Value Collection 724-2179 Roughing End Mill 3/4 in Cobalt

Product Description

The VALUE COLLECTION 724-2179 is a single-end cobalt roughing end mill designed for aggressive material removal in milling operations. Built from M42 cobalt high-speed steel, it delivers the heat and wear resistance required for cutting harder ferrous and non-ferrous materials. The 3/4 inch diameter, 4-flute geometry with a right-hand cutting direction produces a coarse chip-breaking action that reduces tool pressure and heat buildup during heavy cuts. The bright, uncoated finish makes it straightforward to inspect for wear. This tool is a go-to for machinists and tool-and-die professionals running manual or CNC milling machines.

The 724-2179 is suited for roughing passes in shop and production environments where cycle time matters and fine surface finish is handled in a subsequent finishing pass. Its 1.25 inch length of cut and 3.5 inch overall length fit standard end mill holders and collet chucks found on vertical machining centers, knee mills, and bridgeports. Applications include slotting, profiling, and pocket milling in steel, alloy steel, cast iron, and similar materials. Non-centercutting geometry means this tool requires a pre-drilled starting point for plunge entry.

Key Features

• M42 cobalt HSS construction for improved heat resistance over standard M2 tooling
• 4-flute single-end design optimized for roughing and high-material-removal passes
• Right-hand cut and right-hand flute spiral for compatibility with standard spindle rotation
• Bright, uncoated finish for easy wear inspection and low-friction chip clearance
• Non-centercutting — requires a pre-drilled entry point for plunge operations
• Consistent 3/4 inch shank and 3/4 inch cutting diameter for direct drop-in to standard 3/4 inch toolholders

Compatibility

Designed as a direct-fit replacement or stock end mill for standard 3/4 inch end mill holders, collet chucks, and milling arbors used on vertical machining centers and manual knee mills.

Installation Notes

Installation should be performed by a qualified machinist following shop safety protocols. Power down and lock out the machine spindle before seating or removing the tool from its holder. Ensure the shank is fully seated to the recommended engagement depth in the holder or collet before tightening. Because this is a non-centercutting end mill, do not attempt direct plunge cuts without a pre-drilled pilot hole.
