Abstract

An improved impact tool of the nonrecoil type is provided, to include a molded thermoplastic jacket encasing a hollow core canister having a flowable filler material such as small steel pellets or the like disposed therein and adapted to shift about within the canister for absorbing and dissipating impact shock forces. The hollow canister, which may be lightweight in construction, is partially filled with a selected quantity of the flowable filler material and the residual canister volume is occupied by at least one pulverable slug prior to placement of the canister into a mold for formation of the jacket thereon under heat and pressure. The pulverable slug has sufficient structural integrity to withstand molding temperatures and pressures, so that the slug and filler material cooperatively define a rigid structural backstop to prevent deformation of the hollow canister during the jacket molding step. Subsequently, upon initial use of the impact tool, impact forces cause the filler material to pulverize the slug for disbursement thereof as a powder into voids throughout the filler material, whereupon the filler material is permitted to shift about within the hollow canister to absorb and dissipate impact shock forces.
