Abstract
A depth stop attached to a drill for producing precise countersinking in drilled holes. The depth stop produces an accurate and precise countersink in drilled holes by limiting the depth to which a drill bit can drill through a work piece. An audible click occurs for every 7.5 micron change in depth in the preferred embodiment. The depth stop is configured such that attempts to over tighten the lock screw which fixes the depth amount will not damage or deflect the working parts of the device thereby producing accurate and repeatable results.
