Value Collection 723-4406 Roughing End Mill 1/4 in Cobalt

Product Description

The VALUE COLLECTION 723-4406 is a single-end cobalt roughing end mill designed for aggressive material removal in milling operations. Built from M42 cobalt high-speed steel, it handles tough ferrous and non-ferrous metals where standard HSS tooling wears prematurely. The 1/4 inch cutting diameter, 3-flute geometry, and high-helix flute design work together to evacuate chips quickly and reduce heat buildup at the cutting zone. At 0.625 inches length of cut and 2-7/16 inches overall length, this tool fits standard CNC machining centers and manual knee mills. The bright uncoated finish suits applications where coating interaction with certain materials is a concern.

This roughing end mill is suited for general-purpose roughing passes in job shop, toolroom, and production environments. The right-hand cutting direction and right-hand flute spiral are the standard configuration for conventional and climb milling on vertical machining centers. Center-cutting capability allows plunge entry without a pre-drilled pilot hole, adding flexibility for pocket work. Machinists, tool and die makers, and CNC operators working in steel, stainless, and similar alloys will find this tool a practical choice for roughing stages before finishing passes.

Key Features

• M42 cobalt construction for improved heat and wear resistance over standard HSS
• 3-flute, high-helix geometry promotes efficient chip evacuation during roughing
• Center-cutting design allows direct plunge entry into workpiece material
• Right-hand cut and right-hand flute direction for standard mill setups
• Bright uncoated finish compatible with a wide range of materials and cutting fluids
• Single-end configuration with 3/8 inch shank diameter for secure collet or end mill holder grip

Compatibility

Designed as a standard roughing end mill replacement for use in any machine tool accepting a 3/8 inch shank, including CNC vertical machining centers, manual mills, and drill-mill setups.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Seat the shank fully in the collet or end mill holder to the recommended minimum engagement depth per the toolholder manufacturer. Verify runout with a dial indicator before beginning cuts, as excessive runout accelerates tool wear and reduces surface finish quality.
