Accupro 31577661 Double Angle Milling Cutter 60 Deg 5/16 in

Product Description

The ACCUPRO 31577661 is a double angle milling cutter designed for precision grooving, chamfering, and angular milling operations on machining centers and manual mills. Built from solid carbide, it delivers the rigidity and wear resistance required for cutting ferrous and non-ferrous materials at tight tolerances. The included angle measures 60 degrees, the cut diameter is 5/16 inches, and the cutting width is 0.072 inches. With a 5/16-inch shank diameter and an overall length of 2.5 inches, this cutter fits standard collet and end mill holders used in production and toolroom environments. Licensed machinists and CNC operators are the primary installers.

This cutter is suited for light to medium milling work requiring precise angular profiles. Common applications include dovetail prep cuts, V-groove forming, and deburring operations on aluminum, steel, brass, and engineering plastics. The uncoated solid carbide construction makes it a practical choice in dry or mist-cooled cutting conditions where a bare carbide edge is preferred for edge sharpness and regrindability. The 6-tooth geometry supports smooth chip evacuation in shallow angular cuts typical of toolroom and production floor use.

Key Features

• 60-degree included angle for standard V-groove and chamfer profiles
• Solid carbide construction for rigidity and wear resistance
• 0.072-inch cutting width for narrow, precise angular slots
• 6 teeth for smooth finish and efficient chip removal
• Uncoated finish — suitable for regrinding and dry-cut applications
• 3/16-inch neck diameter with 0.447-inch neck length for clearance in confined cuts

Compatibility

Designed as an OEM-style replacement and standard toolroom cutter compatible with 5/16-inch collet chucks and end mill holders on CNC machining centers and manual knee mills.

Installation Notes

Installation is performed by a qualified machinist or CNC operator. Power down and lock out the spindle before mounting or removing the cutter. Seat the shank fully in the collet or end mill holder and torque the retention hardware per the machine tool manufacturer's specifications. Inspect the cutting edges for chips or cracks before each use — do not run a damaged carbide tool.
