Abstract

121,911. Brooke, G. F. June 8, 1918. Drills; chucks.-A drill is made from a flat bar of steel V-shaped at one end and ground to provide angular cutting edges 9. The edges at the other end are inclined to form a tapered shank 10 which is secured in a split cone 11 on the end of a screwed rod 12. The cone is tightened by a sleeve 14 under the action of a nut 15. The sleeve may be screwed at one end in lieu of the nut, and be milled or provided with flats.
