Value Collection 724-0122 Roughing End Mill 1/2 in Cobalt

Product Description

The VALUE COLLECTION 724-0122 is a single-end roughing end mill designed for aggressive material removal in milling applications. Built from M42 cobalt high-speed steel with a bright, uncoated finish, it delivers the toughness needed for cutting harder workpiece materials. The cutter measures 1/2 inch in diameter with a 2-inch length of cut and a 4-inch overall length. Four right-hand flutes with a right-hand cutting direction combine with a center-cutting design, allowing plunge entry as well as standard peripheral milling. Machinists and toolroom professionals use roughing end mills like this one to remove stock rapidly before a finishing pass.

This end mill is suited for use in manual knee mills, CNC machining centers, and bridgeport-style machines handling ferrous and harder non-ferrous materials. The 1/2-inch shank diameter fits standard ER collet chucks, end mill holders, and Weldon-style side-lock holders common in production and job-shop environments. The cobalt M42 substrate makes it a practical choice when cutting stainless steel, alloy steel, and other materials that generate significant heat at the cutting edge. It ships as a single unit.

Key Features

• M42 cobalt high-speed steel substrate for heat resistance and edge retention in hard materials
• 4 right-hand flutes for efficient chip evacuation during roughing passes
• Center-cutting geometry allows direct plunge entry without a pilot hole
• 1/2-inch diameter shank matches the cutter diameter, compatible with standard 1/2-inch toolholding
• Bright, uncoated finish suitable for use with cutting fluids on a wide range of materials
• Single-end design; 2-inch length of cut accommodates moderate-depth slotting and profiling

Compatibility

Designed as an OEM-style replacement or direct-use roughing end mill for milling machines accepting 1/2-inch shank toolholders, including ER32 and ER40 collet systems and standard end mill holders.

Installation Notes

Installation is performed by qualified machinists following shop safety procedures. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Seat the shank fully into the holder to the recommended engagement depth and torque set screws or collet nuts per the toolholder manufacturer specifications. Confirm runout with a dial indicator before beginning a cut, and apply appropriate cutting fluid for the workpiece material.
