Value Collection 723-1644 Square End Mill 9/64 in Cobalt

Product Description

The VALUE COLLECTION 723-1644 is a cobalt double-end square end mill designed for metal removal in demanding machining applications. With a 9/64-inch (0.1406-inch) cutting diameter, a 13/32-inch length of cut, and a 3/16-inch shank diameter, this tool is built for tight-tolerance work on steel, stainless steel, cast iron, and high-temperature alloys. The M42 cobalt construction provides heat and wear resistance beyond standard HSS, making it a reliable choice for harder workpiece materials. It is installed and operated by machinists and tool-and-die professionals on manual mills and CNC machining centers.

This end mill is suited for slotting, profiling, and peripheral milling operations in job shop, production, and maintenance machining environments. The double-end configuration extends tool life by offering a second usable cutting end, reducing per-cut tooling cost. Its bright uncoated finish makes it well matched for general-purpose steel and stainless cutting where a coating is not required or where re-grinding is anticipated. The 30-degree helix angle promotes smooth chip evacuation and reduces cutting forces across the supported workpiece materials: steel, stainless steel, cast iron, and high-temperature alloys.

Key Features

• Double-end design provides two usable cutting ends, extending tool service life
• M42 cobalt material grade offers superior heat resistance over standard HSS
• 30-degree helix angle supports efficient chip evacuation and smooth cutting action
• Centercutting capability allows direct plunge entry into the workpiece
• Right-hand cut and right-hand spiral flute — standard orientation for most milling setups
• Bright uncoated finish suitable for general-purpose use and compatible with re-grinding

Compatibility

Designed for use on steel, stainless steel, cast iron, and high-temperature alloys (ISO material codes P, M, K, S). Fits standard 3/16-inch collets and tool holders on manual and CNC milling machines.

Installation Notes

This tool is installed by machinists using a compatible collet or end mill holder sized for a 3/16-inch shank. Confirm the holder is clean, undamaged, and torqued to the machine manufacturer's specification before use. Never exceed the recommended speed and feed rates for the workpiece material and cutting diameter. Inspect both cutting ends before use and replace the tool if chipping, excessive wear, or runout is detected.
