HSB, HM Coated 2-Flute Ball

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
· The machining dimension has been improved by improving the wear resistance and setting the rake angle of the ball tip to negative
· The rake angle on the outer circumference side of the ball has been set to weak negative, securing sharpness, providing an excellent processed surface and preventing deflection
