Value Collection 723-4320 Square End Mill 5/64 in Cobalt

Product Description

The VALUE COLLECTION 723-4320 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, this tool offers improved heat and wear resistance compared to standard M2 HSS end mills, making it well-suited for harder workpiece materials. The double-end design delivers two usable cutting ends, extending tool life between replacements. With a 5/64 inch (0.0781 inch) cutting diameter and four spiral flutes at a 30-degree helix angle, it generates a smooth finish while efficiently evacuating chips in tight cavities and small-feature work.

This end mill is intended for use in manual mills, CNC machining centers, and toolroom applications where small-diameter precision cutting is required. The regular-length configuration with a 3/16 inch shank diameter accommodates standard collet systems. Its center-cutting geometry allows plunge entry as well as conventional peripheral milling. Machinists working on die, mold, fixture, and prototype components will find this tool appropriate for fine detail work in steel alloys and similar materials.

Key Features

• M42 cobalt HSS construction for improved heat resistance over standard HSS
• Double-end design provides two cutting ends per tool
• Center-cutting capable, allowing direct plunge entry
• 4-flute, right-hand spiral at 30-degree helix angle for smooth chip evacuation
• Bright/uncoated finish suitable for use with or without cutting fluids
• Right-hand cutting direction compatible with standard spindle rotation

Compatibility

Designed as a standard fractional-inch shank end mill compatible with 3/16 inch collets and end mill holders used in vertical milling machines and CNC machining centers.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer's guidelines. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Seat the shank fully into the collet or holder and torque the retention mechanism per the holder manufacturer's specification. Verify runout with a dial indicator before beginning a cut on critical features.
