Abstract

There is disclosed a base and block assembly for use with an earthworking bit. The assembly comprises a base 2 and a block 4 engaged in the base. The block has a shank portion and a toolholder portion extending from a first end of the shank and adapted for receiving the earthworking bit 10. The assembly also comprises means 28 for causing the block to preferentially fail when exposed to abnormally high cutting loads. Also disclosed is a method for protecting the base of a base and block assembly when in use with an earthworking bit. The method comprises preferentially weakening the block so as to cause the block to fail when exposed to abnormally high cutting loads and engaging the block with the base. <IMAGE>
