Accupro 12177336 Corner Radius End Mill 1.2 Mm 2 Flute

Product Description

The ACCUPRO 12177336 is a solid carbide corner radius end mill designed for precision milling in tight-tolerance applications. It features a 1.2 mm cutting diameter with a 0.1 mm corner radius, a 2-flute right-hand spiral configuration, and a 30-degree helix angle. The tool is coated with AlTiN (aluminum titanium nitride) for improved heat resistance and tool life at elevated cutting speeds. Micrograin carbide construction provides rigidity and edge retention in hard and abrasive workpiece materials. This end mill is used by machinists and tool-and-die professionals working on CNC machining centers and milling machines.

This end mill is suited for small-feature milling in dies, molds, and precision components where a corner radius is required to reduce stress concentration. The centercutting design allows plunge entry into the workpiece. Extended reach geometry, with a 15 mm reach length and 6 mm shank diameter, provides access to recessed features without sacrificing rigidity. It is a single-end tool intended for right-hand cutting direction on standard CNC and manual milling setups.

Key Features

• 1.2 mm cutting diameter with 0.1 mm corner radius for small-feature, reduced-stress milling
• AlTiN coating for high heat resistance and extended tool life in hard materials
• Micrograin solid carbide construction for rigidity and sharp edge retention
• Centercutting design allows direct plunge entry
• 30-degree helix angle and right-hand spiral flute for efficient chip evacuation
• Extended reach with 15 mm reach length for access to recessed part features

Compatibility

Designed as a replacement or standard tooling selection for CNC machining centers and manual milling machines accepting a 6 mm straight shank, in applications requiring a corner radius end mill at 1.2 mm diameter.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Ensure the machine spindle is fully stopped and the tool holder is clean and free of debris before seating the shank. Verify runout with a dial indicator after installation; excessive runout at this diameter will accelerate tool wear and affect corner radius tolerance. Follow the machine manufacturer's torque specifications for the collet or tool holder used.
