Harvey Tool 968720 Square End Mill 0.5 Mm 3 Flute Carbide

Product Description

The HARVEY TOOL 968720 is a solid carbide square end mill engineered for precision micro-milling applications. With a cutting diameter of 0.5 mm (0.0200 inches) and a 1/32-inch length of cut, this tool is built for tight-tolerance work in small-feature machining. The three-flute geometry balances chip evacuation with cutting stability at reduced diameters. A variable helix angle minimizes chatter and improves surface finish at the cutting edge. The bright, uncoated finish makes it suitable for a range of workpiece materials without the added thermal load of a coated tool. Machinists and CNC programmers working on intricate components will find this end mill a reliable option for detailed slot and profile work.

This end mill is designed for use in CNC machining centers and high-speed milling applications where micro-diameter tooling is required. It is appropriate for industries such as medical device manufacturing, aerospace, electronics, and mold making, where fine features and tight dimensional tolerances are standard requirements. The 1/8-inch shank diameter allows it to seat in standard collets and tool holders sized for small-diameter end mills. Right-hand cutting and right-hand flute direction are the conventional configuration for most vertical and horizontal machining center setups.

Key Features

• 0.5 mm (0.0200 inch) cutting diameter for micro-scale milling operations
• Solid carbide construction provides rigidity and wear resistance at small diameters
• Three-flute design balances chip clearance with tool strength
• Variable helix geometry reduces harmonic chatter and improves finish quality
• Center-cutting capability allows direct plunge entry into workpiece material
• Bright, uncoated finish suits a broad range of compatible workpiece materials

Compatibility

Designed as a standard replacement or new-install micro end mill for CNC machining centers and milling machines fitted with 1/8-inch collets or compatible tool holders accepting a 0.125-inch shank diameter.

Installation Notes

Installation and tool changes must be performed by a qualified machinist or CNC technician with the spindle fully stopped and machine power isolated per shop safety procedures. Seat the 1/8-inch shank fully and evenly in a clean, undamaged collet before torquing the collet nut to the tool holder specification. Inspect the cutting edge under magnification before use, as micro-diameter carbide tools are susceptible to chipping during handling. Follow the tool manufacturer and machine builder guidelines for appropriate spindle speeds and feed rates for the specific workpiece material.
