Value Collection 724-0065 Roughing End Mill 3/8 in Cobalt

Product Description

The VALUE COLLECTION 724-0065 is a cobalt roughing end mill designed for aggressive material removal in milling applications. Built from M42 cobalt high-speed steel, this single-end, stub-length tool features a coarse pitch flute geometry that breaks chips efficiently and reduces heat buildup during heavy cuts. It measures 0.375 inches in diameter with a 0.375-inch length of cut and an overall length of 2.156 inches. The bright, uncoated finish suits a wide range of ferrous and non-ferrous workpiece materials. Machinists and tool-and-die professionals reach for this style of end mill when roughing slots, pockets, and profiles before a finishing pass.

This roughing end mill is suited for use on vertical and horizontal milling machines, CNC machining centers, and manual knee mills in job shop, maintenance, and production environments. The stub length profile provides added rigidity, making it appropriate for applications where tool deflection is a concern or where reach into the workpiece is limited. The right-hand cut and right-hand flute direction follow standard conventions for conventional and climb milling operations on common engineering materials.

Key Features

• M42 cobalt HSS construction for improved heat and wear resistance compared to standard M2 HSS
• Coarse pitch roughing geometry breaks chips and reduces cutting forces during heavy stock removal
• Center-cutting design allows plunge entry into the workpiece
• Stub length body increases rigidity and reduces deflection in short-reach applications
• Right-hand cut, right-hand helix flute orientation for standard milling setups
• Bright, uncoated finish compatible with a broad range of workpiece materials

Compatibility

Designed as an OEM-style replacement or direct-use roughing end mill for 3/8-inch collet or end mill holders on standard milling machines and machining centers accepting a 0.375-inch shank diameter.

Installation Notes

Installation and use should be performed by qualified machinists familiar with cutting tool safety and machine tool operation. Ensure the machine spindle is fully stopped and the power is locked out before inserting or removing the end mill from the holder. Verify collet or set-screw holder runout before beginning a cut, as excessive runout accelerates wear and can cause tool breakage. Follow the machine manufacturer and tooling supplier recommended speeds and feeds for cobalt end mills on the specific workpiece material being machined.
