Harvey Tool 73047-C3 Square End Mill 3/64 in 4 Flute Carbide

Product Description

The HARVEY TOOL 73047-C3 is a solid carbide square end mill designed for precision milling in tight-tolerance applications. With a 3/64 inch (0.0470 inch) cutting diameter and a 9/64 inch (0.1410 inch) length of cut, this tool is built for small-feature work where rigidity and edge integrity are critical. The 4-flute geometry with a 30-degree helix angle promotes efficient chip evacuation and smooth surface finishes. An AlTiN coating improves heat resistance and extends tool life in harder workpiece materials. The 1/8 inch shank diameter fits standard collets on CNC machining centers and manual mills. This end mill is used by machinists and toolmakers working in precision shops, prototype environments, and production floors.

This end mill is suited for milling small slots, pockets, and contours in ferrous and non-ferrous materials where fine detail and dimensional accuracy are required. The centercutting design allows plunge entry directly into the workpiece, expanding its range of use in complex multi-axis toolpaths. Right-hand cut and right-hand flute configuration is standard for conventional CNC spindle rotation. It is a single-end tool with a 1-1/2 inch overall length, which limits overhang and helps maintain stiffness at small diameters.

Key Features

• 3/64 inch cutting diameter for precision small-feature machining
• Solid carbide construction for rigidity and wear resistance
• AlTiN finish for elevated heat resistance in harder materials
• 4-flute design with 30-degree helix for efficient chip flow and surface finish
• Centercutting geometry allows direct plunge entry
• Right-hand cut and right-hand flute for standard CNC spindle compatibility

Compatibility

Designed as an OEM-style replacement and direct-fit option for 1/8 inch shank collets on CNC machining centers, CNC routers, and manual knee mills requiring a 3/64 inch square end mill.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Seat the shank fully into the collet to the recommended depth to minimize runout and prevent tool pullout under load. Do not exceed the tool manufacturer's recommended speeds and feeds for the workpiece material and coating type.
