Applications & Features

Applications

Profiling Pocketing Shoulder milling R Face milling Slotting R Hole enlarging

Features

1. Multi-functional cutter body with superior reliability

• Two types of inserts fit one cutter: radius and high efficiency inserts.
• Secure insert clamping to prevent insert from moving during machining.

2. High-feed insert with greater depth of cut

• Smooth chip control enables stable machining.

3. Radius insert with high reliability

• Insert cross section is designed to be 2 times as large as that of a round insert.
• Excellent chip evacuation in various applications.
