  • Made of special hi-molybdenum tool steel.
  • Heat treated at 2185 Degrees Fahrenheit and then nitro-carburized at -950 degrees 
  • The bits are measurably harder than standard high-speed steel
  • Feature a 135 split point for faster penetration and accurate starting without a center punch
  • The body and clearance of this bit are “gold surface" treated for maximum lubricity
  • Designed for drilling in harder steels such as stainless
  • Less brittle than a cobalt bit, so you will not have the problem of chipping
