Value Collection 723-8671 Square End Mill 13mm 4 Flute Cobalt

Product Description

The VALUE COLLECTION 723-8671 is a single-end cobalt square end mill designed for milling flat surfaces, shoulders, slots, and profiles in ferrous and non-ferrous metals. Built from M42 cobalt high-speed steel, it offers superior heat and wear resistance compared to standard HSS tooling, making it well-suited for harder workpiece materials and interrupted cuts. The cutter features a 13 mm (0.5118 inch) diameter, a 1-1/4 inch length of cut, and a 30-degree right-hand helix that promotes chip evacuation and reduces cutting forces during operation.

This end mill is intended for use in vertical machining centers, knee mills, and manual milling machines in job shop, maintenance, and general manufacturing environments. Its bright uncoated finish keeps regrinding straightforward, and the 1/2 inch shank diameter fits standard ER and side-lock collet systems. It is appropriate for machinists, toolroom technicians, and maintenance mechanics working with steel, stainless, cast iron, and similar materials.

Key Features

• M42 cobalt HSS construction for improved red hardness and tool life over standard HSS
• 4-flute spiral geometry for smooth surface finish and efficient chip removal
• 30-degree right-hand helix reduces cutting forces and improves chip flow
• Center-cutting design allows plunge entry into workpiece
• Bright/uncoated finish simplifies resharpening and regrinding
• Single-end configuration with regular length for general-purpose milling applications

Compatibility

Designed as a general-purpose replacement or production end mill for milling machines and machining centers accepting a 1/2 inch shank diameter in standard collet or side-lock holders.

Installation Notes

Installation and tool changes should be performed only after the machine spindle has come to a complete stop and power has been isolated. Ensure the shank is fully seated and clamped to the minimum recommended engagement depth in the holder before operation. Inspect the collet or chuck for wear before tightening to maintain runout tolerances. Follow machine manufacturer guidelines and applicable shop safety standards when selecting feeds, speeds, and depth of cut for the workpiece material.
