Value Collection 723-4330 Square End Mill 5/32 in Cobalt

Product Description

The VALUE COLLECTION 723-4330 is a cobalt square end mill designed for milling, slotting, and profiling operations on ferrous and non-ferrous materials. Built from M42 cobalt high-speed steel, it handles heat and wear better than standard HSS tooling, making it a practical choice for harder workpiece materials and higher-feed applications. The double-end configuration provides two usable cutting ends, extending tool life before replacement is needed. Key geometry includes a 5/32-inch cutting diameter, a 7/16-inch length of cut, and a 30-degree helix angle with four spiral flutes for efficient chip evacuation. It is center-cutting and right-hand cutting with a right-hand flute direction.

This end mill is suited for manual mill and CNC machining center applications where small-diameter, close-tolerance work is required. The 3/16-inch shank diameter fits standard collets and end mill holders used in typical vertical knee mills and CNC machining centers. The bright, uncoated finish makes it a general-purpose option across a range of shop environments. Machinists and tool-and-die professionals working in job shop, maintenance, and production settings will find this a reliable small-diameter cutter for detail work and secondary operations.

Key Features

• M42 cobalt construction for improved heat resistance over standard HSS
• Double-end design doubles usable cutting life per tool
• Four spiral flutes with 30-degree helix angle for efficient chip removal
• Center-cutting geometry allows plunge entry into workpiece
• Bright/uncoated finish suitable for general-purpose milling applications
• Right-hand cut and right-hand flute direction, standard configuration

Compatibility

Designed as an OEM-style replacement or standard tooling option for use in collet-style end mill holders and standard ER collet chucks accepting a 3/16-inch shank diameter.

Installation Notes

Installation is performed by qualified machinists following standard machine tool safety procedures. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Verify collet and holder are clean and free of chips before seating the shank. Confirm runout with a dial indicator after clamping before beginning a cut.
