Harvey Tool 968832-C8 Square End Mill 1/2 in 3 Flute Carbide

Product Description

The HARVEY TOOL 968832-C8 is a solid carbide square end mill designed for high-performance milling in demanding metalworking and machining applications. It features a 1/2 inch cutting diameter, a 3/4 inch length of cut, and a 1/2 inch shank diameter with a 3 inch overall length. The 42-degree variable helix geometry reduces chatter and improves chip evacuation during interrupted cuts and deep pocketing. A TiB2 (titanium diboride) coating provides surface hardness and lubricity for extended tool life. Three flutes and a centercutting design allow for both peripheral and plunge cutting. This tool is installed and run by machinists and CNC operators in precision machine shops and production environments.

This end mill is suited for milling ferrous and non-ferrous materials where vibration control and finish quality are priorities. The right-hand cut, right-hand flute configuration is standard for conventional CNC machining centers and manual mills. The variable helix design makes it particularly effective in thin-wall, aerospace-grade aluminum, stainless steel, and hardened steel applications where harmonic chatter is a concern. The centercutting capability allows direct plunge entry without a pre-drilled pilot hole.

Key Features

• 42-degree variable helix reduces chatter and improves surface finish
• TiB2 coating increases surface hardness and reduces friction at the cutting edge
• Centercutting design enables direct plunge milling without a pilot hole
• Three-flute geometry balances chip clearance with rigidity for a 1/2 inch tool body
• Right-hand cut and right-hand flute configuration for standard CNC spindle operation
• Solid carbide construction provides stiffness and heat resistance over high-speed steel alternatives

Compatibility

Designed as an OEM-style replacement and standard production end mill compatible with 1/2 inch collets, end mill holders, and shrink-fit toolholders on CNC machining centers and manual vertical mills.

Installation Notes

Installation is performed by a machinist or CNC setup technician. Power down and lock out the spindle before changing tooling. Seat the shank fully into the holder to the recommended grip length and torque the retention mechanism per the toolholder manufacturer specification. Verify runout with a dial indicator after seating before beginning any cut.
