  • 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.
