Harvey Tool 73008 Square End Mill 0.008 in 4 Flute Carbide

Product Description

The HARVEY TOOL 73008 is a solid carbide square end mill designed for precision milling in tight-tolerance machining applications. With a cutting diameter of 0.0080 inches (0.2 mm) and a length of cut of 0.024 inches, this tool is built for micro-scale work where dimensional accuracy is critical. The 4-flute geometry and 30-degree helix angle promote smooth chip evacuation and stable cutting action at small diameters. The 0.125-inch shank fits standard 1/8-inch collets and tool holders. This end mill is installed and operated by machinists, CNC programmers, and tooling technicians working in precision manufacturing environments.

This end mill is suited for micro-milling operations in materials that demand sharp, rigid tooling. The bright uncoated finish and solid carbide construction make it appropriate for non-ferrous metals, plastics, composites, and similar materials where a coated tool is not required. The 1.5-inch overall length provides adequate clearance for most standard setups. Its centercutting capability allows direct plunge entry without a pre-drilled pilot hole, adding flexibility in programming and fixturing strategies.

Key Features

• 0.0080-inch (0.2 mm) cutting diameter for micro-milling precision work
• 4-flute design with 30-degree helix angle for improved chip flow and surface finish
• Solid carbide construction for rigidity and wear resistance at small diameters
• Centercutting geometry allows direct plunge entry
• Right-hand cut and right-hand flute direction for standard CNC spindle operation
• Bright uncoated finish suitable for non-ferrous and non-abrasive material applications

Compatibility

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

Installation Notes

This tool should be installed by a qualified machinist or CNC technician. Ensure the spindle is fully powered down and locked before changing tooling. Use a properly sized collet or tool holder matched to the 0.125-inch shank to prevent runout, which is especially critical at this diameter. Avoid over-tightening the collet nut, as distortion at small shank sizes can increase runout and reduce tool life.
