Value Collection 723-1640 Square End Mill 7/64 in Cobalt

Product Description

The VALUE COLLECTION 723-1640 is a cobalt square end mill designed for material removal in ferrous and high-temperature alloy applications. Built from M42 cobalt high-speed steel, it delivers heat resistance and edge retention that standard HSS tooling cannot match at elevated cutting speeds. The double-end design provides two usable cutting ends, extending tool life per unit. With a 7/64 inch cutting diameter, a 21/64 inch length of cut, and a 30-degree helix angle, it is suited for slotting, profiling, and peripheral milling in tight-tolerance work. Machinists in job shops, tool rooms, and production environments use this style of end mill for everyday steel and stainless steel operations.

This end mill is appropriate for milling steel, stainless steel, cast iron, and high-temperature alloys. The 3/16 inch shank diameter fits standard collet chucks and end mill holders on manual knee mills, CNC machining centers, and drill presses equipped for light milling. The spiral flute geometry evacuates chips efficiently in conventional and climb milling passes. The centercutting capability allows plunge entry directly into the workpiece without a pre-drilled hole.

Key Features

• M42 cobalt construction for superior heat and wear resistance versus standard HSS
• Double-end design delivers two cutting ends per tool
• 30-degree helix angle promotes smooth chip evacuation and reduced cutting force
• Centercutting geometry allows direct plunge milling
• Bright/uncoated finish compatible with a wide range of cutting fluids and lubricants
• Right-hand cut, right-hand spiral flute configuration for standard milling setups

Compatibility

Designed for use in standard 3/16 inch collet chucks and end mill holders. Primary workpiece materials include steel, stainless steel, cast iron, and high-temperature alloys (ISO material codes P, M, K, S).

Installation Notes

Installation should be performed by a qualified machinist following shop safety protocols. Ensure the machine spindle is fully stopped and locked out before changing tooling. Secure the shank to the full recommended collet or holder engagement depth to prevent pullout under cutting loads. Verify runout with a dial indicator before committing to a finish pass, and apply appropriate cutting fluid for the workpiece material.
