Harvey Tool 945547 Square End Mill 3/64 in 3 Flute Carbide

Product Description

The HARVEY TOOL 945547 is a solid carbide square end mill designed for precision milling in metalworking, moldmaking, and general machining applications. With a 3/64 inch (0.047 inch) cutting diameter and a 0.07 inch length of cut, this tool is built for tight-tolerance work in confined areas and small-feature geometries. The three-flute configuration balances chip evacuation with cutting stability, and the 30-degree helix angle promotes smooth cutting action. The bright/uncoated finish keeps the tool ready for a wide range of workpiece materials without coating-related thermal concerns. Overall length is 2.5 inches with a 1/8 inch shank diameter.

This end mill suits small-part machining operations where fine detail and dimensional accuracy are critical. The extended reach design and 3/16 inch reach length make it appropriate for milling recessed features, pockets, and slots that standard-reach tooling cannot access. It is a single-end, right-hand cut tool intended for use in CNC machining centers and manual mills with collet or end mill holders accepting a 1/8 inch shank. Machinists working in aerospace, medical device, and precision die-mold environments will find it well suited to their requirements.

Key Features

• 3/64 inch (0.047 inch) cutting diameter for fine, small-feature milling
• Solid carbide construction for rigidity and wear resistance
• Three flutes with 30-degree right-hand helix for balanced cutting and chip flow
• Extended reach design with 3/16 inch reach length for accessing recessed features
• Centercutting capability allows plunge entry into the workpiece
• Bright/uncoated finish compatible with a broad range of workpiece materials

Compatibility

Designed for use in CNC machining centers and manual mills equipped with collet systems or end mill holders accepting a 1/8 inch shank diameter. Suitable for milling ferrous and non-ferrous metals, plastics, and composites in applications requiring small-diameter precision cutting.

Installation Notes

This tool is installed by a machinist or CNC setup technician into a compatible collet or end mill holder rated for 1/8 inch shank tooling. Ensure the machine spindle is fully stopped and locked out before changing tooling. Verify runout at the cutting end with a dial indicator before commencing a cut, as excessive runout at this diameter will accelerate tool wear and compromise surface finish. Follow the tool manufacturer and machine builder guidelines for feeds, speeds, and depth of cut for the specific workpiece material.
