Value Collection 723-1405 Ball End Mill 2 Flute Cobalt

Product Description

The VALUE COLLECTION 723-1405 is a cobalt ball end mill designed for milling contoured surfaces, slots, and complex 3D profiles on CNC and manual milling machines. Built from M42 cobalt high-speed steel, this single-end tool offers improved heat and wear resistance compared to standard M2 HSS, making it well suited for harder workpiece materials and interrupted cuts. With a 0.25 inch cutting diameter and a 0.625 inch length of cut, the 723-1405 handles light-to-medium material removal in a compact geometry. The bright, uncoated finish allows straightforward resharpening without stripping a coating layer.

This ball end mill is a standard fitment for job shops, tool rooms, and production environments running ferrous and non-ferrous materials where a cobalt grade is specified. The 0.375 inch shank diameter fits ER collet chucks and end mill holders common to most knee mills and machining centers. The 2.4375 inch overall length keeps the tool short enough to maintain rigidity in typical setups. Right-hand cut and right-hand spiral fluting are compatible with conventional CNC spindle rotation.

Key Features

• M42 cobalt HSS construction for improved heat resistance over standard HSS grades
• Ball-nose geometry for 3D contouring, profiling, and radius-bottom slot work
• Bright, uncoated finish — resharpenable without coating removal
• 2-flute spiral design balances chip evacuation and cutting edge strength
• Right-hand cut and right-hand flute direction compatible with standard CNC spindle rotation
• Single-end configuration — standard length for rigid setups

Compatibility

Designed as a standard 0.375 inch shank ball end mill compatible with ER collet chucks, end mill holders, and other 3/8 inch bore toolholding systems used on vertical milling machines and CNC machining centers.

Installation Notes

Installation and tool changes must be performed with the machine spindle fully stopped and the control in a safe, locked-out state per shop lockout/tagout procedures. Seat the shank fully into the collet or holder and torque the retention nut to the toolholder specification before beginning any cut. Inspect the cutting edges for chipping before each use. Do not exceed the tool manufacturer's recommended speeds and feeds for the workpiece material and depth of cut being run.
