New chip breaker geometry for fine boring

New solution for machining long-chipping steels

In metal machining, chip formation plays a key role in process reliability, tool life and surface quality. Controlled chip formation is particularly crucial to the fine machining of unalloyed, alloyed and stainless steels.

The benefits for the user are clear: optimum chip removal, low heat development and very high process reliability.
The technology contributes to the efficiency of manufacturing and ensures the high quality of
the machined workpieces. Less machine downtime, less machine wear and high dimensional
accuracy translate into tangible cost benefits.
MAPAL has put its many years of experience in developing chip breakers into a solution with
series production maturity, available from stock with defined geometries and coatings from autumn 2025.
