Features & Benefits

• Tri Margin Design

  
  

  • Improved hole stability over two flute designs
  • Superior surface finish, roundness, and hole cylindricity
  • Unsurpassed hole size control
• Self Stabilizing Point

  
  

  • Pyramid design stabilizes the drill on contact with the workpiece
• Open Flute Structure
  • Efficiently transports chips while maintaining strength at high feed rates
• Sculpted Gash
  • Allows chips to easily flow away from the drill center
  • Reduced cutting forces over competitive three-flute designs
• Minimal Margin Design
  • Reduces frictional heat generated by excessive margin contact with the work piece
  • The parallel design maintains contact-width as margin wears for performance consistency
