Union Tool 4-blade taper neck radius end mill, outer diameter 4 x corner radius R1 x neck taper angle 1.9° x blade length 4 x neck length 30 HTNRS4040-103038 1 piece

Catalog number: HTNRS4040-103038 Features: ●26-blade taper neck radius end mill for machining high-hardness materials. ●The corner R shape that smoothly connects from the tip to the outer circumference reduces cutting resistance, and the unequal division shape suppresses chatter vibration. ●Realizes stable machining and high-quality machined surfaces even in deep engraving. ●The use of HARDMAX coating ensures a long life when machining high-hardness materials. ●Compatible with all coolants. Uses: ●Compatible workpiece materials: Pre-hardened steel, hardened steel (up to 55HRC) (up to 60HRC) (up to 65HRC), cast iron Specifications: ●Blade diameter (mm): 4 ●Corner radius (mm): R1 ●Blade length (mm): 4 ●Total length (mm): 70 ●Shank diameter (mm): 8 ●Number of blades (pieces): 4 ●Surface treatment: HARD MAX ●Effective length (mm): 6 ●Number of blades: 4 ●Twist angle: 45 ●Compatible workpiece materials: Pre-hardened steel, hardened steel (up to 55HRC) (up to 60HRC) (up to 65HRC), cast iron Material/Finish: ●Super MG Caution: ●The shank taper angle is a guideline. ●If interference with the workpiece is required, be sure to measure it and check it. ●Please be careful of contact between the shank and the workpiece.
