Z Series High Hardness & High Precision Mold End Mill — Z4E08020

A 0.2 µm ultra-fine grain carbide substrate combines extremely high hardness with toughness. Reinforced tool geometry and whole-process precision quality control ensure excellent cutting performance. The RZ coating, a new-generation upgrade of conventional AlTiN, offers high heat and wear resistance, suppressing edge chipping during hardened-steel machining and extending tool life. Verified series test: Ø3×50 on S136 (HRC52+), cutting speed 226.08 m/min, 12,000 rpm, feed 2,000 mm/min, 0.08 mm/tooth, finishing. Exhibited model: Z4E08020, Ø8 × 20 mm flute length, 4 flutes, 60 mm overall length. Series range Ø0.2–20 mm.
