Union Tool Carbide End Mill Ball R1 x Blade Length 3 HFB4020-0300 1 piece

Catalog number: HFB4020-0300 Features: ● Achieves both high-efficiency high-feed machining and grinding-free machining. ● Despite having four blades, the wide chip pocket achieves good cutting discharge. ● By shortening the overall length and reducing the tool protrusion length, higher speed and high precision machining can be performed. ● Outer diameter tolerance: 0/-0.02. ● Compatible with shrink-fit holders. ● By reducing unnecessary tool protrusion, higher precision machining is possible. ● By combining with a shrink-fit holder, machining efficiency is improved. Applications: ● Workpiece: Hardened steel. (up to 55HRC) (up to 60HRC) (up to 70HRC) ● Compatible workpiece: Hardened steel (up to 55HRC, up to 60HRC, up to 65HRC) ● Compatible workpiece: Pre-hardened steel, hardened steel. (up to 55HRC) (up to 60HRC) (up to 65HRC) Specifications: ●Ball radius (mm): 1 ●Blade length (mm): 3 ●Total length (mm): 50 ●Shank diameter (mm): 4 ●Surface treatment: HARD MAX coating ●Twist angle 40° ●Made in an ISO9001 certified factory ●Made in an ISO14001 certified factory Material/Finish: ●Ultrafine particle alloy (Super MG) Note: ●The shank taper angle is a guideline. ●If interference with the workpiece is required, be sure to measure it and confirm.
