Value Collection 723-4424 Roughing End Mill 5/16 in Cobalt

Product Description

The VALUE COLLECTION 723-4424 is a single-end roughing end mill designed for aggressive material removal in milling applications. Manufactured from M42 cobalt high-speed steel with a bright, uncoated finish, this end mill offers strong heat and wear resistance for demanding cuts. The 5/16-inch (0.3125-inch) cutting diameter pairs with a 3/8-inch shank diameter and a 1-3/8-inch (1.375-inch) length of cut, giving machinists a compact, rigid tool suited for roughing passes in ferrous and non-ferrous materials. Overall length is 3-1/8 inches. It is center-cutting and configured for right-hand cutting and right-hand flute direction with a high helix style.

This roughing end mill is intended for use in CNC machining centers, manual mills, and knee mills in both job shop and production environments. The 3-flute geometry reduces chip load per tooth while maintaining a fast metal removal rate, making it practical for slotting, profiling, and pocketing operations where stock removal speed matters. It is installed and used by machinists and tool-and-die professionals working with a range of workpiece materials where a cobalt HSS tool grade is appropriate.

Key Features

• M42 cobalt high-speed steel construction for elevated heat and wear resistance
• 3-flute design balances chip evacuation with material removal efficiency
• Center-cutting capability allows direct plunge entry into workpiece
• High helix style promotes smooth chip flow and reduced cutting forces
• Right-hand cut and right-hand flute direction for standard spindle operation
• Bright, uncoated finish suitable for a wide range of general milling applications

Compatibility

Designed as an OEM-style single-end roughing end mill compatible with standard 3/8-inch collets, end mill holders, and milling chucks used in CNC and manual milling machines.

Installation Notes

Installation is performed by machinists using an appropriate tool holder torqued to the machine manufacturer's specifications. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Verify shank diameter matches the collet or holder bore before clamping. Inspect the tool for runout after mounting to ensure dimensional accuracy during the cut.
