Description of GME-SPM200 Small Diameter End Mill
The GME-UPR200 small-diameter end mill is optimized for small-diameter deep processing. The diameter range is 0.5-6mm, the blade length can reach 10 times the diameter, and it supports high-speed processing. Special coating technology reduces wear and improves heat resistance; the multi-blade design takes into account cutting efficiency and precision, and is suitable for difficult-to-process materials such as titanium alloys and hardened steel. Optional internal cooling models, effective chip removal, and cooling are a reliable choice for precision parts processing.

Features of GME-SPM200 Small Diameter End Mill
●Suitable for deep groove micromachining of carbon steel, alloy steel, hardened steel, copper, aluminum alloy, and other materials (hardness ≤ HRC55) in the precision mold industry.
●High-precision blade diameter accuracy, ball head profile, R arc profile, and shank accuracy (h5).
●High-performance AlCrSiN nano coating is used, which is resistant to high temperature and wear.
●Special angle and long air avoidance design.
