Abstract
1,250,146. Boring earth. G. L. ADCOCK. 26 Feb., 1970 [8 April, 1969], No. 9363/70. Heading E1F. A percussive drill bit comprises tapered button assemblies forced fit in tapered bores 88, which have access apertures 92 connected to their rear ends so that the button assemblies can be pushed from the bores. Each assembly comprises a button 104 of tungsten carbide, mounted in a sleeve 95 having a slit 103 permitting contraction of the sleeve inside bore 88. The bit is secured to an anvil which receives impacts from a piston (34, Figure 1 not shown) in a down-hole motor. The drill string may also be rotated.
