Value Collection 723-1656 Cobalt Square End Mill 3/32 in

Product Description

The VALUE COLLECTION 723-1656 is a cobalt double-end square end mill designed for precision material removal in ferrous and high-temperature alloy applications. Built from M42 cobalt high-speed steel, this tool delivers superior heat resistance compared to standard HSS end mills, making it well suited for harder workpiece materials where tool wear is a concern. The cutter measures 3/32 inches in diameter with a 9/32-inch length of cut, a 3/16-inch shank diameter, and a 2-5/8-inch overall length. The 30-degree helix angle and two-flute spiral configuration promote chip evacuation in tough materials. Both ends are usable, effectively doubling service life between replacements.

This end mill is designed for use in manual mills, CNC machining centers, and knee mills across job shops, maintenance shops, and production environments. Its small diameter and long-series profile make it appropriate for slotting, profiling, and light pocketing in steel, stainless steel, cast iron, and high-temperature alloys. The bright uncoated finish makes it easy to inspect for wear and allows regrinding without coating complications. Machinists and tool-and-die professionals will find this cutter effective in operations requiring tight tolerances in difficult materials at small diameters.

Key Features

• M42 cobalt construction for improved heat resistance and wear life in hard materials
• Double-end design provides two usable cutting ends, extending tool value
• 30-degree right-hand helix promotes efficient chip evacuation during cutting
• Center-cutting capability allows plunge entry as well as peripheral cutting
• Bright uncoated finish supports easy inspection and regrindability
• Long-series length type for added reach in confined or deep-feature applications

Compatibility

Suitable for cutting steel, stainless steel, cast iron, and high-temperature alloys. Compatible with any machine tool spindle accepting a 3/16-inch straight shank, including standard collet chucks and end mill holders on manual and CNC milling machines.

Installation Notes

Installation should be performed by a qualified machinist following shop-standard toolholding procedures. Secure the 3/16-inch shank firmly in a properly sized collet or end mill holder, ensuring adequate shank engagement to prevent pullout. Power down and lock out the machine spindle before loading or changing tooling. Verify runout with a dial indicator before beginning a production cut, particularly when working at this small diameter where deflection and runout have an outsized effect on tool life and part accuracy.
