Harvey Tool 951315-C3 Square End Mill 1/64 in 3 Flute Altin

Product Description

The HARVEY TOOL 951315-C3 is a solid carbide square end mill designed for precision milling in demanding applications. With a 1/64 inch (0.0156 inch) cutting diameter and a 5/32 inch (0.156 inch) length of cut, this end mill is built for fine detail work and tight-tolerance machining in hardened metals, stainless steels, and other difficult-to-machine materials. The AlTiN coating provides high heat resistance and extended tool life under aggressive cutting conditions. Three flutes deliver a balance of chip evacuation and surface finish quality in a tool this small. At 2.5 inches overall length with a 1/8 inch shank diameter, it fits standard collet toolholding systems used on CNC machining centers and manual mills.

This end mill is suited for small-feature milling, engraving, slotting, and profiling operations where a very small cutting diameter is required. The 30-degree helix angle promotes smooth cutting action and reduces deflection on fine features. It is single-end geometry, center-cutting capable, and runs right-hand cutting with right-hand flute direction. Typical users include tool-and-die shops, mold makers, medical device manufacturers, and aerospace machinists working with tight geometries and hard alloys.

Key Features

• 1/64 inch (0.0156 inch) cutting diameter for fine-detail and small-feature machining
• Solid carbide construction for rigidity and wear resistance in hard materials
• AlTiN coating for high-temperature resistance and extended tool life
• 3-flute design balances chip clearance and finish quality at small diameters
• 30-degree helix angle reduces cutting forces and deflection
• Center-cutting geometry allows plunge entry

Compatibility

Designed for use in CNC machining centers and manual mills equipped with 1/8 inch collet or toolholder systems accepting a 0.125 inch shank diameter.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and the tool changer or collet is properly locked before handling. Seat the shank to the recommended grip depth in the collet or toolholder to minimize runout and prevent tool pullout. At this diameter, proper speeds, feeds, and minimal runout are critical to avoid tool breakage.
