Series Expansion – New Items Add to the FP Breaker for Steel Turning

Mitsubishi Materials Corporation, Advanced Materials & Tools Company (President – Shinichi Nakamura, Headquarters: Otemachi, Chiyoda-ku, Tokyo) has added new items to the FP breaker range for steel turning.


The FP breaker insert series is the first choice for high performance finish cutting of low-carbon and alloy steels. The FP geometry provides efficient chip breaking at small depths of cut and prevents chip jamming at high feed rates. A new 1.2 mm corner radius type is now available to allow a wider range of applications.

Features of the FP breaker

1. The optimum corner design and wide chip pocket promotes efficient chip breaking at small depths of cut and prevents chip jamming at higher feed rates.

2. Stable chip curls are produced when finish cutting of softer materials due to the large rake angle and the protrusion geometry of the breaker.

3. The 20°positive rake angle and protrusion are designed to promote low cutting resistance to prevent vibration and tool deflection.
