Union Tool Carbide End Mill Long Neck Ball R1 x Effective Length 18 x φd4 HSLB2020-180 1 piece

Catalog number: HSLB2020-180 Features: ● By machining high-hardness mold materials of 40HRC or more, we have achieved higher machining efficiency, longer life, and higher quality machined surfaces than ever before. ● We have adopted a new HM coat that improves oxidation resistance while maintaining film hardness. ● Stable machining is possible with any of water-soluble and oil-based cutting oils, oil mist, and air blow. ● We have adopted a new HM coat that improves oxidation resistance while maintaining film hardness. ● Stable machining is possible with any of coolant use, mist, and air blow. ● We have adopted a new HARDMAX coat that improves oxidation resistance while maintaining film hardness. ● The rake angle at the tip of the ball is set to negative, improving wear resistance and improving machining dimensions. ● The rake angle on the outer periphery of the ball is set to a weak negative to ensure sharpness, provide a good machined surface, and prevent tipping. Applications: ●Compatible workpiece materials: carbon steel, alloy steel, pre-hardened steel, hardened steel (up to 55HRC) (up to 60HRC) (up to 70HRC), cast iron, copper, titanium alloy, and super heat-resistant alloy.
