Harvey Tool 973793-C6 Square End Mill 3/32 in 3 Flute Altin

Product Description

The HARVEY TOOL 973793-C6 is a solid carbide square end mill designed for precision milling operations across a range of ferrous and non-ferrous materials. With a 3/32-inch (0.0930-inch decimal) cutting diameter and a 9/64-inch (0.140-inch decimal) length of cut, this tool is built for tight-tolerance work in confined geometries. The 34-degree variable helix geometry reduces chatter and vibration during the cut. An AlTiN coating improves heat resistance and extends tool life in high-temperature cutting environments. This end mill is installed and operated by machinists, toolmakers, and CNC programmers working in job shop, aerospace, medical device, and general manufacturing settings.

This end mill is suited for slot milling, profiling, and finishing passes in applications where small-diameter tooling is required. The 1/8-inch shank fits standard collets and end mill holders used on CNC machining centers and manual mills. Its centercutting design allows plunge entry directly into the workpart. The 1-1/2-inch overall length keeps runout low while providing enough reach for typical small-feature work. Single-end configuration means the tool is replaced rather than reindexed at end of life.

Key Features

• AlTiN coating for elevated heat resistance and extended tool life in ferrous materials
• 34-degree variable helix reduces harmonic chatter and improves surface finish
• Centercutting geometry enables direct plunge milling without a pilot hole
• 3-flute design balances chip evacuation with cutting edge strength at small diameters
• Right-hand cut and right-hand flute direction for standard spindle operation
• Solid carbide construction delivers rigidity and wear resistance in demanding cuts

Compatibility

Designed for use with standard 1/8-inch collets and end mill holders on CNC machining centers and manual milling machines configured for small-diameter solid carbide tooling.

Installation Notes

Installation and tool changes must be performed with the machine spindle fully stopped and the control in a safe state. Secure the 1/8-inch shank in a clean, properly sized collet or end mill holder and tighten to the holder manufacturer's specification. Inspect the cutting edges and coating for damage before each use. Small-diameter carbide end mills are brittle and susceptible to breakage from side loading, improper feeds and speeds, or loose tool holding.
