Value Collection 723-3760 Ball End Mill 3/4 in 4 Flute Cobalt

Product Description

The VALUE COLLECTION 723-3760 is a cobalt ball end mill designed for milling contoured surfaces, slots, and three-dimensional profiles in ferrous and non-ferrous materials. Built from M42 cobalt high-speed steel, this single-end tool delivers better heat and wear resistance than standard HSS, making it a practical choice for tougher workpiece materials and higher cutting speeds. The 3/4 inch diameter ball nose geometry generates a full-radius profile at the tip, which is essential for finishing curved surfaces and complex geometries. Four right-hand spiral flutes provide efficient chip evacuation and a stable cutting action. This tool is used by machinists and tool-and-die professionals operating manual or CNC milling equipment.

The 723-3760 is suited for general-purpose machining operations including contouring, profiling, and pocket milling where a ball nose profile is required. With a 1-5/8 inch length of cut and 3-7/8 inch overall length, this mill fits standard toolholding setups without extended-reach adapters. The 3/4 inch shank diameter matches common collet and end mill holder sizes found in most vertical machining centers and knee mills. The bright uncoated finish is appropriate for use with cutting fluid in a wide range of shop applications.

Key Features

• M42 cobalt construction for improved heat resistance over standard HSS
• Ball nose tip geometry for contoured surface milling and 3D profiling
• 4 right-hand spiral flutes for effective chip removal
• Bright uncoated finish compatible with standard cutting fluids
• Single-end design with 3/4 inch shank for straightforward toolholder fitment
• Right-hand cutting direction for use in conventional milling setups

Compatibility

Designed for use in standard 3/4 inch end mill holders, collet chucks, or Weldon-style holders on vertical machining centers and manual knee mills requiring a ball nose end mill with a 3/4 inch shank diameter.

Installation Notes

Installation should be performed by a qualified machinist following the toolholder manufacturer torque and runout specifications. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the shank to the full recommended engagement depth in the holder to minimize runout and prevent pullout under load. Inspect the cutting edges for chipping or wear before each use and replace the tool if damage is observed.
