Value Collection 724-6430 Roughing End Mill 3/8 in Cobalt

Product Description

The VALUE COLLECTION 724-6430 is a single-end roughing end mill designed for aggressive material removal in milling operations. Built from M42 cobalt high-speed steel and coated with titanium nitride (TiN), this tool delivers improved wear resistance and heat tolerance compared to standard HSS tooling. The 3-flute, right-hand cutting geometry with a high-helix flute direction promotes efficient chip evacuation and reduces chatter during roughing passes. Center-cutting capability allows plunge milling as well as conventional peripheral cuts. At 0.375 inches in diameter with a 0.4375-inch length of cut and a 2.1875-inch overall length, it suits tight-tolerance work in a variety of materials.

This end mill is suited for use on manual knee mills, CNC machining centers, and benchtop mills where roughing passes precede finish milling. It is commonly applied to ferrous metals, alloy steels, and stainless steels where cobalt tooling outperforms standard HSS. Machinists, toolroom operators, and job shop technicians working in both production and prototype environments will find this a practical single-end roughing option for 3/8-inch applications.

Key Features

• M42 cobalt construction for elevated heat and wear resistance
• TiN coating extends tool life and reduces friction at the cutting edge
• 3-flute, high-helix right-hand geometry promotes fast chip evacuation
• Center-cutting design allows plunge entry without a pilot hole
• 3/8-inch shank diameter matches standard collets and end mill holders
• Single-end configuration for straightforward tool changes

Compatibility

Designed as an OEM-style replacement or direct addition for standard 3/8-inch end mill holders, ER collet chucks, and side-lock arbors used on manual and CNC milling machines.

Installation Notes

Installation is performed by machinists or toolroom technicians using an appropriate collet, end mill holder, or side-lock arbor sized for a 3/8-inch shank. Ensure the machine spindle is fully stopped and locked before changing tooling. Verify tool runout with a dial indicator after securing the end mill, and confirm cutting parameters are appropriate for the workpiece material before engaging the cut.
