Product Info

FSF and FSF-P turning inserts help reduce cutting force, ensure precise surface finishes, and significantly extend tool life — ideal for small parts and difficult-to-machine materials.

FSF and FSF-P are advanced positive chip breaker inserts specially developed for high-precision external turning of small, complex parts such as medical devices, aerospace components, and stainless steel (SUS304). These inserts minimize burr formation, reduce chip entanglement, and support stable, continuous machining.

The FSF-P variant features a polished surface to further reduce built-up edge formation, enhancing cutting stability and minimizing downtime due to insert changes.

■ Key Features
・ Sharp 25° rake angle lowers cutting resistance and enhances surface quality.
・ Multi-stage chip breaker groove effectively manages chips at various cutting depths, reducing chip jamming.
・ Polished surface on FSF-P reduces chip adhesion, ideal for tough materials like stainless steel, titanium, and heat-resistant alloys.
・ High dimensional accuracy minimizes burrs and supports ultra-smooth finishes.
・ Certified as JTA ECO PRODUCT, contributing to environmentally friendly manufacturing.

■ Recommended Applications
・ External turning of stainless steel (e.g., SUS304) and heat-resistant alloys.
・ Production of aerospace and medical components requiring strict surface finish standards.
・ High-precision small diameter bar turning on Swiss-type CNC lathes.

■ Results from Actual Use
In actual machining tests with SUS304, the number of workpieces per insert increased from 150 to 750 while maintaining excellent surface finish and greatly reducing burrs and machine downtime.
