Harvey Tool 934831-C3 Square End Mill 0.031 in 3 Flute Carbide

Product Description

The HARVEY TOOL 934831-C3 is a solid carbide square end mill designed for high-precision milling in demanding machining environments. With a 0.0310-inch cutting diameter and a 0.046-inch length of cut, this tool is built for micro-milling applications where dimensional accuracy is critical. The 3-flute geometry with a 30-degree helix angle promotes efficient chip evacuation while maintaining surface finish quality. An AlTiN coating provides thermal resistance and extends tool life in ferrous and high-temperature alloy materials. This end mill is installed and operated by machinists and CNC programmers working with vertical machining centers, CNC mills, and similar equipment.

This end mill is suited for small-feature milling in precision components across industries such as aerospace, medical device manufacturing, and mold and die work. The extended reach design, with a reach length of 0.218 inches, allows access to recessed features and tight pockets. The 0.125-inch shank diameter fits standard 1/8-inch collets and tool holders commonly found in CNC machining setups handling micro and miniature work.

Key Features

• 0.0310-inch (1/32 inch) cutting diameter for micro-milling precision work
• AlTiN coating for thermal resistance and extended tool life in hard materials
• 3-flute design with 30-degree helix angle for efficient chip evacuation
• Extended reach with 0.218-inch reach length for accessing recessed features
• Right-hand cut, right-hand flute configuration — standard CNC spindle compatible
• Centercutting geometry allows plunge entry

Compatibility

Designed for use in CNC milling machines and machining centers with 1/8-inch collets or tool holders; compatible with applications requiring a length-of-cut range up to 0.1000 inches and a 0.125-inch shank diameter.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is locked out before changing tooling. Use a properly sized collet or tool holder matched to the 0.125-inch shank diameter and torque to the tool holder manufacturer's specification. At micro diameters, runout control is critical — inspect collet and holder condition before each use to avoid premature tool breakage.
