Milling inserts are replaceable bits that are used to machine tough some of the toughest materials. Some of the materials that they shape or cut are steel, stainless steel, cast iron, non-ferrous materials, Titanium, hardened steel, and plastic.
These inserts are generally made of carbide, which allows them to be durable at extremely high temperatures and during high-speed applications for tasks such as drilling, hole making, finishing, etc.
Once limited to basic shapes, optimizations by manufacturers now allow for a wide variety of milling insert geometric styles that are referred to as elliptical, frustum and helical. Each shape is specific in size, figure, and tolerance determined by the temperatures, elements, and manufacturing task that are required of it.
