Value Collection 724-2128 Roughing End Mill 0.5in 4 Flute Cobalt

Product Description

The VALUE COLLECTION 724-2128 is a single-end roughing end mill designed for aggressive material removal in milling operations. Built from M42 cobalt high-speed steel, it offers strong heat and wear resistance across a range of ferrous and non-ferrous workpiece materials. The 0.5-inch diameter cutter features four flutes in a right-hand cutting and right-hand flute direction, with a bright, uncoated finish. The 3-inch length of cut and 5-inch overall length make it suited for deeper passes in standard milling setups. Machinists and tool-and-die professionals select this style of end mill when roughing operations call for high metal removal rates before a finishing pass.

This roughing end mill is used in vertical and horizontal milling machines, CNC machining centers, and manual knee mills across job shops, maintenance shops, and production environments. It is a single-end configuration, meaning cutting geometry is located on one end only. The 0.5-inch shank diameter matches standard collet and end mill holder sizes common in both imperial and metric tooling systems. The non-centercutting design is intended for peripheral cutting and side milling rather than plunge operations.

Key Features

• M42 cobalt HSS construction for elevated heat and abrasion resistance
• 4-flute geometry promotes chip evacuation during roughing passes
• Right-hand cut and right-hand flute direction for standard spindle operation
• Bright, uncoated finish suitable for use with cutting fluids
• 0.5-inch shank diameter fits standard collets and end mill holders
• Single-end design with 3-inch length of cut for deep-slot and side-mill applications

Compatibility

Designed as an OEM-style replacement or direct tooling option for standard 0.5-inch collet and end mill holder systems used in CNC and manual milling equipment.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer guidelines. Ensure the spindle is fully powered down and locked out before loading or removing the end mill. Secure the shank to the full recommended engagement depth in the collet or holder to prevent pullout under cutting loads. Verify spindle rotation direction matches the right-hand cutting direction of this tool before engaging the workpiece.
