Tool having a workpiece-engaging structure that positively positions the tool relative to the workpiece

Abstract

A tool that can be retained in a predetermined position relative to a workpiece and to perform an operation on the workpiece includes a head portion and a tail portion. The head portion includes a leg that is adapted to engage a first portion of a workpiece when the tool is in a predetermined position relative to the workpiece. The tail portion extends from the head portion and includes a support having a recess that is adapted to engage a second portion of the workpiece when the tool is in a predetermined position relative to the workpiece. An operation-performing device is supported on the tail portion and is operable to perform an operation on the workpiece when the tool is in the predetermined position relative to the workpiece.
