  • Special Hi-Molybdenum tool steel.
  • 135° split point for fast penetration and accurate starting without center punch.
  • Precision-ground point, flutes, body, clearance, and drill diameter for the ultimate in accuracy and performance.
  • Body and clearance are gold surface treated for maximum lubricity.
  • Heat treated at 2185°F and then nitro-carburize finished at 950°F to be measurably harder than high-speed steel.
  • Space age nitro-carburized steel withstands substantially higher drilling temperatures while maintaining sharpness.
  • Recommended for use in work hardening grades of stainless steel and other hard metal drilling applications.
