The tool is either pushed or pulled over the work piece. Each tooth is the broaching tool is successively stepped to the each tooth take a deeper “bite” out of the work piece, than the tooth that proceeded it. Each tooth may have its own function, such as roughing, semi-finishing and finishing teeth, thus usually enabling single pass machining.
