Value Collection 723-3702 Ball End Mill 3/16in 4 Flute Cobalt

Product Description

The VALUE COLLECTION 723-3702 is a single-end cobalt ball end mill designed for machining contoured surfaces, pockets, and three-dimensional profiles in ferrous and non-ferrous materials. Built from M42 cobalt high-speed steel, this cutter offers greater heat and wear resistance than standard M2 HSS tooling, making it well suited for harder workpiece materials and higher-feed applications. The 3/16-inch cutting diameter pairs with a 1/2-inch length of cut and a four-flute, right-hand spiral geometry that balances chip evacuation with surface finish quality. The bright, uncoated finish is compatible with a wide range of cutting fluids.

This end mill is used in vertical machining centers, knee mills, and CNC milling machines across job shops, tool-and-die operations, and general metalworking environments. The 3/8-inch shank diameter accommodates standard collet chucks and end mill holders commonly found in these setups. The 2-3/8-inch overall length provides sufficient reach for typical pocket and contour work without sacrificing rigidity. It is installed and operated by machinists and CNC programmers working in production and prototype settings.

Key Features

• M42 cobalt HSS construction for improved heat resistance compared to standard HSS tooling
• 4-flute, right-hand spiral geometry balances chip removal with surface finish
• Ball end profile suited for 3D contouring, radius profiling, and pocket machining
• Bright/uncoated finish compatible with oil-based and water-soluble cutting fluids
• Single-end configuration with a 3/8-inch shank for secure clamping in collet and end mill holders
• Right-hand cutting direction matches conventional milling machine spindle rotation

Compatibility

Designed as a standard single-end ball end mill for use in vertical mills and CNC machining centers that accept a 3/8-inch shank collet or end mill holder.

Installation Notes

This cutter is installed and changed by qualified machinists. Power down and lock out the machine spindle before inserting or removing any end mill. Ensure the shank is fully seated and the collet or set-screw holder is torqued to the machine manufacturer's specification before engaging a cut. Inspect the cutting edges for chipping before each use, and never exceed the rated depth of cut or feed rate for the tool diameter and workpiece material combination.
