The depth control assembly for attachment at one end to a machine tool and at the other end to a drill plate of a jig having selected guide holes positioned over points to be drilled in a production part. The depth control assembly is a spring-loaded adaptor which spaces the drill a constant distance from the production part, regardless of differences in distance between the face of the drill plate and the production part. Through the use of the depth control assembly, an operator can drill holes of a constant depth in the production part without taking separate measurements and making new depth adjustments at each hole location.
