Value Collection 724-4266 Roughing Finishing End Mill

Product Description

The VALUE COLLECTION 724-4266 is a single-end roughing finishing end mill designed for aggressive material removal and finish passes in one tool. Built from M42 cobalt high-speed steel, it handles tough ferrous and heat-resistant alloys without coating. The 1 inch diameter, 5-flute geometry with a 30-degree helix angle produces efficient chip evacuation while maintaining surface finish quality. The square end profile suits shoulder milling, slotting, and profiling operations. Machinists and tool-and-die professionals use this style of end mill on manual knee mills and CNC machining centers alike.

This end mill is suited for general-purpose milling in job shops, maintenance machining environments, and production setups where a cobalt uncoated tool is specified. The Weldon flat shank provides positive drive and resists pullout in standard set-screw holders. With a 3 inch length of cut and 5.5 inch overall length, it reaches deeper pockets and stepped features without requiring extended-reach tooling. Right-hand cutting direction and right-hand flute spiral are standard for conventional and climb milling on most vertical mill spindles.

Key Features

• M42 cobalt construction for heat resistance in hard and tough materials
• 5-flute design balances chip load per tooth with rigidity for finishing passes
• 30-degree helix angle promotes smooth cutting action and chip flow
• Weldon flat shank prevents rotational slippage in set-screw tool holders
• Square end geometry supports shoulder milling, slotting, and contour profiling
• Bright/uncoated finish compatible with oil-based and soluble cutting fluids

Compatibility

Designed as an OEM-style replacement or direct-use roughing finishing end mill for standard 1 inch bore milling chucks and Weldon-flat set-screw holders on vertical machining centers and knee mills.

Installation Notes

Installation is performed by qualified machinists following standard toolroom practices. Ensure the spindle is fully powered down and locked before changing tooling. Seat the Weldon flat against the set screw and torque the holder per the tool holder manufacturer specification. Verify runout with a dial indicator before taking the first cut, as excessive runout accelerates edge wear on multi-flute end mills.
