Harvey Tool 76460-C3 Square End Mill 0.06in 4 Flute Carbide

Product Description

The HARVEY TOOL 76460-C3 is a solid carbide square end mill designed for precision milling in demanding machining environments. It features a 0.06-inch cutting diameter with 4 flutes and a 30-degree helix angle, providing efficient chip evacuation and a smooth cut finish. The AlTiN (aluminum titanium nitride) coating increases surface hardness and thermal resistance, extending tool life during high-speed cutting of ferrous metals, stainless, and hardened alloys. Centercutting geometry allows the tool to plunge directly into a workpiece. The 0.125-inch shank diameter and 1.5-inch overall length suit it for use in a wide range of CNC milling setups where small-diameter accuracy is critical.

This end mill is suited for micro-milling and fine detail work in CNC machining centers and manual mills running small-diameter cutting paths. Right-hand cut and right-hand flute direction are standard configuration for conventional and climb milling. Extended reach with a 0.5-inch reach length makes it capable of accessing features in deeper pockets or stepped part geometry. It is typically installed and operated by machinists and CNC programmers working in job shops, production machining, aerospace component work, and prototype fabrication where tight tolerances and small features are required.

Key Features

• 0.06-inch cutting diameter for micro-scale and fine-feature milling operations
• 4-flute geometry with 30-degree helix angle for efficient chip evacuation and surface finish
• AlTiN coating provides elevated thermal resistance and extended tool life in hard materials
• Centercutting design allows direct plunge entry into workpiece material
• Extended reach with 0.5-inch reach length for deeper pocket and stepped-feature access
• Solid carbide construction for rigidity and dimensional stability at high spindle speeds

Compatibility

Designed as an OEM-style replacement solid carbide square end mill compatible with standard CNC milling machine tool holders and collets accepting a 0.125-inch shank diameter.

Installation Notes

Installation is performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is powered off before changing tooling. Secure the shank in a clean, properly sized collet or end mill holder to the torque specification called out by your tooling system manufacturer. At this diameter, runout control is critical — inspect the collet and holder for wear before use, as excessive runout will accelerate breakage on small-diameter carbide tooling.
