Harvey Tool 973762-C6 Square End Mill 1/16 in 3 Flute

Product Description

The HARVEY TOOL 973762-C6 is a solid carbide square end mill designed for precision milling in demanding machining environments. With a 1/16 inch cutting diameter and a 3/32 inch length of cut, this tool is built for tight-tolerance work in small-feature applications. It runs three flutes with a variable helix geometry, which reduces harmonic chatter and improves chip evacuation during high-speed cuts. An AlTiN coating adds thermal resistance and extends tool life when cutting hardened steels and abrasive alloys. The 1/8 inch shank diameter and 1-1/2 inch overall length suit it to standard collet toolholding setups on CNC machining centers.

This end mill is used in precision CNC milling applications where small-diameter tooling is required. Typical applications include micro-slot milling, fine-detail contouring, and tight-pocket roughing in hard metals, stainless steel, titanium, and similar materials. It is a single-end, right-hand cut, right-hand flute tool suited to professional machinists and tool-and-die shops running light radial engagement passes at elevated spindle speeds. The center-cutting design allows direct plunge entry where needed.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard-material applications
• AlTiN coating provides high thermal resistance, extending tool life in dry and high-speed cutting
• Variable helix design reduces chatter and improves surface finish
• Three-flute geometry balances chip evacuation with cutting strength at small diameters
• Center-cutting capable, allowing direct plunge into workpiece material
• Right-hand cut and right-hand flute orientation for standard CNC spindle compatibility

Compatibility

Designed as a small-diameter solid carbide end mill for use in CNC machining centers and high-speed milling machines equipped with 1/8 inch collet or toolholder systems.

Installation Notes

Installation and tool changes should be performed by qualified machinists with the spindle fully stopped and the machine in a safe, locked-out state. Seat the 1/8 inch shank fully into the collet or toolholder and torque the retention nut per the toolholder manufacturer specifications. At this diameter, runout control is critical — verify TIR with a dial indicator before beginning the cut. Do not exceed the tool manufacturer recommended cutting parameters for feed rate, depth of cut, or spindle speed.
