Abstract

A tool joint for internal drill tubes which are operated with an oscillating movement is secured by a collet which fits into a radial bore through the bell-and-spigot ends of the tubes and is clamped by an expanding cone. The collet has a radial slot through its whole section which is partly taken up by a lug on the expanding cone and partly by an elastic seal.
