Harvey Tool 990793-C6 3/32 in Solid Carbide Square End Mill

Product Description

The HARVEY TOOL 990793-C6 is a solid carbide square end mill designed for precision milling in demanding metalworking and machining applications. With a 3/32 inch (0.093 inch) cutting diameter and a 1/2 inch length of cut, this single-end mill delivers tight tolerances in confined pockets and slots. The three-flute geometry combined with a 34-degree variable helix angle reduces chatter and improves chip evacuation during high-speed passes. An AlTiN (aluminum titanium nitride) coating provides elevated heat resistance and extended tool life in ferrous and hardened materials. Licensed machinists and CNC operators working in job shops, tool rooms, and production environments are the primary users of this end mill.

This end mill suits precision milling operations in ferrous metals, stainless steel, titanium, and hardened steels where heat generation and tool deflection are primary concerns. The compact 3/32 inch diameter makes it well suited for fine detail work, small-radius inside corners, and narrow slot milling. The 1/8 inch shank diameter is compatible with standard collet systems commonly found on CNC machining centers and manual mills. The 2-1/2 inch overall length provides enough clearance for most standard setups without excessive reach-related deflection.

Key Features

• 3/32 inch (0.093 inch) cutting diameter for fine detail and small-feature milling
• 3-flute variable helix geometry at 34 degrees reduces vibration and improves surface finish
• AlTiN coating provides heat and wear resistance in ferrous and hardened materials
• Solid carbide construction delivers rigidity and dimensional stability under load
• Center-cutting design allows plunge entry as well as conventional side milling
• Right-hand cut and right-hand flute direction for standard CNC and manual mill spindles

Compatibility

Designed for use with standard 1/8 inch collet or tool holder systems on CNC machining centers and manual mills. No specific OEM system compatibility is stated for this part.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator familiar with end mill setup procedures. Ensure the machine spindle is fully stopped and powered down before changing tooling. Seat the 1/8 inch shank fully and evenly in a matching collet or end mill holder and torque to the tool holder manufacturer's specification. Verify runout with a dial indicator before beginning a cut, as runout on small-diameter carbide tools can cause premature breakage.
