Accupro 31589781 Double Angle Milling Cutter 60 Deg 1/8 in

Product Description

The ACCUPRO 31589781 is a double angle milling cutter designed for precise grooving, chamfering, and dovetail-style milling operations on metalworking machines. Built from solid carbide and finished with an AlTiN (aluminum titanium nitride) coating, it handles hardened steels and high-temperature alloys at elevated cutting speeds. The 60-degree included angle, 1/8 inch cut diameter, and 0.036 inch cut width make it suited for fine detail work in tight geometries. Four teeth provide a balance of chip clearance and surface finish. Overall length is 2 inches with a 1/8 inch straight shank for direct collet or end-mill holder mounting.

This cutter fits standard CNC machining centers, manual knee mills, and multi-axis machines where small-diameter angle milling is required. Typical applications include engraving lead-ins, V-groove milling, deburring chamfers, and precision slot work on ferrous and non-ferrous workpieces. The 1/16 inch neck diameter and 0.536 inch neck length allow access to recessed features without interference from the shank. Machinists, tool-and-die makers, and CNC programmers working in job shops or production environments are the primary users.

Key Features

• 60-degree included angle for chamfering and V-groove milling
• Solid carbide construction for rigidity and wear resistance in ferrous materials
• AlTiN coating improves heat resistance and extends tool life in dry or high-speed cutting
• Four-flute geometry balances chip evacuation with finish quality
• 1/16 inch neck diameter with 0.536 inch neck length for access to recessed features
• 1/8 inch straight shank compatible with standard ER collets and end-mill holders

Compatibility

Designed as a direct-mount replacement or production cutter for CNC machining centers and manual mills equipped with 1/8 inch collets or end-mill holders accepting straight-shank tooling.

Installation Notes

Installation is performed by a machinist or CNC setup technician. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Seat the 1/8 inch shank fully into a clean, undamaged collet or end-mill holder and torque the retention nut to the tool-holder specification. Inspect the cutting edges for chips before use, as solid carbide is brittle and sensitive to improper handling or side-loading during setup.
