OEM Pencil-Neck Carbide Ball End Mill

A 1/16" carbide ball end mill is used for precision contouring, 3D profiling, and slotting in hardened steels and tool steels. The AlTiN coating extends tool life at high temperatures, making it ideal for mold and die work, aerospace components, and intricate machining where fine detail and surface finish are critical.

This ball end mill has a 1/16" mill diameter, 3/4" length of cut, and 2-1/2" overall length. It is made of carbide with an AlTiN coating, has 2 flutes, and is a pencil-neck design. The manufacturer part number is 251-001121B. These specs suit high-speed machining of ferrous materials.
