[Features]
-Demonstrates high performance in machining general steel, EN 1.4301 Equiv. (sintered) and heat-treated steel (up to 50 HRC)
-Adopting the 3-flute shape, it is resistant to chatter and can operate from plunging to grooving without steps
-The unique shape of the chip groove enables grooving with a depth of cut equivalent to that of a 2-flute tool
-Comparable to 30° helix angle square shoulder cutters, 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 cutters
-The coating has high oxidation resistance and hardness and achieves long life. Effective in high-speed machining and dry machining as coating properties
-Can be reground. Please refer to the "Regrinding Service" page for application procedures, range of services, prices, etc.

More Information

● 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.
● Has a 3-flute shape to be strong against chatter and is capable of stepless grooving.
● 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.
