Harvey Tool 73060 Square End Mill 1/16 in 4 Flute Carbide

Product Description

The HARVEY TOOL 73060 is a square end mill designed for precision milling in tight geometries and fine-detail applications. Built from micrograin solid carbide, it delivers the rigidity and edge retention required when working at small diameters. The cutter measures 0.062 inches in diameter with a 0.18-inch length of cut, a 0.125-inch shank diameter, and a 1.5-inch overall length. Four spiral flutes at a 30-degree helix angle promote efficient chip evacuation while maintaining a clean finish. The centercutting geometry allows plunge entry, giving machinists flexibility in their toolpath strategy. Licensed machinists and CNC operators in production and prototype shops are the primary users of this tool.

This end mill is suited for slotting, profiling, and pocketing operations where fine feature resolution is required. Its small 1/16-inch diameter makes it appropriate for micro-machining applications in mold and die, medical device, and aerospace component work. The uncoated micrograin carbide construction performs well in non-ferrous metals, plastics, and graphite. Right-hand cut and right-hand flute orientation are standard for use with conventional CNC machining center spindles.

Key Features

• Micrograin solid carbide construction for edge retention at small diameters
• Four spiral flutes with 30-degree helix angle for efficient chip evacuation
• Centercutting design allows direct plunge entry
• Right-hand cut and right-hand flute orientation for standard CNC spindle use
• Uncoated finish suited for non-ferrous metals, plastics, and graphite
• 0.125-inch shank diameter fits standard collets and toolholders

Compatibility

Designed for use in CNC machining centers and manual mills equipped with standard ER or precision collet toolholding systems accepting a 0.125-inch shank diameter.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully powered down and at rest before loading or removing the tool from the collet. Use a calibrated torque wrench and appropriate collet nut wrench to secure the toolholder to the manufacturer-specified setting. Inspect the cutting edges under magnification before use, as micrograin carbide tools at this diameter are sensitive to chipping from improper handling or incorrect runout.
