TSC series carbide long neck square end mill, 4-flute / long neck model

Caution
Product Description
[Features]
·Demonstrates high performance in processing general steel, SUS304, and heat-treated steel (up to 50 HRC)
·Can select optimal body length for processing deep parts of workpiece
·Optimal for machining in low to medium rotation range due to the 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

More Information

● The ideal under-neck length can be selected for workpiece machining in deep areas.
● It has a TS film coating with much greater oxidation resistance and hardness than conventional films, yielding a longer operational life and is ideal for high speed machining / dry machining.
