Value Collection 724-1086 Roughing End Mill 3/8 in Cobalt

Product Description

The VALUE COLLECTION 724-1086 is a single-end cobalt roughing end mill designed for aggressive material removal in milling applications. Built from M42 cobalt high-speed steel and finished with a TiN (titanium nitride) coating, this tool delivers added wear resistance and extended cutting life compared to standard HSS end mills. It features a 3/8 inch diameter with four right-hand flutes, a 1-1/8 inch length of cut, and a 2-15/16 inch overall length. The centercutting geometry allows plunge cutting as well as peripheral milling. Machinists and tool-and-die professionals reach for roughing end mills when rapid stock removal is the priority before a finishing pass.

This end mill is suited for use in manual knee mills, CNC machining centers, and benchtop milling machines where a 3/8 inch straight shank toolholder or collet is available. The right-hand cutting direction and right-hand flute spiral are standard for conventional and climb milling on ferrous and non-ferrous materials. The TiN coating makes it especially effective on alloy steels, tool steels, and cast iron where heat buildup and abrasion accelerate tool wear. The 3/8 inch shank diameter matches the cutting diameter for direct collet clamping without a reduction sleeve.

Key Features

• M42 cobalt HSS construction for improved hardness and heat resistance over standard HSS
• TiN coating reduces friction and extends tool life in abrasive materials
• Centercutting design supports both plunge and peripheral cutting operations
• Right-hand cut, right-hand flute orientation for standard milling setups
• Four flutes with roughing geometry for high-volume chip removal
• Single-end configuration with a 3/8 inch shank for direct collet or endmill holder mounting

Compatibility

Designed as an OEM-style replacement or standard tooling option for any milling setup accepting a 3/8 inch straight-shank end mill in a collet chuck or end mill holder.

Installation Notes

Installation is performed by a machinist or toolroom technician using a collet chuck or end mill holder rated for the 3/8 inch shank diameter. Ensure the machine spindle is fully stopped and locked before inserting or removing the tool. Verify runout with a dial indicator after clamping, as excessive runout accelerates wear on roughing geometry. Always confirm feed rate and speed settings are appropriate for the workpiece material before beginning a cut.
