Accupro 12177370 Corner Radius End Mill 6mm 2 Flute Altin

Product Description

The ACCUPRO 12177370 is a solid carbide corner radius end mill designed for precision milling operations in metalworking and machining environments. Built from micrograin solid carbide and coated with AlTiN (aluminum titanium nitride), it delivers high heat resistance and extended tool life in ferrous and hardened materials. The 6 mm cutting diameter pairs with a 1 mm corner radius that reduces stress concentrations at part edges and corners. With a 30-degree helix angle and two right-hand spiral flutes, this end mill produces efficient chip evacuation and a clean finish. Installed by machinists and CNC operators in job shops and production environments.

This end mill is suited for finish and semi-finish milling of slots, pockets, and contoured profiles in steel, stainless, cast iron, and similar hard materials. The centercutting design allows plunge entry, expanding its range of applications. The extended reach configuration, with an 11 mm reach length, allows access to recessed features and deep-wall geometries without requiring a longer overall tool assembly. Single-end construction means the tool is replaced rather than flipped when worn.

Key Features

• AlTiN coating provides oxidation resistance and hardness at elevated cutting temperatures
• Micrograin solid carbide substrate for rigidity and wear resistance in demanding cuts
• 1 mm corner radius reduces tool chipping and part edge stress
• Centercutting capability allows direct plunge milling
• 30-degree helix angle promotes smooth chip flow and reduced cutting forces
• Extended reach design accesses recessed pockets and deep-wall features

Compatibility

Designed as a direct-fit replacement for standard 6 mm shank tool holders used in CNC machining centers and manual milling machines that accept ER collets or comparable 6 mm round shank tooling.

Installation Notes

Installation is performed by machinists using an appropriate collet chuck or end mill holder sized for a 6 mm shank diameter. Confirm holder runout is within tolerance before cutting to preserve the corner radius geometry. Follow machine manufacturer torque specifications for collet nuts. Inspect the cutting edges and corner radius under magnification before each use to confirm no chipping is present.
