How does a end mill work?
End Mills are used for making shapes and holes in a workpiece during milling, profiling, contouring, slotting, counterboring, drilling and reaming applications. They are designed with cutting teeth on the face and edge of the body and can be used to cut a variety of materials in several directions.
What materials can be used for end mills?
Most end mills are manufactured from either cobalt steel alloys – referred to as HSS (High Speed Steel), or from tungsten carbide. The choice of material of your selected end mill will depend on the hardness of your workpiece and the maximum spindle speed of your machine.23 sept 2019
What is the most common type of material used in end mill cutters?
They are usually made from high speed steel or cemented carbide, and have one or more flutes. They are the most common tool used in a vertical mill.
