Harvey Tool 834214-C3 Square End Mill 7/32 in 4 Flute Carbide

Product Description

The HARVEY TOOL 834214-C3 is a solid carbide square end mill designed for precision milling operations in metalworking and machining applications. It features a 7/32 inch (0.2187 inch) cutting diameter, a 1-1/8 inch (1.125 inch) length of cut, and a 4 inch overall length. The tool carries an AlTiN (Aluminum Titanium Nitride) coating that improves heat resistance and extends tool life in ferrous and hardened materials. With 4 flutes and a 30-degree helix angle, it delivers efficient chip evacuation and a smooth cutting action. This end mill is centercutting, enabling direct plunge entry into the workpiece without a pre-drilled hole.

This end mill is suited for milling slots, pockets, and profiles in ferrous metals, alloys, and hardened steels in both production and job-shop environments. The 1/4 inch shank diameter fits standard collets and tool holders commonly used on CNC machining centers, knee mills, and manual milling machines. It is a single-end design, meaning the tool is replaced when the cutting end is worn rather than indexed. Machinists working in aerospace, die and mold, or general precision machining will find this tool appropriate for finishing and semi-finishing passes.

Key Features

• Solid carbide construction for rigidity and wear resistance in demanding materials
• AlTiN coating improves thermal resistance and reduces built-up edge in ferrous applications
• 4 flutes with a 30-degree helix angle for balanced chip load and surface finish
• Centercutting geometry allows direct plunge milling without a pilot hole
• Right-hand cut and right-hand flute configuration for standard spindle direction
• 1/4 inch shank fits common collets and end mill holders

Compatibility

Designed as an OEM-style replacement or direct-fit solid carbide end mill for use in any CNC or manual milling machine equipped with a 1/4 inch collet or end mill holder.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer's guidelines. Ensure the spindle is fully stopped and the machine is powered off before changing tooling. Seat the shank fully into the collet or holder and torque the retention mechanism according to the toolholder manufacturer's specification. Verify runout with a dial indicator before commencing a cut to avoid premature tool wear or workpiece damage.
