Abstract
An excavation cutting toolholder retention system. The cutting toolholder retention system includes a cutting toolholder having a flange recess and a holder engagement surface and a support block having a toolholder bore into which the cutting toolholder is inserted and a block pin bore intersecting the toolholder bore, the block pin bore defining a block engagement surface which is inclined downwardly relative to the toolholder bore. The cutting toolholder retention system further includes a pin having a pin shaft, the pin shaft having a pin flange which engages the flange recess so as to limit translational movement of the pin shaft. The pin engages the block engagement surface and the holder engagement surface such that the pin may be moved to draw the cutting toolholder into the toolholder bore.
