Value Collection 724-2143 Roughing End Mill 5/8 in Cobalt

Product Description

The VALUE COLLECTION 724-2143 is a single-end roughing end mill designed for aggressive material removal in milling operations. Built from M42 cobalt high-speed steel with a bright, uncoated finish, it measures 0.625 inches in diameter with a 1.25-inch length of cut and a 3.375-inch overall length. The four-flute, right-hand cutting geometry with right-hand flute direction provides efficient chip evacuation during roughing passes. This tool is suited for machinists, tool-and-die workers, and production floor operators running manual mills or CNC machining centers where high-heat resistance and edge retention are required.

This roughing end mill is appropriate for use on ferrous and non-ferrous metals where rapid stock removal is the priority before a finishing pass. The 5/8-inch shank diameter matches the mill diameter, allowing direct clamping in standard collets or end mill holders without a reducer. It is not center-cutting, so it is not suitable for plunge entry. Typical applications include slot milling, shoulder milling, and profile roughing on steel, stainless steel, and similar alloys where cobalt tooling outperforms standard HSS under elevated cutting temperatures.

Key Features

• M42 cobalt construction for improved heat and wear resistance over standard HSS
• 4-flute right-hand cut geometry for effective chip removal during roughing passes
• 0.625-inch mill diameter with matching 0.625-inch shank for direct-fit clamping
• 1.25-inch length of cut suitable for moderate-depth roughing applications
• Bright, uncoated finish — compatible with cutting fluids and coolant systems
• Not center-cutting — requires a pre-drilled or pre-milled entry point

Compatibility

Designed as an OEM-style replacement or standard replacement roughing end mill for use in any manual or CNC milling machine accepting a 5/8-inch shank end mill holder or collet.

Installation Notes

Installation should be performed by a qualified machinist familiar with toolholder torque procedures and runout inspection. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the shank fully into the collet or end mill holder and torque the retention hardware per the toolholder manufacturer specifications. Confirm runout with a dial indicator before beginning the cut, and verify that entry strategy does not require plunge cutting, as this tool is not center-cutting.
