Harvey Tool 946903-C3 Double Angle Milling Cutter 90 Deg

Product Description

The HARVEY TOOL 946903-C3 is a solid carbide double angle milling cutter designed for precision groove milling, chamfering, and dovetail-adjacent profiling operations on CNC machining centers and manual mills. It features a 90-degree included angle, a 1/4-inch cutting diameter, and a 1/8-inch cutting width. The 1/4-inch shank connects directly to standard collets or end mill holders. An AlTiN coating improves heat resistance and tool life in ferrous and hardened materials. Four cutting teeth deliver a balance of chip clearance and surface finish. Overall length is 2 inches, keeping the tool compact and rigid in the spindle.

This cutter suits tool and die shops, mold makers, and precision machining operations requiring accurate angled grooves or chamfer profiles. It is appropriate for use on steel, stainless, cast iron, and similar materials where AlTiN coating performance is advantageous. The compact geometry and 1/8-inch neck diameter make it well suited for reaching into confined features without excessive overhang.

Key Features

• 90-degree included angle for chamfering and symmetric groove milling
• Solid carbide construction for rigidity and wear resistance
• AlTiN coating for elevated heat resistance and extended tool life in ferrous materials
• 4-flute design balances chip evacuation with finish quality
• 1/4-inch shank compatible with standard ER collets and end mill holders
• Compact 2-inch overall length reduces overhang and vibration tendency

Compatibility

Designed as an OEM-style solid carbide double angle milling cutter fitting standard 1/4-inch collet and end mill holder systems used on CNC and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer's spindle and toolholder specifications. Ensure the machine spindle is fully stopped and locked out before inserting or removing the cutter. Seat the 1/4-inch shank to the full recommended engagement depth in the collet or holder and torque the collet nut per the toolholder manufacturer's specification. Inspect cutting edges for chipping before each use and do not run the cutter beyond its rated diameter at excessive feed rates.
