Abstract

663,243. Chucks ; drills and cutters. NATIONAL RESEARCH DEVELOPMENT CORPORATION. April 4, 1950 [April 6, 1949], No. 9873/49. Drawings to Specification. Class 83 (iii). The jaws of a drill chuck are arranged and formed so that they provide cutting-means for countersinking or otherwise facing a hole. As described, the ends of the jaws are tapered at about 45 degrees and their edges are backed off so that, in the fully-contracted position, they will countersink a hole already drilled or, if a drill is inserted in the chuck, will enable drilling and countersinking to be carried out in one operation.
