Union Tool Carbide End Mill Ball R6 x Blade Length 18 HFB4120-1800S 1 piece

Catalog number: HFB4120-1800S 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. ● Reducing unnecessary tool protrusion allows for higher precision machining. ● Improves machining efficiency when combined with a shrink fit holder. 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): 6 ●Blade length (mm): 18 ●Total length (mm): 60 ●Shank diameter (mm): 12 ●Surface treatment: HARD MAX coating ●Effective shank length (H): 31.5 ●Twist angle 40° ●Made in an ISO9001 certified factory ●Made in an ISO14001 certified factory ●HARD MAX: HARD MAX coating ●4-blade high-efficiency ball end mill HFB Material/Finish: ●Ultra-fine 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.
