Accupro 31688039 Double Angle Milling Cutter 60 Degree

Product Description

The ACCUPRO 31688039 is a double angle milling cutter designed for precision grooving, chamfering, and dovetail slot work on machining centers and manual mills. Built from solid carbide, this cutter delivers the rigidity and edge retention needed for tight-tolerance cuts in ferrous and non-ferrous materials. It features a 60-degree included angle, a 3/16-inch cutting diameter, and a 0.055-inch cutting width. The uncoated solid carbide construction makes it suitable for applications where coating buildup in small-geometry cutters could affect dimensional accuracy. Four cutting teeth provide a balance of chip clearance and finish quality in fine detail milling operations.

This cutter is used in tool and die, mold making, aerospace component machining, and general precision metalworking applications where a consistent angled profile is required. The 3/16-inch shank diameter is compatible with standard collet systems commonly found on CNC machining centers and manual knee mills. The 0.555-inch neck length provides clearance for moderate-depth grooving operations without requiring extended-reach tooling. It is typically installed and operated by machinists and toolmakers working to close dimensional tolerances.

Key Features

• 60-degree included angle for chamfering, V-grooving, and dovetail profiling
• Solid carbide construction provides rigidity and edge retention in fine-geometry applications
• Uncoated finish suited for applications where coating thickness would affect small-diameter accuracy
• 4-flute design balances chip evacuation with surface finish quality
• 3/32-inch neck diameter allows clearance in confined milling areas
• 2-inch overall length compatible with standard collet and toolholder setups

Compatibility

Designed for use with standard 3/16-inch collet systems on CNC machining centers and manual milling machines where double angle cutters with a 3/16-inch shank diameter are specified.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer guidelines for collet torque and runout tolerance. Confirm collet condition and seating before use, as runout in small-diameter carbide tools accelerates edge wear and can cause chipping. Inspect the cutting edges under magnification before each use. Do not exceed the recommended depth of cut or feed rate for the cutter diameter and material combination being machined.
