ABSTRACT:
A cutting apparatus includes a fixed holder and an orientable holder. The fixed holder is mounted to a cutting drum, and the orientable holder receives a cutting bit which may either be a forward attack bit or a conical bit. Orientation of the bit is accomplished by alignment of the orientable holder with respect to the fixed holder and by alignment of the bit with respect to the orientable holder. In a preferred embodiment, the fixed holder includes a block and liner, and the liner may assume either of two positions with respect to the block. The orientable holder includes passages and grooves for allowing a spray jet and hose to be received in the orientable holder to spray liquid on the cutting bit. The cutting surface of the bit includes two separate cutting tips, and the bit may be oriented to engage either tip with the material to be cut.
