Value Collection 723-5728 Roughing End Mill 15/32 in Cobalt

Product Description

The VALUE COLLECTION 723-5728 is a single-end cobalt roughing end mill designed for aggressive material removal in milling operations. Built from M42 cobalt high-speed steel, this end mill handles harder workpiece materials and elevated cutting temperatures better than standard HSS tooling. It features a 15/32-inch (0.4688 inch) cutting diameter, a 1.25-inch length of cut, and a 1/2-inch straight shank. The bright, uncoated finish is standard for cobalt roughing tools used in general-purpose shop environments. With 4 right-hand flutes and a right-hand cutting direction, it delivers efficient chip evacuation during roughing passes on mills and machining centers.

This roughing end mill suits metalworking applications in job shops, toolrooms, and production environments. It is used for roughing passes on ferrous metals, stainless steel, and harder alloys where heat resistance at the cutting edge is required. The single-end configuration and non-centercutting geometry make it appropriate for peripheral milling, slotting, and side milling operations. Licensed machinists and CNC operators are the primary users of this tooling in manual and CNC vertical milling setups.

Key Features

• M42 cobalt HSS construction for increased heat and wear resistance over standard HSS
• 15/32-inch (0.4688 inch) cutting diameter with 1.25-inch length of cut
• 1/2-inch shank diameter for standard R8, ER, or side-lock toolholders
• 4-flute right-hand cut and right-hand flute geometry for efficient chip removal
• Bright, uncoated finish — ready to run or accept aftermarket coating
• Non-centercutting design intended for peripheral and side milling operations

Compatibility

Designed as a direct-fit replacement or standard tooling option for any vertical mill or machining center accepting a 1/2-inch shank end mill. Compatible with R8 collets, ER collet chucks, and side-lock holders sized for 1/2-inch shank tooling.

Installation Notes

Installation is performed by qualified machinists following standard toolholding procedures. Ensure the machine spindle is fully stopped and the power is locked out before changing tooling. Seat the shank fully into the collet or holder and torque the drawbar or nut to the toolholder manufacturer specification. Non-centercutting geometry means this tool cannot plunge directly into solid material — use a pre-drilled entry point or ramp entry when required.
