Value Collection 724-1146 Roughing End Mill 5/8 in Cobalt

Product Description

The VALUE COLLECTION 724-1146 is a single-end roughing end mill designed for aggressive material removal in milling operations. Built from M42 cobalt high-speed steel and finished with a TiN coating, this tool handles tough ferrous and non-ferrous materials with extended tool life compared to standard HSS. The 5/8 inch diameter cutter features 4 right-hand flutes with a right-hand cutting direction, a 1-5/8 inch length of cut, and a 3-3/4 inch overall length. Centercutting capability allows for plunge entry. Machinists and tool-and-die professionals working on manual mills or CNC equipment use this end mill for roughing passes where high material removal rate is the priority.

This roughing end mill is suited for roughing operations in job shops, production machining environments, and maintenance repair facilities. The serrated or wave-form flute geometry typical of roughing end mills reduces cutting forces and chip load per tooth, making it effective on steel, stainless, and other hard alloys. The 5/8 inch shank diameter matches the cutter diameter, fitting standard R8, CAT, BT, and ER collet toolholders of the appropriate bore size.

Key Features

• M42 cobalt HSS construction for elevated heat and wear resistance
• TiN coating extends cutting life and reduces friction during heavy roughing
• 4 right-hand flutes with right-hand cutting direction
• Centercutting design allows direct plunge milling
• 1-5/8 inch length of cut accommodates moderate-depth roughing passes
• Single-end configuration with 5/8 inch shank for direct toolholder mounting

Compatibility

Designed as a standard-shank roughing end mill compatible with any milling toolholder accepting a 5/8 inch straight shank, including R8 collets, ER collet chucks, and side-lock end mill holders used on vertical mills and CNC machining centers.

Installation Notes

Installation is performed by a machinist or toolroom technician using an appropriate collet or end mill holder rated for the 5/8 inch shank diameter. Ensure the spindle is fully powered down and locked before changing tooling. Seat the shank to the full recommended engagement depth in the holder and torque the drawbar or collet nut to the toolholder specification before initiating a cut. Inspect the TiN coating and cutting edges for chipping before each use.
