Accupro 31553670 Double Angle Milling Cutter 60 Degree

Product Description

The ACCUPRO 31553670 is a double angle milling cutter designed for precision dovetail slotting, chamfering, and angular groove milling on machining centers and manual mills. Built from solid carbide with an AlTiN coating, it handles hard ferrous materials and high-temperature alloys at elevated cutting speeds. The included angle measures 60 degrees, the cut diameter is 1/2 inch, and the cutting width is 7/64 inch (0.1090 inch). With 6 teeth and a 4-inch overall length, this cutter delivers consistent chip load and surface finish in production and job-shop environments. It is installed by machinists and CNC programmers working in metalworking, toolroom, and precision manufacturing applications.

This cutter is suited for milling dovetail slots, V-grooves, and angular chamfers in steel, stainless steel, cast iron, and high-temperature alloys. The 1/2-inch shank fits standard ER collet chucks and end mill holders. The 5/16-inch neck diameter and 1-39/64-inch neck length provide clearance for deeper slot applications without sacrificing rigidity. It is appropriate for both CNC machining centers and manual knee mills where precise angular geometry is required.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard material cutting
• AlTiN coating improves heat resistance and tool life in ferrous and high-temperature alloy applications
• 60-degree included angle for standard dovetail and chamfer geometry
• 6-flute design distributes cutting load and supports consistent surface finish
• 5/16-inch neck diameter with 1-39/64-inch neck length provides clearance for deeper slot entry
• 1/2-inch shank diameter compatible with standard collet chucks and end mill holders

Compatibility

Designed for use with standard 1/2-inch ER collet chucks and end mill holders on CNC machining centers and manual milling machines requiring a 60-degree double angle cutter profile.

Installation Notes

This cutter is installed by qualified machinists. Secure the 1/2-inch shank in a properly sized collet chuck or end mill holder and verify runout before cutting. Always power down and lock out the spindle before changing tooling. Follow machine manufacturer torque specifications for collet nut tightening and confirm workpiece fixturing is rigid before engaging the cutter.
