Union Tool Carbide End Mill Ball R4 x Blade Length 14 x φd8 HB20801400 1 piece

Catalog number: HB20801400 Features: ●By shortening the overall length and reducing the tool overhang length, higher speed and precision machining can be performed. ●By achieving outstanding heat resistance and lubricity, it can cut high-speed steel materials of 65HRC. ●By achieving an unprecedented long life, it can be used in both dry and wet conditions. ●An extra small diameter type has been added to the HB series. ●By adopting a high rigidity specification with two blades/straight blades, it has improved resistance to breakage. ●High R accuracy of ±0.002, outer diameter tolerance of 0/-0.01. Applications: ●Cutting materials: Carbon steel, alloy steel, pre-hardened steel, hardened steel (up to 55HRC), cast iron, copper (wet), super heat-resistant alloy (oil-based cutting oil). ●Compatible cutting materials: Pre-hardened steel, hardened steel (up to 55HRC), copper (wet recommended), carbon steel, alloy steel, cast iron. ●Compatible workpiece materials: Carbon steel, alloy steel, pre-hardened steel, hardened steel (up to 55HRC), cast iron, copper (wet), super heat-resistant alloy (oil-based cutting oil). ●Compatible workpiece materials: Pre-hardened steel, hardened steel (up to 55HRC, up to 60HRC, up to 65HRC), copper (wet recommended), carbon steel, alloy steel, cast iron.
