Radius cutter for 3-dimensional machining due to helical cutting edges
Unique twisted insert geometries assures secure insert clamping for high stability. Two types of inserts fit one cutter: radius and high efficiency inserts
Applications & Features
Applications
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
