ABSTRACT:
A drill stop which includes a conically shaped nosepiece facing the drilling surface, the nosepiece having a hole coaxially disposed therein providing a slip fit with the drill diameter. The conically shaped nosepiece retains a coaxially disposed steel spring to soften the shock of drill point breakthrough in drilled material. A bushing sleeve at the end of the steel spring opposite the nosepiece retains the steel spring in position while the end of the bushing sleeve opposite the steel spring-retaining end provides a press fit for one end of a spacer tube, the other end of the spacer tube contacting the drill chuck jaws.
