steel.
