Radius cutter for profile milling of complex parts

Innovative and safe anti-rotation system, featuring FIX insert location provides highly rigid clamping

Applications & Features

Applications

Shoulder milling RFace millingSlotting RPocketingRampingProfilingHole enlargingCoolant hole

Features

1. Anti-rotation system with rigid clamping

• Secure insert seating on protrusion of cutter body.
• Cutting force pushing insert towards pocket, resulting in rigid clamping.

2. Round insert with 6 indexes

• No need to take off screw to change cutting-edges.

3. High-cutting speed Vc up to 300 m/min (984 sfm)

Inserts & Grades

Inserts

RPMT-MJ / -ML

  • The unique insert fixation in the pocket allows up to 6 indexes.
  • Two types of chipbreakers are available:
    • MJ: General purpose machining
    • ML: Low cutting force machining
Grades

AH725

  • For general purpose milling
  • Provides high reliability in steel and cast iron machining
  • Highly versatile grade with excellent wear and chipping resistance

AH130

  • For general stainless steel milling
  • Reduces crater and notch wear
  • Provides exceptionally reliable milling

AH4035

  • Ideal grade for high chromium content stainless steels
  • Newly developed grade with exceptional balance of wear and chipping resistance
  • Drastically reduces flank wear and chipping when machining stainless steels
