Value Collection 723-6731 Roughing End Mill 1/2 in Cobalt

Product Description

The VALUE COLLECTION 723-6731 is a single-end roughing end mill designed for aggressive material removal in milling operations. Built from M42 cobalt high-speed steel, it offers superior heat and wear resistance compared to standard HSS tooling. The 1/2 inch diameter cutter features 4 flutes with a right-hand cutting and right-hand flute direction, and carries a TiN (titanium nitride) coating to extend tool life. With a 5/8 inch length of cut and a 2-5/8 inch overall length, this tool suits a range of roughing passes on ferrous and non-ferrous workpieces. It is installed by machinists and tool-and-die professionals in CNC and manual milling setups.

This roughing end mill is suited for high-stock-removal operations in job shop, production, and maintenance machining environments. The corncob-style roughing profile reduces cutting forces and chip load per flute, making it effective on steel, stainless, and similar alloys. The 1/2 inch shank diameter matches standard R8, ER, and Weldon-style collet and holder systems commonly found in vertical milling machines and machining centers. This is a non-centercutting tool and is not intended for direct plunge cuts.

Key Features

• M42 cobalt HSS construction for elevated heat resistance and tool longevity in tough alloys
• TiN coating reduces friction and extends cutting edge life
• 4-flute, single-end configuration optimized for roughing passes and high material removal rates
• Right-hand cut and right-hand spiral flute direction for standard milling setups
• Non-centercutting design — requires a pre-drilled or ramped entry
• 1/2 inch shank diameter fits widely available collet and holder systems

Compatibility

Designed as an OEM-style replacement and general-use roughing end mill for standard 1/2 inch collet chucks, Weldon-style end mill holders, and ER collet systems used in vertical milling machines and machining centers.

Installation Notes

Installation is performed by a machinist using an appropriate end mill holder or collet chuck rated for the 1/2 inch shank diameter. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Verify runout with a dial indicator after seating the tool to minimize deflection and chatter during cut. This tool is non-centercutting — do not use for direct plunge milling without a pre-drilled hole or ramp entry.
