Value Collection 723-3660 Cobalt Square End Mill 7/32 in

Product Description

The VALUE COLLECTION 723-3660 is a cobalt square end mill designed for precision milling operations in metalworking and machining applications. Built from M42 cobalt high-speed steel, it delivers increased heat and wear resistance compared to standard HSS tooling, making it well-suited for harder ferrous metals and stainless steels. The stub-length configuration offers added rigidity, reducing deflection during aggressive cuts. With a 7/32-inch cutting diameter, 5/16-inch length of cut, and a 30-degree helix angle, this end mill is optimized for efficient chip evacuation and smooth surface finishes in a variety of milling scenarios.

This end mill is used in vertical and horizontal milling machines, CNC machining centers, and manual knee mills for slot milling, profiling, and peripheral cutting operations. The single-end, right-hand cutting and right-hand flute spiral configuration suits standard spindle setups. The 1/4-inch shank diameter fits standard collets and end mill holders commonly found in both production and job-shop environments. It is installed and operated by machinists, tool and die makers, and skilled CNC operators.

Key Features

• M42 cobalt construction for improved heat resistance and tool life in hard materials
• 3-flute spiral design balances chip clearance and surface finish quality
• 30-degree helix angle promotes efficient chip evacuation and reduced cutting forces
• Stub-length geometry provides rigidity and minimizes deflection
• Center-cutting capability allows direct plunge entry into workpiece material
• Bright/uncoated finish suitable for use with or without cutting fluid

Compatibility

Designed as an OEM-style replacement or direct-use tooling for standard 1/4-inch collets and end mill holders on vertical mills, knee mills, and CNC machining centers requiring a 7/32-inch diameter square end mill.

Installation Notes

This end mill is installed by qualified machinists or CNC operators. Always power down and lock out the spindle before changing tooling. Secure the shank fully within the collet or holder to the recommended engagement depth and verify runout before commencing cuts. Do not exceed the rated length-of-cut range of 0.3000 to 0.5000 inches to avoid tool overload and premature wear.
