ABOUT THIS CATEGORY
Square end mills, also called square-nose end mills or flat end mills, are general purpose mills that generate a flat surface with 90-degree corners in a workpiece. Unlike conventional drill bits, end mills have cutting teeth at the sides and tip of the mill. They can be used used in the roughing and finishing stages but they can also be used for plunging, grooving, side milling, face milling, and counterboring. Flat end mills are usually made from carbide steel or other high-speed steel composition. They are available in various flute counts and sizes.
