Value Collection 723-4454 Roughing End Mill 1/2 in Cobalt

Product Description

The VALUE COLLECTION 723-4454 is a single-end roughing end mill designed for aggressive material removal in milling applications. Built from M42 cobalt high-speed steel with a bright, uncoated finish, this tool handles tough ferrous and non-ferrous metals where standard HSS tooling would wear prematurely. The 3-flute design balances chip evacuation with rigidity, making it suitable for roughing passes where feed rates and depth of cut matter more than surface finish. At 0.5 inches in diameter with a 1-inch length of cut and 3-inch overall length, it fits standard tool holders used across vertical and horizontal machining centers.

This end mill is suited for machine shops, tool rooms, and production environments where roughing operations on steel, stainless, cast iron, or high-temperature alloys are routine. The right-hand cutting direction and right-hand flute geometry are standard configurations compatible with conventional milling setups. The centercutting design allows plunge entry, adding flexibility when the operation calls for it. A high helix style promotes efficient chip flow during heavy cuts.

Key Features

• M42 cobalt HSS construction for heat and wear resistance in tough materials
• 3-flute roughing geometry for aggressive stock removal with controlled chip load
• Centercutting capable for direct plunge operations
• High helix style improves chip evacuation during deep roughing passes
• Bright, uncoated finish suitable for dry cutting or use with standard cutting fluids
• Right-hand cut and right-hand flute direction for conventional milling compatibility

Compatibility

Designed as a standard single-end roughing end mill with a 0.5-inch shank diameter, compatible with 1/2-inch collets, end mill holders, and milling chucks used in vertical machining centers, knee mills, and similar setups.

Installation Notes

Installation is performed by machinists using a compatible tool holder and collet or end mill holder torqued per the machine manufacturer specification. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Confirm runout with a dial indicator after seating; excessive runout accelerates edge wear on roughing geometry. Follow shop-standard speeds and feeds for cobalt HSS tooling based on workpiece material and depth of cut.
