Harvey Tool 923031 Square End Mill 1/32 in 3 Flute Carbide

Product Description

The HARVEY TOOL 923031 is a solid carbide square end mill designed for high-precision milling in demanding machining environments. Built with a 3-flute, variable helix geometry, this end mill reduces chatter and improves chip evacuation during both roughing and finishing passes. The cutting diameter measures 1/32 inch (0.0310 inches decimal), with a 5/32 inch length of cut (0.156 inches decimal) and a 2-1/2 inch overall length. The 1/8 inch shank diameter suits standard collet holders commonly found in CNC machining centers and high-speed spindles. The bright, uncoated finish makes this tool well-suited for non-ferrous metals and materials where coating adhesion could affect surface finish.

This end mill is intended for precision slot milling, profiling, and finishing operations requiring a small-diameter cutting tool. It is centercutting, allowing plunge entry into workpieces. Right-hand cut and right-hand flute direction make it compatible with standard CNC spindle configurations. Typical applications include intricate detail work in aluminum, brass, plastics, and other machinable materials where dimensional accuracy at small feature sizes is critical. Machinists and tool-and-die professionals working in production or prototype environments will find this tool appropriate for tight-tolerance work.

Key Features

• 1/32 inch (0.0310 inches) cutting diameter for fine detail and tight-tolerance features
• 3-flute variable helix design reduces chatter and improves surface finish
• Centercutting geometry allows direct plunge entry without pre-drilling
• Solid carbide construction provides rigidity and wear resistance in precision applications
• Bright, uncoated finish suited for non-ferrous metals and plastics
• Right-hand cut and right-hand flute direction for use with standard CNC spindle setups

Compatibility

Designed for use with standard 1/8 inch collet holders and CNC machining centers equipped with high-speed spindles capable of running small-diameter solid carbide tooling.

Installation Notes

Installation of this end mill should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Seat the 1/8 inch shank fully in the collet to the recommended grip length to minimize runout and tool deflection. Given the small diameter of this tool, use appropriate feed and speed parameters to avoid breakage — consult the manufacturer cutting data for recommended starting parameters.
