Harvey Tool 58331 Square End Mill 1/32 in 3 Flute Carbide

Product Description

The HARVEY TOOL 58331 is a solid carbide square end mill designed for precision milling in tight-tolerance machining applications. Built with three flutes and a 30-degree helix angle, it delivers clean chip evacuation and smooth cutting action in a variety of workpiece materials. The 1/32 inch (0.031 inch) cutting diameter and 0.046 inch length of cut make this tool well-suited for fine detail work, slotting, and profiling in small-feature components. The extended reach design, with a 5/8 inch reach length and 2.5 inch overall length, allows access to deeper features without sacrificing rigidity. The bright, uncoated finish keeps tool prep simple and maintains sharp edge geometry out of the box.

This end mill is used in CNC machining centers and manual mills across tool-and-die, mold, medical device, aerospace, and electronics manufacturing environments. It is a single-end, right-hand cutting tool with right-hand flute direction, making it compatible with standard spindle configurations. The centercutting capability allows direct plunge entry into the workpiece. Its 1/8 inch shank diameter fits standard collet chucks and tool holders commonly found in precision machining setups handling small-diameter tooling.

Key Features

• Solid carbide construction for rigidity and wear resistance at small diameters
• Three-flute geometry balances chip room with core strength at 1/32 inch diameter
• 30-degree helix angle promotes smooth cutting and efficient chip evacuation
• Extended reach with 5/8 inch reach length for access to deeper features
• Centercutting design enables direct plunge milling
• Bright, uncoated finish suitable for a wide range of workpiece materials

Compatibility

Designed as a standard small-diameter square end mill for use in CNC machining centers and manual mills equipped with 1/8 inch collet chucks or compatible tool holders accepting right-hand, single-end carbide tooling.

Installation Notes

Installation should be performed by a qualified machinist following the tool holder manufacturer's torque and runout specifications. Ensure the spindle is fully stopped and the machine is in a safe state before mounting or removing the tool. Verify collet and chuck condition before use, as runout at this diameter can significantly affect tool life and cut quality. Follow all applicable shop safety procedures when handling small-diameter carbide tooling, as edges are sharp and carbide is brittle.
