ABSTRACT:
A bit and block are disclosed wherein the bit has a flat bar-like forward working portion and a shank rearwardly of said forward working portion. The shank, when viewed in cross section, has a non-circular shape so that, when placed in a support block having a bore of similar size and shape, the bit will not rotate in the block. An expansible clip is used at the rear end of the bit, behind the shank portion, to hold the bit in the block.
