Value Collection 724-3140 Roughing End Mill 5/8 in Cobalt

Product Description

The VALUE COLLECTION 724-3140 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 (titanium nitride) coating, it handles tough ferrous and non-ferrous materials where standard HSS tooling falls short. The 5/8-inch diameter, 4-flute configuration with a right-hand cut and right-hand flute direction makes it a practical choice for roughing passes on manual mills and CNC machining centers. Machinists and tool-and-die professionals typically reach for this style of end mill when pre-finishing stock removal speed matters more than surface finish.

This roughing end mill is suited for general-purpose shop use across job shops, maintenance machining, and production environments. The 5/8-inch shank matches the cutter diameter, making it compatible with standard collet chucks, end mill holders, and milling machine spindles of the same bore size. The 3/4-inch length of cut and 2-7/8-inch overall length position it for shallow-to-moderate depth roughing applications where extended reach is not required. It is not center-cutting, so plunge milling is not recommended without a pre-drilled entry hole.

Key Features

• M42 cobalt construction for improved heat and wear resistance over standard HSS
• TiN coating reduces friction and extends tool life in ferrous materials
• 4-flute, single-end design optimized for roughing and bulk material removal
• Right-hand cut and right-hand flute direction for conventional milling setups
• 5/8-inch shank diameter matches cutter diameter for straightforward toolholding
• Not center-cutting — suited for peripheral and slot milling with pre-drilled entry

Compatibility

Designed as an OEM-style replacement or direct-use roughing end mill for standard milling machines and CNC machining centers accepting 5/8-inch bore end mill holders or collet chucks.

Installation Notes

Installation and tool changes must be performed with the machine powered down and the spindle fully stopped. Seat the shank fully into the toolholder and torque the retention screw or collet nut per the toolholder manufacturer's specification. Inspect the cutting edges and TiN coating for chips or wear before each use. Because this end mill is not center-cutting, begin cuts from the workpiece edge or use a pre-drilled hole to avoid damaging the tool tip.
