Harvey Tool 942312-C8 3/16 in Square End Mill Solid Carbide

Product Description

The HARVEY TOOL 942312-C8 is a solid carbide square end mill designed for precision milling in demanding shop environments. With a 3/16 inch cutting diameter and a 9/16 inch length of cut, this single-end tool delivers clean, accurate results in ferrous and non-ferrous materials. The TiB2 (Titanium Diboride) coating reduces friction and improves tool life in high-speed applications. Three flutes with a 42-degree variable helix angle optimize chip evacuation and reduce chatter during cutting operations. This tool is installed and operated by machinists, tool-and-die makers, and CNC programmers working in production or prototype environments.

This end mill is suited for light to medium milling passes in applications where precise dimensional control is required. The variable helix geometry makes it particularly effective in thin-wall and finishing operations where vibration and deflection must be minimized. The right-hand cutting and right-hand flute direction are standard for conventional CNC machining center setups. The 3/16 inch shank diameter matches the cutting diameter, and the 2 inch overall length keeps the tool rigid in close-tolerance work. It is centercutting, allowing plunge entry directly into the workpiece without pre-drilling.

Key Features

• 3/16 inch cutting diameter with matching 3/16 inch shank for direct collet or chuck mounting
• Solid carbide construction for rigidity and wear resistance at elevated cutting speeds
• TiB2 (Titanium Diboride) coating reduces built-up edge and extends tool life
• 42-degree variable helix reduces harmonic vibration and improves surface finish
• Centercutting design permits direct plunge milling without a pilot hole
• Three-flute configuration balances chip clearance with cutting edge strength

Compatibility

Designed as a standard square end mill for use in CNC machining centers, manual mills, and multi-axis equipment accepting 3/16 inch collets or end mill holders.

Installation Notes

This end mill is installed by machinists using a collet chuck, ER collet system, or end mill holder rated for the 3/16 inch shank diameter. Ensure the machine spindle and toolholder are clean and free of debris before seating the shank. Set appropriate cutting parameters for the workpiece material and confirm runout with a dial indicator before production cuts. Always follow machine guarding and PPE requirements per shop safety standards.
