Harvey Tool 942220 Square End Mill 0.5mm 3 Flute Carbide

Product Description

The HARVEY TOOL 942220 is a solid carbide square end mill designed for precision milling in tight-tolerance applications. With a 0.5 mm (0.0200 inch) cutting diameter and a 0.06 inch length of cut, this tool is built for micro-milling work where dimensional accuracy is critical. The three-flute geometry with a variable helix angle improves chip evacuation and reduces chatter, making it well suited for finishing passes and fine detail work in hardened or difficult-to-machine materials. The bright, uncoated finish allows direct inspection of the cutting edge and is compatible with a wide range of workpiece materials. Machinists and tool-and-die professionals are the primary installers of this end mill.

This end mill is used in CNC vertical machining centers and high-speed spindle applications requiring sub-millimeter cutting diameters. The 1/8 inch shank diameter fits standard collets and tool holders commonly found in precision machining shops. It is particularly suited for mold-making, medical device components, electronics housings, and other fine-feature work where a larger tool cannot reach. The 1.5 inch overall length provides adequate clearance for most shallow-pocket operations within its intended length-of-cut range.

Key Features

• 0.5 mm (0.0200 inch) cutting diameter for micro-scale milling operations
• Solid carbide construction for rigidity and wear resistance at elevated feed rates
• Three-flute design with variable helix angle reduces harmonics and improves surface finish
• Center-cutting capable, allowing direct plunge entry into the workpiece
• Right-hand cut and right-hand flute orientation for standard CNC spindle compatibility
• Bright, uncoated finish suitable for a broad range of workpiece materials

Compatibility

Designed for use in CNC machining centers equipped with 1/8 inch collets or tool holders accepting a 0.125 inch shank diameter. Suitable for applications requiring a length-of-cut range up to 0.1000 inch.

Installation Notes

Installation and operation should be performed by qualified machinists familiar with CNC tooling and high-speed cutting parameters. Ensure the spindle is fully stopped and the machine is in a safe state before loading or unloading the tool. Use a properly sized collet or end mill holder rated for the 0.125 inch shank to prevent runout. At sub-millimeter diameters, tool deflection and runout tolerances are critical — verify holder condition and taper cleanliness before each use.
