Abstract

1,062,125. Boring tools. SOC: NATIONALE DES PETROLES D'AQUITAINE. May 28, 1964 [May 28, 1963], No. 22188/64. Heading E1F. A rotary boring tool operating with jets of fluid comprises a head with fluid-distributing passages connected with a central channel and terminating in apertures 1c - 5c, arranged along 'meridians' (i.e. lines radiating from the rotary axis) of equal length so that the surface generated thereby on rotation of the tool covers the tool boring surface. The sum of the radial lengths of the apertures being at least equal to the length of one 'meridian'. The head is divided into zones 1a - 5a each covered with boring members 6 consisting of diamonds, tungsten carbide or cutting blades and separated by grooves 1b - 5b. Preferably there are more aperturese adjacent the rotary axis than towards the periphery of the head. Grooves w, shown connected with apertures 5c, may be provided to increase the supply of fluid to the boring area.
