Harvey Tool 33231 Square End Mill 1/32 in 3 Flute Carbide

Product Description

The HARVEY TOOL 33231 is a solid carbide square end mill designed for high-precision milling in tight geometries and deep-reach applications. Built from micrograin carbide, this tool delivers the rigidity and edge retention needed when cutting in demanding materials at small diameters. The 1/32 inch (0.0310 inch) cutting diameter pairs with a 3/64 inch (0.0470 inch) length of cut and a 30-degree helix angle to produce clean, accurate results in slots, pockets, and profiling operations. Three flutes provide a balance of chip evacuation and cutting edge strength at this scale. The 1/8 inch shank diameter and 2-1/2 inch overall length make it compatible with standard collet systems used in CNC machining centers and manual mills.

This end mill is suited for precision machining applications where small-diameter tooling is required, such as micro-mold work, detailed profiling, and fine slotting in metals, plastics, and composites. The extended reach configuration, with a 5/32 inch reach length, allows access to features that standard-length tools cannot reach. Right-hand cut and right-hand flute geometry follow conventional milling conventions. The centercutting design enables plunge entry directly into the workpiece without a pre-drilled pilot hole. This tool is typically run by machinists and CNC programmers on vertical machining centers, routers, or precision milling machines.

Key Features

• Micrograin solid carbide construction for edge retention and rigidity at small diameters
• 3 flutes with spiral, right-hand cut and right-hand flute geometry
• 30-degree helix angle for smooth chip flow and reduced cutting forces
• Centercutting design allows direct plunge entry
• Extended reach with 5/32 inch reach length for deep-feature access
• Uncoated finish suitable for broad material compatibility

Compatibility

Designed as an OEM-style replacement-grade solid carbide square end mill for use in CNC machining centers and manual milling machines accepting a 1/8 inch shank diameter via standard collet or end mill holder.

Installation Notes

Installation is performed by machinists using a collet chuck or end mill holder rated for the 1/8 inch shank diameter. Ensure the machine spindle is fully stopped and locked before seating or removing the tool. At this small diameter, feed rates and spindle speeds must be carefully calculated to avoid tool deflection or breakage. Follow machine tool manufacturer guidelines and applicable shop safety procedures when setting tool offsets and running initial cuts.
