Value Collection 724-0077 Roughing End Mill 3/8 in Cobalt

Product Description

The VALUE COLLECTION 724-0077 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 delivers durability and heat resistance during heavy-duty cuts. The 3/8-inch diameter cutter features four flutes with a right-hand cutting and right-hand flute direction, and it is center-cutting, allowing plunge entry into a workpiece. With a 3/4-inch length of cut and a 2.5-inch overall length, this end mill suits standard milling machine and CNC machining center setups where roughing passes are required before finishing.

This roughing end mill is suited for use in job shops, tool rooms, and production environments where rapid stock removal on steel, stainless steel, and high-temperature alloys is the priority. Its cobalt M42 construction makes it particularly effective when cutting harder or abrasive materials that would accelerate wear in standard high-speed steel tooling. It is a single-piece, solid-body tool installed directly into a collet, end mill holder, or compatible toolholder with a 3/8-inch bore.

Key Features

• M42 cobalt high-speed steel construction for elevated heat and wear resistance
• Four flutes with right-hand cut and right-hand helix for efficient chip evacuation
• Center-cutting geometry allows direct plunge milling without pre-drilled pilot holes
• Bright, uncoated finish suitable for a wide range of ferrous and non-ferrous materials
• 3/8-inch shank diameter matches mill diameter for direct collet or holder mounting
• Single-end design with 3/4-inch length of cut and 2.5-inch overall length

Compatibility

Designed as a direct-fit roughing end mill for any milling machine or CNC machining center accepting a 3/8-inch shank toolholder or collet.

Installation Notes

Installation is performed by a machinist or CNC operator using an appropriate collet or end mill holder rated for a 3/8-inch shank. Ensure the machine spindle is fully stopped and locked out before changing tooling. Confirm shank engagement depth meets the toolholder manufacturer minimum to prevent pullout under roughing loads. Inspect the collet and holder for runout before beginning cuts.
