Head-changeable drill for drilling large holes

Unique clamping concept and two effective cutting edges on the drill head provide excellent hole quality and high productivity

Applications & Features


1. Two effective cutting edges

• The drill head with two effective cutting edges provides high productivity and reliability.

2. Unique clamping system

• The drill head change is possible without removing the drill body from the tool holder or the spindle, eliminating re-adjustments.
• Asymmetric shaped drill head not only secures stability in heavy machining but also error-proofs drill head installation.
• The drill body has a wide supporting area for the drill head for rigid insert clamping.

Inserts & Grades


SMP (ø20 – ø41 mm)

  • General purpose type

SMF (ø20 – ø41 mm)

  • Provides greater resistance to radial forces, improving machining stability during the drilling of irregular surfaces or workpieces with low rigidity
  • Coated with wear resistant PVD grade, AH9130


  • P15 – P30 / M15 – M30 / K25 – K30 / S15 – S25

  • Good balance between wear and chipping resistance

  • Suitable for machining steel and stainless steel under general cutting  conditions


  • P15 – P35 / M25 – M35 / K10 – K25 / S15 – S30
  • High wear resistance
  • Designed for drilling various materials
