Made from steel. Used in conjunction with a pendant drill, hobby drill or micromotor to cut or grind away, shape or give pattern to a surface (usually metal).

Each burr construction is of a number of teeth/blades (in a given shape) mounted onto a shank (usually 3/32).

The shank fits into the collet/chuck of the drill, and when turned removes the surface being worked upon
