Accupro 12177384 Corner Radius End Mill 12mm 2 Flute Carbide

Product Description

The ACCUPRO 12177384 is a solid carbide corner radius end mill designed for precision milling operations in metalworking and machining environments. It features a 12 mm cutting diameter with a 1.5 mm corner radius, producing a controlled blend between the side wall and floor of a cut while reducing corner chipping and stress concentration. The 2-flute geometry and 30-degree helix angle promote efficient chip evacuation. An AlTiN coating provides elevated heat resistance and extended tool life in high-speed applications. This tool is installed and run by machinists and CNC operators working in job shops, production facilities, and tool rooms.

This end mill is suited for profiling, slotting, and contouring operations on ferrous and hardened materials where a radiused corner is required. The centercutting design allows plunge entry. The extended reach configuration, with a 25 mm reach length and 83 mm overall length, provides clearance for deeper workpiece features without requiring a longer reach adapter. Right-hand cutting and right-hand flute spiral are standard for conventional CNC spindle rotation.

Key Features

• 1.5 mm corner radius reduces stress concentration and corner chipping at the cutting edge
• AlTiN coating provides heat resistance for high-speed machining of ferrous materials
• Centercutting geometry allows direct plunge entry into the workpiece
• 30-degree helix angle promotes smooth cutting action and chip evacuation
• Extended reach design with 25 mm reach length accommodates deeper workpiece features
• Micrograin solid carbide construction for rigidity and wear resistance

Compatibility

Designed as a direct-fit replacement or standard tooling selection for CNC machining centers and manual mills accepting a 12 mm straight shank with right-hand rotation.

Installation Notes

This tool is installed by machinists using a collet chuck or end mill holder sized for a 12 mm shank diameter. Verify runout and tool holding torque per the machine tool manufacturer specifications before operation. Confirm spindle rotation direction is right-hand before engaging the cut. Inspect the cutting edges for chips or coating damage before each setup.
