Abstract
An excavation cutting tool holder retention system. The cutting tool holder retention system includes a cutting tool holder having a holder side surface, a flange recess at least partially enclosed by the holder side surface, and a holder engagement surface together with a support block having a tool holder bore into which the cutting tool holder is inserted and a block pin bore intersecting the tool holder bore, the block pin bore defining a block engagement surface which is inclined downwardly relative to the tool holder bore. The cutting tool holder 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 tool holder into the tool holder bore.
