Value Collection 723-5705 Roughing End Mill 1/4 in Cobalt

Product Description

The VALUE COLLECTION 723-5705 is a single-end cobalt roughing end mill designed for aggressive material removal in milling operations. Built from M42 cobalt high-speed steel, this 3-flute tool measures 0.25 inches in diameter with a 5/16-inch length of cut and a 2-1/8-inch overall length. The bright, uncoated finish suits applications where coating is not required or where re-sharpening is anticipated. A 3/8-inch shank diameter provides solid tool holding in standard end mill holders and collet chucks. Machinists and tool-and-die professionals use this style of end mill when roughing passes demand chip clearance and cutting efficiency over fine surface finish.

This end mill is suited for roughing operations on ferrous and non-ferrous metals where a standard center-cutting tool is not required. The right-hand cutting and right-hand flute direction make it compatible with conventional CNC machining centers and manual knee mills. The 3-flute geometry balances chip evacuation with core strength, making it a practical choice for slotting, peripheral milling, and profiling on materials within the M42 cobalt speed-and-feed range. Single-end configuration means the tool is replaced rather than flipped when the cutting end wears.

Key Features

• M42 cobalt construction for improved wear resistance and heat tolerance versus standard M2 HSS
• 3-flute roughing geometry promotes efficient chip evacuation during aggressive cuts
• Bright uncoated finish — compatible with re-sharpening and oil-based cutting fluids
• 3/8-inch shank diameter fits standard collet chucks and end mill holders
• Right-hand cut, right-hand flute — standard orientation for most vertical machining setups
• Non-center-cutting design — requires a pre-drilled or pre-bored entry point for plunge applications

Compatibility

Designed as an OEM-style replacement or standard roughing end mill for use in conventional and CNC vertical milling setups accepting a 3/8-inch shank end mill holder or collet.

Installation Notes

Installation should be performed by a qualified machinist following shop safety protocols. Ensure the spindle is fully powered down and locked out before changing tooling. Seat the shank fully in the collet or holder to the recommended depth and torque the retention hardware per the tool holder manufacturer specifications. Confirm cutting direction matches spindle rotation before initiating a cut.
