Union Tool Carbide End Mill Radius φ12 x Corner R2 HRRS4120-20-36S 1 piece

Catalog number: HRRS4120-20-36S Features: ●By optimizing the corner R size, machining with a larger pick feed than usual has been achieved. ●Seamless radius shape. ●High hardness materials up to 65HRC can also be machined. ●Outer diameter tolerance: 0/-0.02 (D≦6), -0.01/-0.03 (D≧8). ●By shortening the overall length and reducing the tool overhang length, higher speed and precision machining can be performed. Applications: ●Workpiece material: Pre-hardened steel, hardened steel (up to 55HRC) (up to 60HRC) (up to 65HRC), cast iron. Specifications: ●Blade diameter (mm): 12 ●Corner radius (mm): 2 ●Blade length (mm): 12 ●Total length (mm): 75 ●Shank diameter (mm): 12 ●Effective length (l): 36 ●Effective shank length (H): 35.5 ●Neck diameter (φd1): 11.82 ●Outer diameter (φD): 12 ●Made in an ISO9001 certified factory ●Made in an ISO14001 certified factory ●HARD MAX: HARD MAX coating ●Twist angle 45° ●4-blade high-efficiency radius end mill HRRS Material/Finish: ●Ultra-fine particle alloy (Super MG) ●Super-hard fine particle alloy (Super MG) Note: ●The shank taper angle is a guideline. ●If you are concerned about interference with the workpiece, be sure to measure it and check it. Be careful of contact between the shank and the workpiece.
