Making a Door Knob – Finishing Steps:
 Coining – a form of precision stamping (the term
comes from the initial use of the manufacturing of
coins process)
 Milling – or grinding.
 Drilling – pretty self-explanatory, but it’s a process
that uses drill bits to cut or enlarge holes.
 Tapping – a process of cutting threads using a tap (a
tool).
 The basic components of a door knob are the knob of
course (or the knob top), the rose, shank, and the
spindle.
