Value Collection 723-3775 Ball End Mill 1 in 4 Flute Cobalt

Product Description

The VALUE COLLECTION 723-3775 is a single-end ball end mill designed for contour milling, slotting, and profiling operations on a wide range of workpiece materials. Built from M42 cobalt high-speed steel, it delivers added heat and wear resistance compared to standard HSS tooling, making it well suited for harder ferrous materials and interrupted cuts. The cutter measures 1 inch in diameter with a 2-inch length of cut and a 4.5-inch overall length. Four right-hand spiral flutes with a bright, uncoated finish provide sharp cutting edges and efficient chip evacuation across general-purpose machining applications.

This ball end mill is used in vertical and horizontal milling machines, CNC machining centers, and manual knee mills for 3D profiling, radius milling, and die-and-mold work. The 1-inch shank diameter provides rigid tool holding in standard end mill holders, collet chucks, and shrink-fit holders. It is appropriate for production and job-shop environments where cobalt tooling is preferred over carbide for its toughness and re-grindability.

Key Features

• M42 cobalt HSS construction for improved heat resistance and tool life over standard HSS
• Ball-end geometry suited for contour milling, 3D profiling, and radius work
• 4 right-hand spiral flutes for efficient chip removal and surface finish
• Bright/uncoated finish maintains sharp cutting edges for general-purpose use
• 1-inch shank diameter for rigid clamping in standard tool holders
• Single-end design with right-hand cutting direction

Compatibility

Designed for use in standard milling machines and CNC machining centers accepting a 1-inch shank diameter end mill holder, collet chuck, or equivalent tool holding system.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully stopped and the machine is locked out before changing tooling. Seat the shank to the minimum recommended insertion depth in the tool holder and verify runout before beginning a cut. Follow the machine tool manufacturer guidelines and applicable shop safety procedures when setting speeds and feeds for cobalt end mills.
