Abstract
819,998. Drills. MOSSBERC. C. W. May 3, 1957, No. 14197/57. Class 83 (3). A drill comprises an axial coolant &c. bore 13 and a cutting-insert 22, e.g. of tungsten-carbide, secured, as by brazing 24, in a diametral slot across the bore, the insert 22 having a thickness less than the diameter of the bore, which it divides into two coolant nozzles 23, one on each side of the insert. The end cutting edges 25 may be formed with negative rake 37 to break the chips into small particles and facilitate their removal by the coolant. The body of the drill, which may be of smaller diameter than the width of the insert, is formed with the usual clearance 26 behind the cutting edges 25, and also with flats 32 leading into the coolantnozzles, and forming outlets 36.
