Value Collection 723-4469 Roughing End Mill 1/2 in 3 Flute Cobalt

Product Description

The VALUE COLLECTION 723-4469 is a single-end cobalt roughing end mill designed for aggressive material removal in milling operations. Built from M42 cobalt high-speed steel with a bright, uncoated finish, it delivers the heat resistance and toughness needed for interrupted cuts and hard-to-machine materials. The 1/2-inch diameter cutting head features 3 flutes with a high helix style and right-hand cutting and flute direction. With a 3-inch length of cut and 5-inch overall length, this tool handles moderate-depth roughing passes in a standard end mill holder. Machinists and tool-and-die professionals reach for this style of end mill when rapid stock removal is the priority.

This roughing end mill is suited for use in vertical machining centers, knee mills, and manual milling machines. The centercutting geometry allows plunge entry, adding flexibility to the machining workflow. The M42 cobalt grade performs well on alloy steels, stainless steels, cast iron, and other abrasion-resistant materials. The bright, uncoated surface is appropriate for use with cutting fluids and is a practical choice in shops that regrind tooling, since the absence of coating does not complicate resharpening.

Key Features

• M42 cobalt high-speed steel construction for heat and wear resistance
• 3-flute, high helix design promotes efficient chip evacuation during roughing passes
• Centercutting geometry enables direct plunge entry without pre-drilling
• Right-hand cutting and right-hand flute direction for standard spindle operation
• Bright, uncoated finish is compatible with cutting fluids and supports regrinding
• Single-end configuration with 1/2-inch shank for secure tool holding

Compatibility

Designed as a standard 1/2-inch shank roughing end mill for use in any tool holder or collet chuck accepting a 1/2-inch straight shank, including ER collets, end mill holders, and set-screw-style holders on vertical and horizontal milling machines.

Installation Notes

Installation is performed by a machinist or toolroom technician. Ensure the machine spindle is fully stopped and locked out before changing tooling. Clean the shank and tool holder bore before seating the end mill to prevent runout. Tighten set screws or collet nuts to the tool holder specification and verify runout with a dial indicator before beginning a cut.
