Accupro 31553712 Double Angle Milling Cutter 60 Degree 1/2 in

Product Description

The ACCUPRO 31553712 is a double angle milling cutter designed for precision chamfering, dovetail slot preparation, and angular groove cutting in metalworking applications. Built from solid carbide with an AlTiN coating, it delivers extended tool life under the high heat and cutting pressures common in ferrous and hardened materials. The included angle is 60 degrees. The cutter measures 1/2 inch in cut diameter with a 7/64 inch (0.109 inch) cutting width, and it seats on a 1/2 inch shank for secure chuck engagement. Six cutting teeth provide a balance of material removal rate and surface finish quality. Total overall length is 3 inches. Machinists and toolroom operators install this cutter on CNC machining centers and manual mills.

This cutter is suited for production and job-shop environments where consistent angular profiles are required. Typical applications include chamfering part edges, cutting dovetail features, and preparing mating surfaces in aluminum, steel, stainless, and cast iron. The 5/16 inch neck diameter and 1-7/64 inch neck length allow reach into recessed features without shank interference. The AlTiN coating makes it particularly effective in dry or semi-dry machining conditions where coolant use is limited. It is sold individually and sized for standard 1/2 inch collet or end mill holder systems commonly found in VMC and HMC setups.

Key Features

• 60-degree included angle for standard chamfer and dovetail geometries
• Solid carbide construction for rigidity and wear resistance in hard materials
• AlTiN coating extends tool life in high-temperature cutting conditions
• Six teeth for improved finish and efficient material removal
• 5/16 inch neck diameter allows reach into confined or recessed features
• 1/2 inch shank compatible with standard collets and end mill holders

Compatibility

Designed as an OEM-style replacement and production double angle milling cutter for use in standard 1/2 inch collet chucks and end mill holders on CNC and manual milling machines.

Installation Notes

Installation is performed by a machinist or toolroom technician. Ensure the machine spindle is fully stopped and the tool changer or spindle lock is engaged before mounting or removing the cutter. Seat the shank fully in a clean, undamaged collet or end mill holder and torque the retention device to the holder specification. Inspect the cutting edges for chips before use, as carbide tooling is brittle and should not be used if edge damage is visible.
