Harvey Tool 58320 Square End Mill 0.5mm 3 Flute Carbide

Product Description

The HARVEY TOOL 58320 is a solid carbide square end mill designed for precision micro-milling applications. With a 0.5 mm (0.0200 inch) cutting diameter and a 1/32 inch (0.03 inch) length of cut, this tool is built for tight-tolerance work in small-feature machining. The three-flute geometry and 30-degree helix angle promote efficient chip evacuation while maintaining rigidity at small diameters. The bright/uncoated finish makes it well suited for non-ferrous metals, plastics, and composite materials. It ships as a single-end tool with extended reach, making it a reliable choice for machinists working in confined or deep-pocket geometries.

This end mill is used in CNC machining centers and high-speed milling applications where fine detail and small-diameter cutting are required. The 1/8 inch shank diameter fits standard collets found on most CNC machines and precision manual mills. Extended reach capability and a 0.4 inch reach length allow access to features that shorter tools cannot reach. Typical applications include mold and die work, prototype machining, medical component manufacturing, and electronics-related precision work where micro-scale features demand consistent tool performance.

Key Features

• 0.5 mm cutting diameter for micro-scale and fine-detail milling
• Three-flute design promotes chip clearance and surface finish quality
• 30-degree helix angle balances cutting efficiency with tool stability
• Solid carbide construction provides rigidity and wear resistance at small diameters
• Extended reach with 0.4 inch reach length for deep or confined feature access
• Bright/uncoated finish suitable for non-ferrous and non-metallic workpiece materials
• Center-cutting capable for plunge and ramp entry operations

Compatibility

Designed for use in CNC machining centers and precision milling machines equipped with 1/8 inch collets or compatible toolholding systems. Right-hand cutting and right-hand flute direction are standard for conventional CNC spindle configurations.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and the control is in a safe state before changing tooling. Seat the 1/8 inch shank fully and evenly in a clean, undamaged collet to prevent runout, which is especially critical at micro diameters. Inspect the cutting edges under magnification before use, as carbide tools at this diameter are brittle and sensitive to handling damage.
