Harvey Tool 793320-C6 Square End Mill 0.5 Mm 4 Flute Carbide

Product Description

The HARVEY TOOL 793320-C6 is a solid carbide square end mill designed for precision micro-milling applications. With a 0.5 mm cutting diameter and a 0.12-inch length of cut, this tool is built for tight-tolerance work in hardened materials, composites, and non-ferrous metals. The AlTiN Nano coating increases surface hardness and heat resistance, extending tool life in demanding cutting conditions. Four right-hand flutes with a 35-degree helix angle provide efficient chip evacuation and smooth cutting action. This is a single-end, centercutting tool, meaning it can plunge as well as profile. Machinists and tool-and-die professionals working on CNC machining centers are the primary installers and operators of this tooling.

This end mill is suited for micro-milling operations where small feature sizes, fine surface finishes, and dimensional accuracy are critical. Typical applications include mold and die work, medical device components, aerospace precision parts, and electronics fixtures. The 4 mm shank diameter fits standard ER-series collet chucks commonly found on high-speed vertical machining centers and micro-milling spindles. The 40 mm overall length keeps the tool compact and rigid, reducing deflection at small diameters. Right-hand cutting direction is standard for conventional and climb milling on CNC equipment.

Key Features

• 0.5 mm cutting diameter for micro-scale feature milling
• AlTiN Nano coating for elevated heat resistance and extended tool life
• 4 right-hand flutes with 35-degree helix for efficient chip evacuation
• Centercutting design allows direct plunge entry
• Solid carbide construction for rigidity at small diameters
• 4 mm shank diameter compatible with standard ER collet toolholders

Compatibility

Designed for use in CNC machining centers equipped with high-speed spindles and ER-series collet chucks accepting a 4 mm shank. Suitable for right-hand spindle rotation. No specific machine model compatibility was provided in the product data.

Installation Notes

This tool should be installed by a qualified machinist using a properly sized ER collet and torqued to the collet nut manufacturer specification. Verify spindle runout before use, as excessive runout at this diameter will accelerate tool wear and cause dimensional error. At 0.5 mm diameter, feeds and speeds must be carefully calculated for the specific workpiece material to avoid tool breakage. Never use this tool on manual mills or equipment incapable of maintaining consistent spindle speed and feed rate control.
