BORE WEAR COMPENSATING BIT HOLDER AND BIT HOLDER BLOCK
A bit assembly includes a base block and a bit holder having a forward body portion and a shank. The bit holder includes a diametrically expanding retainer circumferentially disposed around a shank of the bit holder adapted to maintain the interference contact between the bit holder and the base block as the diameter of a bore of the base block increases from use. The bit assembly also includes a sealing gasket that forms a force fit between a washer disposed about the shank of the bit holder and the base block.
