Abstract

335,489. Rondel, F., and Iochum, G. Jan. 22, 1930. Tools; tool-holders.-In a screw-cutting device, a square plate 8, provided with cutting-edges 9 - - 12 is slidably mounted in a depression in the head of a tool-holder and adjusted' by a set screw 5. The plate has one plane face which lies flush with the holder and can be brought up against the chuck to facilitate adjustment; each of its four cutting-edges is backed off to suit a particular size of thread and it is held in the required position by a nut and bolt. A sawcut 3 gives the holder elasticity during cutting.
