Chip Breaker Guide

Chipbreaker Cutting Edge Application Description
MA Aluminium Optimal cutting edge, high positive rake and buffed surface prevents built up edge and smooth chip flow in aluminium machining.
ML Stainless Steel / HRSA's Chip breaker with low cutting load is ideal for machining hard‑to‑cut materials such as stainless steel, titanium, inconel and hastelloy.
MF Light Cutting / Finishing / Soft Steel Chip breaker with low cutting load and sharper cutting edge. Excellent for finishing operations, general milling of soft steels and also ideal for low power machines due to low cutting resistance.
MM General Machining Optimal for milling in general machining conditions.
