Harvey Tool 14040-C3 Square End Mill 0.04 in 4 Flute Carbide

Product Description

The HARVEY TOOL 14040-C3 is a miniature square end mill designed for high-precision milling in tight tolerances and small-feature applications. Built from solid carbide and finished with an AlTiN coating, it delivers hardness and heat resistance suited to demanding cutting conditions. The tool measures 0.04 inches in cutting diameter with a 1/16-inch length of cut (LOC) and runs four flutes at a 30-degree helix angle. Centercutting geometry allows plunge entry directly into the workpiece. Machinists and toolmakers working in die, mold, and micro-component applications are the primary users.

This end mill is suited for finishing passes and small-feature profiling in non-ferrous metals, hardened steels, and composites where a miniature cutting diameter is required. The 1/8-inch shank diameter fits standard collets and toolholding systems found on CNC machining centers and high-speed spindles. The 1-1/2-inch overall length provides adequate reach while maintaining rigidity at this diameter. Right-hand cut and right-hand flute configuration is standard.

Key Features

• Solid carbide construction for rigidity and wear resistance in precision milling
• AlTiN coating provides elevated heat resistance and extended tool life in hard materials
• 4-flute geometry improves surface finish and material removal rate at small diameters
• 30-degree helix angle balances cutting forces for smooth chip evacuation
• Centercutting design enables direct plunge milling without a pre-drilled entry point
• Right-hand cut and right-hand flute for compatibility with standard CNC spindle rotation

Compatibility

Designed for use with 1/8-inch collet toolholding systems on CNC machining centers and high-speed spindles requiring a miniature square end mill profile.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is in a safe state before changing tooling. Seat the 1/8-inch shank fully and evenly in the collet before tightening to the collet nut torque specification for that toolholder system. At this cutting diameter, runout control is critical — use a quality collet and verify runout before production cutting.
