[Features]
·Demonstrates high performance in processing general steel, SUS304, and heat-treated steel (up to 50 HRC)
·The unique chip gullet shape enables groove cutting with a depth of cut equivalent to that of a 2-flute cutting tool
·Compared to 30° helix angle square end mills, both rotation and feed are more than twice as fast
·The 45° helix angle makes it ideal for high-speed machining compared to general-purpose 30° helix angle
·It has coating with high oxidation resistance and high hardness, and achieves a long service lifespan. Effective in high-speed machining and dry machining as coating properties
·Can be regrinded. Please refer to the page dedicated to "regrinding service" for usage procedures, range of services, prices, delivery times, etc.

● It has a TS film coating with much greater oxidation resistance and hardness than conventional films, resulting in a longer operational life and ideal for high speed machining / dry machining.
● The unique tip pocket shape allows for the cutting of grooves to be achieved with 2 flutes in parallel at the cutting depth.
● Compared to 30° twisted square end mills, both rotation and feed capacity are more than double for higher speed machining.
