Value Collection 724-6403 Roughing End Mill 3/16 in Cobalt

Product Description

The VALUE COLLECTION 724-6403 is a single-end roughing end mill designed for aggressive material removal in milling applications. Built from M42 cobalt high-speed steel and finished with a TiN coating, it delivers solid wear resistance and heat tolerance during heavy cuts. The 3/16-inch diameter cutting head features 3 flutes with a high-helix, right-hand spiral configuration. The 1/2-inch length of cut suits shallow-to-moderate roughing passes, while the 2-3/8-inch overall length fits standard milling chucks. The center-cutting design allows plunge entry. This tool is suited for machinists and tool-and-die professionals working on ferrous and non-ferrous workpieces.

This roughing end mill is intended for use in vertical milling machines, CNC machining centers, and manual knee mills. It is typically applied to roughing passes where stock removal rate takes priority over surface finish. The 3/8-inch shank diameter is compatible with standard ER collet chucks and end mill holders commonly found in job shop and production environments. The TiN coating extends tool life on steels, cast iron, and similar materials.

Key Features

• M42 cobalt HSS construction for improved heat and wear resistance over standard M2 tooling
• TiN coating reduces friction and extends cutting edge life
• 3 flutes with high-helix, right-hand cut and right-hand flute direction for efficient chip evacuation
• Center-cutting geometry allows direct plunge entry without pre-drilling
• 3/8-inch shank diameter fits standard collet chucks and end mill holders
• Single-end design with 1/2-inch length of cut and 2-3/8-inch overall length

Compatibility

Designed as an OEM-style replacement or standard tooling option for milling machines and machining centers that accept a 3/8-inch shank end mill.

Installation Notes

Installation is performed by qualified machinists or toolroom personnel. Secure the shank fully into the collet or end mill holder to the recommended engagement depth and torque the retention mechanism per the toolholder manufacturer guidelines. Verify spindle runout before beginning the cut. Do not exceed the recommended depth of cut or feed rate for the workpiece material and machine rigidity.
