Chip breaker
Extracted from the Wikipedia article Chipbreaker.
A chipbreaker or chip breaker is a contour just behind the cutting part of a cutting tool that directs away any chips that are generated. Metal chips are hot, sharp, and can spin at high speeds, especially if they get caught in machinery. Breaking up the chips into smaller pieces is an important safety feature since long chips that get caught in people and machinery can lead to serious workplace accidents. It can also damage tools, workpieces and machinery, and make removal of the finished product more difficult.
