Accupro 31777238 Double Angle Milling Cutter 90 Deg

Product Description

The ACCUPRO 31777238 is a double angle milling cutter designed for precision angle milling operations in metalworking and machining applications. Built from solid carbide, it delivers the rigidity and wear resistance required for consistent performance in production and toolroom environments. The cutter features a 90-degree included angle, a 5/16-inch cutting diameter, and a 1/8-inch cutting width. The 5/16-inch shank provides a direct, secure connection to standard milling machine collets and holders. With 6 teeth and an uncoated carbide body, this cutter is suited for machinists and tool-and-die professionals who need reliable geometry and sharp edge retention in ferrous and non-ferrous materials.

This cutter is used in vertical and horizontal milling setups where chamfering, dovetail preparation, or angular groove cutting is required. The 3/16-inch neck diameter and 1/2-inch neck length provide clearance in deeper pockets and restricted-access features. The 2-1/2-inch overall length makes it compatible with standard collet chucks and end mill holders in most knee mills, CNC machining centers, and manual milling machines. It is typically selected for precision toolroom work, fixture fabrication, and production machining where controlled angular geometry is critical.

Key Features

• 90-degree included angle for standard chamfering and angular milling operations
• Solid carbide construction for superior hardness and wear resistance compared to HSS
• 5/16-inch cutting diameter with 1/8-inch cutting width for precise, narrow angular cuts
• 6-tooth design provides a balance of chip clearance and cut finish quality
• 3/16-inch neck diameter allows access to restricted features and deeper pockets
• Uncoated finish suitable for a wide range of workpiece materials without coating compatibility concerns

Compatibility

Designed for use in standard milling machines and CNC machining centers equipped with collet chucks or end mill holders accepting a 5/16-inch shank diameter.

Installation Notes

Installation is performed by qualified machinists. Secure the shank fully into a collet or end mill holder and tighten to the toolholder manufacturer's specified clamping procedure before operation. Ensure the spindle is fully stopped and the machine is powered down before installing or removing the cutter. Inspect the cutting edges for chips or damage before each use, as carbide is brittle and sensitive to improper handling or interrupted cuts without proper setup.
