Applications & Features

Applications

Drilling

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.
