About Cobalt End Mills
Cobalt end mills are a type of cutting tool used for milling operations in industrial and commercial settings. They are specifically designed to cut through harder materials than traditional high-speed steel (HSS) end mills, making them ideal for precision machining and milling applications. Cobalt end mills come in a variety of shapes and sizes, including drill end mills, square end mills, and roughing end mills.
Types of Cobalt End Mills
Cobalt end mills are made from cobalt steel alloy, which is harder than HSS or carbide. This makes them an ideal choice for general purpose machining operations on harder materials such as stainless steel or titanium alloys. Cobalt drill end mills can be used to create specific shapes while cobalt roughing end mills are great for removing large amounts of material quickly.
How Cobalt End Mills are Made
Cobalt end mills are constructed from a combination of cobalt steel alloy, tungsten carbide, and other wear-resistant compounds. The parts of an end mill include the shank, flutes or grooves that form the cutting edge, and the helix angle which determines how quickly it can remove material from the workpiece.
Industries that use Cobalt End Mills
Cobalt end mills are commonly used in automotive manufacturing, aerospace engineering, die making, medical device production, jewelry fabrication and many other industries. Professionals in these fields rely on cobalt tools to get accurate cuts with minimal tool wear when working with hard metals.
