Harvey Tool 801762-C3 Square End Mill 1/16 in 4 Flute Carbide

Product Description

The HARVEY TOOL 801762-C3 is a solid carbide square end mill designed for precision milling in demanding metalworking and machining applications. With a 1/16 inch (0.0625 inch) mill diameter and a 4-flute geometry, this end mill delivers clean, accurate cuts in tight tolerances. The AlTiN coating provides thermal resistance and extended tool life in high-speed cutting conditions. A 30-degree helix angle promotes efficient chip evacuation, and the centercutting design enables plunge-entry cuts without a pre-drilled pilot hole. This tool is sized for fine-feature work and is installed and operated by machinists and CNC mill technicians.

This end mill is suited for milling small features, slots, pockets, and contours in ferrous and non-ferrous metals, hardened steels, and similar materials. The 1/8 inch shank diameter fits standard collets and tool holders on CNC machining centers and manual knee mills. The 3/32 inch length of cut and 3/4 inch reach length make it appropriate for shallow-to-moderate depth passes in confined part geometries. Single-end configuration means the tool is replaced when worn rather than indexed.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard materials
• AlTiN coating for high-temperature performance and extended tool life
• 4-flute design balances chip load and surface finish quality
• 30-degree helix angle promotes chip evacuation and reduces cutting forces
• Centercutting geometry allows direct plunge entry without pilot drilling
• Right-hand cut, right-hand flute configuration for standard spindle direction

Compatibility

Designed for use in CNC machining centers and manual milling machines equipped with 1/8 inch collets or tool holders accepting a 0.1250 inch shank diameter.

Installation Notes

Installation should be performed by a qualified machinist or CNC technician with the machine powered down and the spindle fully stopped before tool changes. Ensure the shank is fully seated and properly torqued in the collet or end mill holder per the toolholder manufacturer specifications. Verify runout with a dial indicator after installation to confirm concentricity before cutting. Follow shop-standard feeds, speeds, and depth-of-cut guidelines appropriate for a 1/16 inch diameter solid carbide tool to avoid deflection or breakage.
