Accupro 31689326 Double Angle Milling Cutter 90 Degree 1/8 in

Product Description

The ACCUPRO 31689326 is a double angle milling cutter designed for precision angular groove milling, chamfering, and dovetail operations on CNC and manual milling machines. Built from solid carbide, this cutter delivers rigidity and wear resistance suited to ferrous and non-ferrous workpiece materials. The 90-degree included angle, 1/8 inch cut diameter, and 0.062 inch cut width make it well-suited for tight, small-feature work where dimensional accuracy is critical. Four cutting teeth provide a balance of chip clearance and surface finish on short-run and production operations. Overall length is 1.5 inches with a 1/8 inch straight shank for direct collet mounting.

This cutter is intended for use in machining centers, CNC mills, and manual knee mills performing angular milling operations. It is suited to tool and die, mold making, aerospace component machining, and general precision metalworking where small-diameter angular features must be cut to tight tolerances. The uncoated solid carbide construction makes it a general-purpose choice across a range of materials, and its compact geometry allows access to narrow workpiece features. Machinists and tool room operators working with small intricate parts will find the 1/16 inch neck diameter useful for reaching recessed areas.

Key Features

• 90-degree included angle for standard chamfering and angular groove milling
• Solid carbide construction for superior hardness and wear resistance compared to high-speed steel
• 1/8 inch cut diameter and 0.062 inch cut width for small-feature precision work
• 1/16 inch neck diameter and 0.374 inch neck length allow access to narrow or recessed areas
• Four teeth for efficient chip evacuation and consistent finish on small angular cuts
• Uncoated finish suitable for use across a broad range of workpiece materials

Compatibility

Designed as a direct collet-mount cutter for use in any milling machine or machining center accepting a 1/8 inch straight shank via ER, 5C, or equivalent collet systems.

Installation Notes

Installation is performed by qualified machinists or tool room personnel. Secure the 1/8 inch shank in a properly sized collet or end mill holder and verify runout before cutting. Power down and lock out the spindle before installing or removing the cutter. Avoid excessive overhang beyond the collet to minimize deflection, and confirm spindle RPM and feed rate are appropriate for the workpiece material and cutter diameter before beginning the cut.
