Accupro 31552813 Double Angle Milling Cutter 60 Degree

Product Description

The ACCUPRO 31552813 is a solid carbide double angle milling cutter designed for precision milling of dovetail slots, chamfers, and angular profiles on metalworking machines. It carries a 60-degree included angle with a 1/2-inch cut diameter and a 7/64-inch (0.1090 inch) cutting width. The 1/2-inch straight shank connects directly to standard collet chucks and milling holders. An AlTiN coating provides elevated heat resistance and extended tool life when cutting ferrous and hardened materials. With 6 flutes and a 5/16-inch neck diameter, this cutter maintains rigidity through the cut while providing clearance in deeper pockets and stepped features.

This cutter is suited for job shops, tool rooms, and production machining environments running CNC vertical mills, knee mills, or manual milling machines. It handles angular slot work, chamfer deburring, and dovetail feature creation in steel, stainless, cast iron, and similar hard materials. The 4-inch overall length and 2-7/64-inch neck length allow access to features that require tool extension beyond a standard stub-length reach. Machinists and tool-and-die technicians are the primary users.

Key Features

• 60-degree included angle for standard dovetail and chamfer geometry
• Solid carbide construction for rigidity and wear resistance in hard materials
• AlTiN coating extends tool life at elevated cutting temperatures
• 6 teeth provide a balance of chip evacuation and surface finish
• 5/16-inch neck diameter with 2-7/64-inch neck length for deep-reach applications
• 1/2-inch shank compatible with standard collet and endmill holders

Compatibility

Designed as a direct-mount replacement or new-installation cutter for milling machines fitted with 1/2-inch collet chucks or endmill holders accepting a 1/2-inch straight shank.

Installation Notes

Installation is performed by a machinist or tool-and-die technician. Ensure the machine spindle is fully stopped and the machine is locked out before changing tooling. Seat the shank fully into the holder to the recommended minimum engagement depth before torquing the collet nut or set screw. Inspect the cutting edges and coating for damage before each use; chipped carbide should not be run.
