Value Collection 723-5707 Roughing End Mill 1/4 in Cobalt

Product Description

The VALUE COLLECTION 723-5707 is a single-end cobalt roughing end mill designed for aggressive material removal in milling applications. Built from M42 cobalt high-speed steel, it handles tough ferrous and non-ferrous materials while retaining edge hardness under heat. The 1/4 inch (0.25 inch) cutting diameter pairs with a 3/8 inch shank, a 1-3/8 inch length of cut, and a 3-1/8 inch overall length. Three flutes provide chip clearance and cutting efficiency suited to roughing passes. The bright, uncoated finish makes it a straightforward general-purpose choice for machinists and tool and die professionals working in manual or CNC milling environments.

This end mill is suited for roughing operations on mills where moderate chip loads and controlled depth-of-cut passes are required. The single-end configuration is standard for toolroom and production milling work. The right-hand cutting and right-hand flute direction are the conventional geometry for most vertical milling machine and machining center spindles. It does not feature center-cutting geometry, so it is not intended for direct plunge cuts. Typical applications include slotting, peripheral milling, and step milling of steel, stainless, and similar alloys.

Key Features

• M42 cobalt HSS construction retains hardness at elevated cutting temperatures
• 3-flute geometry balances chip evacuation and cutting edge strength for roughing passes
• 1/4 inch cutting diameter with 3/8 inch shank for standard collet and end mill holder fitment
• Bright/uncoated finish suitable for general-purpose ferrous and non-ferrous milling
• Right-hand cut, right-hand helix — compatible with standard CNC and manual milling spindles
• Non-center-cutting design; requires a pre-drilled or pre-milled entry point for plunge operations

Compatibility

Designed as a standard roughing end mill for use in 3/8 inch collets, end mill holders, or shrink-fit tooling on vertical milling machines and machining centers with right-hand spindle rotation.

Installation Notes

Installation should be performed by a qualified machinist following shop safety procedures. Ensure the spindle is fully stopped and the machine is powered down before inserting or removing the tool from the holder. Secure the shank to the full recommended engagement depth in the holder to prevent pullout under load. Because this tool is not center-cutting, do not use it for direct plunge entry into solid material.
