Harvey Tool 14039-C3 Square End Mill 1mm 4 Flute Altin Carbide

Product Description

The HARVEY TOOL 14039-C3 is a single-end square end mill designed for precision milling in tight-tolerance applications. Built from solid carbide with an AlTiN coating, it runs at 1 mm (0.0390 inch) cutting diameter with a 0.058-inch length of cut and a 1/8-inch shank diameter. The 4-flute geometry and 30-degree helix angle promote smooth chip evacuation and consistent surface finish. Overall length is 1.5 inches. The centercutting design allows plunge entry, adding versatility in die work, mold machining, and general contouring. Machinists and tool-and-die professionals working on small-feature components are the primary users of this tool.

This end mill is suited for small-feature milling operations on hardened steels, stainless alloys, cast iron, and other difficult-to-machine materials where AlTiN coating provides thermal resistance and extended tool life. Its compact 1 mm diameter makes it appropriate for slotting, profiling, and contouring narrow channels or fine detail geometry in mold cavities, medical components, and precision mechanical parts. The 1/8-inch shank fits standard collet chucks used on CNC machining centers and high-speed spindles.

Key Features

• 1 mm cutting diameter with 0.058-inch length of cut for fine-feature work
• Solid carbide construction for rigidity and wear resistance in hardened materials
• AlTiN coating provides high-temperature resistance and reduced built-up edge
• 4 flutes with 30-degree right-hand helix for efficient chip flow and surface finish
• Centercutting design allows direct plunge entry
• Single-end configuration with 1/8-inch shank diameter for common collet compatibility

Compatibility

Designed for use with standard 1/8-inch collet chucks on CNC machining centers and high-speed milling spindles. No specific compatible machine models or replaced part numbers were identified in the available product data.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully stopped and the machine is in a safe state before tool changes. Seat the shank fully into the collet and torque the collet nut to the spindle manufacturer's specification. At 1 mm diameter, tool runout is critical — verify TIR with a dial indicator before production runs to prevent premature tool breakage.
