Accupro 31670490 Double Angle Milling Cutter 90 Deg

Product Description

The ACCUPRO 31670490 is a solid carbide double angle milling cutter designed for precision milling of V-grooves, chamfers, and dovetail features on metalworking machining centers and manual mills. The cutter features a 90-degree included angle, a 3/8-inch cutting diameter, and a 1/8-inch cutting width. An AlTiN coating provides elevated heat resistance and extended tool life in ferrous and hardened materials. With 6 teeth and a 3/8-inch shank, this cutter suits CNC and manual milling applications requiring tight angular geometry. It is installed and operated by machinists and tool-and-die professionals in job shop and production environments.

This cutter is suited for milling operations that require accurate angular profiles in steel, stainless steel, cast iron, and similar ferrous alloys. The 1/4-inch neck diameter and 0.437-inch neck length provide clearance for profile milling in recessed or tight-access features. With a 2.5-inch overall length and 3/8-inch shank, it fits standard collet chucks and end mill holders common in vertical machining centers and manual knee mills. The solid carbide construction supports rigid, high-speed cutting conditions typical in production machining.

Key Features

• 90-degree included angle for V-groove and chamfer milling
• Solid carbide construction for rigidity and wear resistance
• AlTiN coating for improved heat resistance and tool life in ferrous materials
• 6-tooth design for balanced chip load and surface finish
• 1/4-inch neck diameter provides clearance for recessed feature access
• 3/8-inch shank compatible with standard collet chucks and end mill holders

Compatibility

Designed for use in standard collet chucks and end mill holders accepting a 3/8-inch shank diameter, compatible with vertical machining centers and manual milling machines used in general metalworking applications.

Installation Notes

Installation is performed by qualified machinists. Secure the shank fully in a collet chuck or end mill holder and torque the drawbar or collet nut according to the machine tool manufacturer specifications before operation. Verify spindle and tool holder runout before cutting to preserve edge geometry. Do not exceed the machine spindle speed rating for the selected cutter diameter.
