Value Collection 724-2290 Roughing End Mill 1-1/4 in Cobalt

Product Description

The VALUE COLLECTION 724-2290 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 heat resistance and edge retention in demanding cutting applications. The tool measures 1.25 inches in diameter with a 0.75-inch shank diameter, a 2-inch length of cut, and a 4.25-inch overall length. With 6 flutes and a right-hand cutting and flute direction, this roughing end mill is suited for machinists and toolroom professionals running production or job-shop milling work.

This roughing end mill is intended for use on manual mills and CNC machining centers where rapid stock removal is the priority. The 6-flute geometry distributes chip load across multiple cutting edges, making it effective on ferrous metals and other materials where cobalt tooling is the standard choice. It is a single-end, non-centercutting tool, meaning it is used for peripheral and slotting passes rather than plunge cuts. Typical applications include roughing passes on steel, stainless, and high-temperature alloys in both prototype and production environments.

Key Features

• M42 cobalt construction provides elevated red hardness for cutting ferrous and hard materials
• 6 flutes for increased chip load distribution and faster material removal rates
• 1.25-inch milling diameter with a 0.75-inch shank for rigid toolholder engagement
• 2-inch length of cut accommodates moderate-depth roughing passes
• Right-hand cut and right-hand flute direction for standard spindle rotation
• Bright/uncoated finish suitable for use with or without cutting fluid

Compatibility

Designed as an OEM-style replacement or standard tooling selection for milling machines and CNC machining centers accepting a 3/4-inch shank end mill holder or collet chuck.

Installation Notes

Installation and tool changes must be performed with the machine spindle fully stopped and the machine powered down or in an e-stop state. Secure the 0.75-inch shank in a properly sized end mill holder or collet chuck to the torque specification recommended by the toolholder manufacturer. As a non-centercutting tool, avoid programming direct plunge moves into solid material. A licensed machinist or qualified CNC operator should verify speeds and feeds based on workpiece material prior to running production cuts.
