Abstract: A self-contained, multi-blade package is constructed to be mounted in the blade head assembly of a slurry saw for cutting hard materials such as quartz, silicon, germanium, and the like. The blade package is pre-assembled with connecting rods extending through aligned holes of spacer plates and end caps which extend above and below the blades at either end of the blades. At least one end cap of each pair is drilled with a through hole or holes and counter bored to receive a nut threaded on the connecting rod which projects into the counter bore. The end caps have a thickness on the order of one-half their width dimension resulting in great dimensional stability. This prevents distortion of the blade pack when the nuts are tightened on the connecting rods ensuring parallelism and rigidity of the blade package. The end caps further eliminate the need for clamping blocks normally used in the blade head assembly of slurry saws thereby permitting more blades to be incorporated in the blade package.
