Harvey Tool 802431 Square End Mill 1/32 in 4 Flute Carbide

Product Description

The HARVEY TOOL 802431 is a 4-flute, solid carbide square end mill designed for precise milling in tight-tolerance applications. With a mill diameter of 1/32 inch (0.031 inches), a length of cut of 3/32 inch (0.093 inches), and an overall length of 1-1/2 inches, this miniature end mill is built for small-feature machining where rigidity and accuracy are critical. A 30-degree helix angle improves chip evacuation and reduces cutting forces. The bright/uncoated finish suits a range of workpiece materials. Machinists and toolmakers working on CNC mills install this tool for fine detail work, micro slots, and contour passes requiring a small-diameter cutting profile.

This end mill fits applications demanding fine detail in small cavities, slots, and contours. The 1/8-inch shank diameter (0.125 inches) works with standard collets and end mill holders on CNC machining centers and manual mills. The extended-reach design, with a reach length of 3/16 inch (0.187 inches), gives clearance for deeper pockets without sacrificing stability. Single-end configuration means the tool is replaced rather than reversed when the cutting edge wears. Suitable for light finishing and semi-finishing passes in ferrous and non-ferrous metals, plastics, and composites.

Key Features

• 1/32 inch (0.031 inches) mill diameter for small-feature and micro-slot work
• 4-flute geometry for improved finish quality and feed rate capability
• 30-degree helix angle promotes efficient chip evacuation
• Solid carbide construction for rigidity and wear resistance at small diameters
• Centercutting design allows plunge entry into workpiece
• Extended reach with 3/16 inch reach length for deeper pocket access
• Bright/uncoated finish compatible with a broad range of materials

Compatibility

Designed as a direct-fit replacement for standard 1/8-inch shank collets and end mill holders on CNC machining centers and manual milling machines requiring a 1/32-inch diameter square end mill.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Secure the shank firmly in a clean, properly sized collet or end mill holder to the tool holder manufacturer's specified clamping procedure. Verify runout with a dial indicator before beginning the cut, as runout is especially consequential at small diameters.
