Value Collection 723-1606 Cobalt Square End Mill 5/64 in

Product Description

The VALUE COLLECTION 723-1606 is a cobalt double-end square end mill designed for precision milling in demanding metalworking applications. Built from M42 cobalt high-speed steel, it delivers the heat resistance and edge retention needed when cutting ferrous metals, stainless steel, cast iron, and high-temperature alloys. The 5/64-inch cutting diameter and 1/8-inch length of cut make it well-suited for fine-detail slot milling, profiling, and plunge cuts in tight geometries. Its 30-degree spiral helix angle promotes efficient chip evacuation, reducing heat buildup at the cutting edge during extended tool engagement.

This end mill is intended for use in vertical machining centers, knee mills, and CNC milling machines across job shop, toolroom, and production environments. The stub-length body geometry provides added rigidity at small diameters, reducing deflection during cuts. The double-end configuration effectively doubles usable tool life before the end mill is retired. Right-hand cut and right-hand flute orientation suit standard spindle rotation. It is compatible with primary workpiece materials including steel, stainless steel, cast iron, and high-temperature alloys.

Key Features

• M42 cobalt construction for heat resistance and wear life in ferrous and high-temp alloy machining
• Double-end design doubles usable tool life per end mill
• 30-degree helix angle for efficient chip evacuation and reduced cutting heat
• Centercutting geometry allows direct plunge entry without pre-drilling
• Bright/uncoated finish suitable for use with or without cutting fluid
• Stub-length body reduces deflection at small cutting diameters

Compatibility

Designed for use in standard milling machine collets and tool holders accepting a 3/16-inch shank diameter. Compatible primary workpiece materials include steel, stainless steel, cast iron, and high-temperature alloys per ISO material codes P, M, K, and S.

Installation Notes

Installation is performed by qualified machinists or CNC toolroom personnel. Secure the 3/16-inch shank firmly in a properly sized collet or end mill holder, ensuring adequate shank engagement depth before tightening. Confirm spindle is fully stopped and locked out before any tool change. Do not exceed the rated length of cut when programming axial depth of cut, as overextending the flute contact zone increases deflection risk at this diameter.
