Accupro 12177320 Corner Radius End Mill 0.6 Mm 2 Flute

Product Description

The ACCUPRO 12177320 is a single-end corner radius end mill engineered for precision milling in demanding metalworking applications. Built from micrograin solid carbide and coated with AlTiN, it delivers heat resistance and wear life needed when cutting hard ferrous alloys and stainless steels at elevated speeds. The cutter measures 0.6 mm in diameter with a 0.05 mm corner radius, a 0.6 mm length of cut, and a 50 mm overall length. The 4 mm shank diameter and 12 mm reach length make it well suited for tight-clearance work where extended reach is required. Centercutting geometry allows direct plunge entry without a pre-drilled pilot hole.

This end mill is intended for CNC machining centers, micro-milling operations, and die and mold work where fine detail and tight tolerances are critical. The right-hand spiral flute design with a 30-degree helix angle promotes efficient chip evacuation in slotting, profiling, and ramp milling. It is a strong fit for tool and die shops, aerospace component machining, and medical device manufacturing where small-diameter, high-precision cutters are routine. The extended reach configuration allows access to deep cavities and stepped pockets not reachable with standard-reach tooling.

Key Features

• 0.05 mm corner radius protects edge integrity and reduces stress concentration at part corners
• Micrograin solid carbide substrate provides rigidity and dimensional stability at small diameters
• AlTiN coating improves oxidation resistance and extends tool life in high-temperature cutting conditions
• Centercutting design supports direct plunge milling without a pre-drilled hole
• 30-degree helix angle with right-hand spiral fluting promotes clean chip evacuation
• Extended reach with 12 mm reach length for deep-cavity and stepped-pocket access

Compatibility

Designed as a drop-in replacement-style cutter for CNC machining centers and manual mills equipped with a 4 mm collet or matching tool holder accepting a 4 mm shank diameter.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the machine spindle and collet are fully powered down and locked out before inserting or removing the tool. Use a collet sized to the 4 mm shank diameter and verify runout with a dial indicator before commencing cuts. At this diameter, excessive overhang beyond the specified reach length significantly increases deflection risk and should be avoided.
