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

Drilling

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

Inserts

SMP (ø20 – ø41 mm)

  • General purpose type

SMF (ø20 – ø40 mm)
