Value Collection 723-6942 Roughing End Mill 5/16 in Cobalt

Product Description

The VALUE COLLECTION 723-6942 is a single-end roughing end mill designed for aggressive material removal in milling operations. Built from M42 cobalt high-speed steel with a TiN (titanium nitride) coating, this tool handles tough ferrous and non-ferrous workpiece materials while maintaining edge hardness under heat. The 5/16 inch (0.3125 inch) cutting diameter and 4-flute configuration with right-hand cutting and right-hand flute direction make it well-suited for roughing passes where chip clearance and feed rate matter. The overall length is 3-3/16 inches with a 1-3/8 inch length of cut. Machinists and tool-and-die trades install this type of end mill in CNC and manual vertical milling machines.

This roughing end mill is used in machine shops, maintenance facilities, and production environments where stock removal speed takes priority over finish quality. The 3/8 inch shank diameter fits standard ER collet chucks, end mill holders, and milling machine spindles commonly found in job shops. Non-centercutting geometry means this tool requires a pre-drilled or pre-milled entry point and is not intended for plunge cutting. It is appropriate for side milling, slot roughing, and profiling passes in steel, alloy steel, stainless, and similar materials.

Key Features

• M42 cobalt HSS construction resists heat buildup during high-feed roughing cuts
• TiN coating extends tool life and reduces friction on ferrous workpiece materials
• 4-flute, right-hand cut and right-hand helix geometry for efficient chip evacuation
• Single-end design with 1-3/8 inch length of cut and 3-3/16 inch overall length
• 3/8 inch shank diameter fits standard collet and end mill holder tooling systems
• Non-centercutting — requires pre-existing entry point; not suitable for plunge milling

Compatibility

Designed as an OEM-style replacement roughing end mill for use in standard milling machine spindles and CNC machining centers accepting a 3/8 inch shank diameter.

Installation Notes

Installation is performed by qualified machinists following shop safety protocols. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Secure the shank to the specified torque range recommended by the toolholder manufacturer. Verify runout with a dial indicator after installation to confirm proper seating before beginning a cut.
