U Series High Performance Universal End Mill — U4E10025

A 0.4 µm sub-micron grain carbide substrate balances toughness and wear resistance. The unequally divided (variable pitch) anti-vibration structure together with an oversized U-shaped flute greatly improves chip evacuation. The RU coating, a new-generation upgrade of conventional TiAlN, provides high wear resistance and lubricity, preventing edge chipping and chip adhesion. Verified test: H13 (HRC48–52), cutting speed 226.08 m/min, 7,200 rpm, feed 3,000 mm/min, 0.2 mm/tooth, finishing. Exhibited model: U4E10025, Ø10 × 25 mm flute length, 4 flutes, 75 mm overall length. Series range Ø1–20 mm.
