ABSTRACT:
A cutting tool assembly of the type including a pilot holder and a cutter blade received in a transverse through slot in the pilot holder. The cutter blade is mounted in the transverse slot in the pilot holder in a manner to allow ready replacement of the pilot blade and in a manner to allow the cutter blade to self-align with respect to the central axis of the pilot holder to minimize the stress loading in the cutter blade and minimize blade breakage. In one embodiment, the cutter blade is mounted in the pilot holder by a cartridge which is received in a threaded bore in the pilot portion of the pilot holder and which includes a spring biased pin projecting upwardly into the transverse slot in the pilot holder. In another embodiment, the cutter blade is mounted in the transverse slot in the pilot holder by a pin and slot connection provided by a slot in the blade and a pin passing through the pilot holder.
