Value Collection 724-1143 Roughing End Mill 5/8in Cobalt

Product Description

The VALUE COLLECTION 724-1143 is a single-end roughing end mill designed for aggressive material removal in milling applications. Built from M42 cobalt high-speed steel with a TiN (titanium nitride) coating, it handles tough ferrous and non-ferrous materials with improved heat and wear resistance. The cutter measures 0.625 inches in diameter with a 1.25-inch length of cut and a 3-3/8-inch overall length. Four right-hand flutes with a roughing profile break chips into smaller segments, reducing cutting forces and allowing higher feed rates compared to standard end mills. Center-cutting geometry allows plunge entry into the workpiece.

This roughing end mill is suited for general machining operations including slotting, profiling, and pocketing on manual mills and CNC machining centers. It is commonly used in job shops, maintenance machining, and production environments where rapid stock removal is prioritized before a finish pass. The 5/8-inch shank diameter matches the mill diameter, making it compatible with standard collet chucks and end mill holders of that bore size. Right-hand cutting direction supports conventional and climb milling setups.

Key Features

• M42 cobalt construction for elevated heat resistance and hardness retention during heavy cuts
• TiN coating extends tool life and reduces built-up edge on ferrous materials
• 4-flute roughing geometry breaks chips and lowers cutting pressure at high feed rates
• Center-cutting design allows direct plunge milling without a pre-drilled entry hole
• Right-hand flute and cut direction for standard spindle rotation
• Matched shank and cutter diameter at 0.625 inches for straightforward toolholder setup

Compatibility

Designed as an OEM-style replacement or standard tooling option for milling machines accepting a 5/8-inch bore end mill holder or collet chuck.

Installation Notes

Installation is performed by a machinist or tooling technician. Power down and lock out the machine spindle before inserting or removing any cutting tool. Seat the shank fully into the collet or end mill holder and torque the retention mechanism according to the toolholder manufacturer specifications. Inspect the cutting edges for chips or wear before each use, and verify spindle speed and feed rate are appropriate for the workpiece material before engaging the cut.
