HM Coated 2-flute, Long Neck Ball HSLB

UNION TOOL

[Features]
· Compared to conventional products, this model achieves higher machining efficiency, longer service life and higher quality machining of hard mold materials at 40 HRC or more.
· New HARDMAX coating adopted to maintain film hardness while improving oxidation resistance
· Provides stable processing for water-soluble/oil-based cutting oil, oil mist, and air blow
