Value Collection 724-3173 Roughing End Mill 3/4 in Cobalt

Product Description

The VALUE COLLECTION 724-3173 is a single-end roughing end mill designed for aggressive material removal in milling operations. Built from M42 cobalt high-speed steel with a TiN coating, this tool handles tough ferrous and non-ferrous materials while maintaining edge integrity under heat. It features 4 flutes in a right-hand cutting and right-hand flute direction, a 3/4 inch cutting diameter, and a 3/4 inch length of cut. The 3/4 inch shank diameter provides solid tool-holder engagement. Machinists and tool-and-die professionals use this end mill in vertical and horizontal milling machines for hogging stock before finish passes.

This roughing end mill is suited for general-purpose milling applications in job shops, production machining, and maintenance environments. The M42 cobalt substrate offers higher heat and wear resistance than standard M2 HSS, making it a practical choice when cutting alloy steels, stainless, and other difficult-to-machine materials. The non-centercutting geometry means plunge cutting is not recommended; use a ramp or helical entry instead. At 3 inches overall length, the tool fits standard short-reach setups with minimal overhang.

Key Features

• M42 cobalt steel construction for improved heat resistance over standard HSS
• TiN coating reduces friction and extends cutting edge life
• 4-flute, right-hand cut geometry optimized for roughing passes
• 3/4 inch shank diameter fits common ER and side-lock tool holders
• Non-centercutting design — requires ramp or helical entry, not direct plunge
• Single-end configuration for straightforward tool changes

Compatibility

Designed as a direct-fit roughing end mill for standard 3/4 inch ID milling chucks, ER collet systems, and side-lock holders used in vertical and horizontal knee mills and CNC machining centers.

Installation Notes

Installation is performed by qualified machinists following standard tooling procedures. Power down and lock out the machine spindle before seating or removing the tool. Verify holder runout with a dial indicator after clamping to minimize vibration and premature wear. Follow the machine manufacturer and ANSI B11 guidelines for safe tooling setup and operating speeds.
