Value Collection 723-4478 Roughing End Mill 5/8 in Cobalt

Product Description

The VALUE COLLECTION 723-4478 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 3-flute, right-hand cutting geometry with a high helix style promotes efficient chip evacuation and reduces chatter during heavy cuts. Center-cutting capability allows the tool to plunge directly into the workpiece without a pre-drilled entry hole. Machinists and tooling specialists install this end mill in CNC and manual milling machines for roughing passes on ferrous and non-ferrous materials.

This roughing end mill is suited for use in job shops, manufacturing facilities, and maintenance environments where material needs to be removed quickly before a finish pass. The 0.625-inch shank diameter matches the mill diameter, making it compatible with standard 5/8-inch collets and end mill holders. The M42 cobalt construction provides added heat and wear resistance compared to standard M2 high-speed steel, making it a practical choice for harder workpiece materials or interrupted cuts where tool longevity matters.

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 passes
• Center-cutting design allows direct plunge entry without a pilot hole
• Right-hand cut and right-hand flute direction for use in standard milling setups
• Bright, uncoated finish suitable for general-purpose roughing applications
• Single-end configuration with 0.625-inch shank for use in standard collet systems

Compatibility

Designed as a general-purpose roughing end mill compatible with standard 5/8-inch collet chucks and end mill holders used in CNC and manual milling machines.

Installation Notes

Installation is performed by qualified machinists or tooling technicians. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Seat the shank fully in the collet or holder and torque the drawbar or set screws according to the machine manufacturer specifications. Always verify runout with a dial indicator before beginning a cut to maximize tool life and part accuracy.
