Abstract

501,331. Depth-stops for drills. GATES, C. S., and ALLEN MANUFACTURING CO. Aug. 19, 1938, No. 24476. [Class 83 (iii)] In a drilling &c. depthstop of the kind having a body with an opening therethrough to receive the tool and by which it is detachably secured to the tool, one or more lugs project axially from the body and are rounded at their lower ends. The stop consists of a collar 7 attachable to a counterboring drill 5 by means of a screw 11 and having lugs 8 projecting from its lower face 10.
