A cast spreading device for spreading the severed wall of a cast comprising a handle having a finger pivoted lever which actuates a longitudinally movable shaft through a barrel. The distal end of the barrel has fixed thereon a bit. The distal end of the shaft passing through the barrel carries a second bit which operates to move away from the bit on the barrel as the shaft is advanced through the barrel. This operation functions to spread the cast apart when the bits are embedded in the cut of the cast.
