Harvey Tool 72016-C3 Square End Mill 0.4mm 2 Flute Altin

Product Description

The HARVEY TOOL 72016-C3 is a solid carbide square end mill designed for precision milling in demanding cutting applications. With a 0.4 mm (0.0160 inch) cutting diameter and a 2-flute geometry, this end mill is built for tight-tolerance work in hard materials where accuracy and surface finish are critical. The AlTiN coating improves wear resistance and thermal stability, extending tool life during dry or high-speed cutting. The 30-degree helix angle promotes smooth chip evacuation and reduces cutting forces. This tool is a single-end design intended for use by machinists and tooling professionals working with CNC milling equipment.

This end mill is suited for high-precision machining operations including slotting, profiling, and contouring in ferrous and non-ferrous materials. The 0.048-inch length of cut (LOC) makes it appropriate for shallow-depth passes in miniature or micro-scale features. The 1/8-inch shank diameter allows direct mounting in standard collets on CNC machining centers and manual mills. Applications include mold and die work, medical component machining, and precision aerospace part production where small-diameter tooling is required.

Key Features

• 0.4 mm (0.0160 inch) cutting diameter for micro and miniature milling applications
• AlTiN coating for enhanced heat resistance and extended tool life in hard materials
• 2-flute design promotes chip clearance in confined cutting geometries
• 30-degree right-hand helix angle for smooth cutting action and reduced vibration
• Centercutting capable, allowing plunge entry into workpieces
• Solid carbide construction provides rigidity and dimensional stability

Compatibility

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

Installation Notes

Installation should be performed by a qualified machinist familiar with small-diameter carbide tooling. Ensure the collet and toolholder are clean and free of debris before seating the shank to the full recommended engagement depth. Carbide end mills are brittle — avoid side-loading beyond rated parameters and do not use an adjustable wrench or improvised tooling to seat or remove the cutter. Verify spindle runout is within acceptable limits before machining, as excessive runout significantly reduces tool life and accuracy at this diameter.
