[Features]
·Combined corner radius shape of shoulder R and bottom R, (1) Cutting chips are thin when milling bottom surface, enabling high-speed feed (2) Minimizing cusp height (uncut portion) during contour milling reduces number of middle finish processes
·Can be regrinded. Please refer to the page dedicated to "regrinding service" for usage procedures, range of services, prices, etc.

● The shoulder R and base R composite radius eliminate the medium finishing process by (1), enabling high-speed feeding due to thin chippings when bottom-surface machining, and by (2), minimizing the cusp height (leftover) when machining lines at the same height.
● The TS coat consisting of a nitride-based composite film with a fully crystalline structure means that it realizes a high oxidation resistance temperature and high hardness. Ideal for high-speed machining and dry machining of anything from raw carbon steel materials through to heat-treated / high hardness steel.
[ ! ] This product has a special groove shape with a performance that may not be reproducible without the use of Misumi dedicated re-grinding.
