Value Collection 723-3750 Ball End Mill 5/8 in 4 Flute Cobalt

Product Description

The VALUE COLLECTION 723-3750 is a single-end cobalt ball end mill designed for milling contoured surfaces, slots, and complex 3D profiles in a wide range of workpiece materials. Built from M42 cobalt high-speed steel, it offers greater heat and wear resistance than standard M2 HSS tooling, making it well-suited for harder alloys and demanding cutting conditions. The ball nose geometry produces a smooth radius cut ideal for finishing passes and die work. At 5/8 inch diameter with a 1-5/8 inch length of cut and 4 right-hand spiral flutes, this mill balances chip evacuation with rigidity across a range of depths.

This end mill is used in vertical machining centers, knee mills, and manual milling machines for profiling, contouring, and cavity work in ferrous and non-ferrous metals, plastics, and composites. The bright uncoated finish makes it a straightforward general-purpose choice where re-sharpening or lower tooling cost is prioritized. The 5/8 inch shank diameter provides a secure grip in standard end mill holders and collet chucks. This tool is typically installed and run by machinists in job shop, toolroom, and production environments.

Key Features

• M42 cobalt construction for improved heat resistance over standard HSS
• Ball nose geometry for 3D contouring and radius profiling
• 4 right-hand spiral flutes for efficient chip evacuation and smooth finish
• Bright/uncoated finish compatible with standard cutting fluids and coolants
• Single-end design with 5/8 inch shank for use in standard end mill holders
• 3-3/4 inch overall length providing adequate reach for most cavity and slot applications

Compatibility

Designed as a general-purpose ball end mill for use in standard 5/8 inch end mill holders, collet chucks, and milling machine spindles accepting right-hand cutting tools.

Installation Notes

Installation should be performed by a qualified machinist following shop safety procedures. Secure the shank fully into the holder to the recommended engagement depth and verify runout before cutting. Always confirm spindle speed and feed rate are appropriate for the workpiece material and tool diameter before starting the cut. Inspect the cutting edges for damage before each use and replace or resharpen the tool if chipping or wear is evident.
