Abstract

1326600 Drilling machines ROBERT BOSCH GmbH 13 Nov 1970 [15 Nov 1969] 54075/70 Heading B3C [Also in Division B4] In a rotary-percussive drill, the tool holder is formed with a tool-receiving aperture which has drive-transmission surfaces which are perpendicular to the direction of application of the torque. As shown, the power transmission in the tool is achieved by providing splined connection between the tool holder and tool member. The splines may extend helically.
