Demolition hammer with wear plate system having debris channels

A wear plate for a demolition hammer having a housing and a power cell, the wear plate for being interposed between the housing and the power cell, the wear plate comprising a body defining a central longitudinal axis and including:

• a first face, the first face including a first face bottom end, a first face top end in spaced relationship to the first face bottom end along the central longitudinal axis, and a pair of first face lateral edges in spaced relationship to each other along a transverse axis that is perpendicular to the central longitudinal axis;
• a second face, the second face including a second face bottom end, a second face top end in spaced relationship to the second face bottom end along the central longitudinal axis, and a pair of second face lateral edges in spaced relationship to each other along the transverse axis, the first face and the second face being in spaced relationship to each other along a normal axis that is mutually perpendicular to the central longitudinal axis and the transverse axis;
• and
• a pair of sidewalls, the pair of sidewalls respectively extending between the pair of first face lateral edges of the first face and the pair of second face lateral edges of the second face;
• wherein the first face includes a first interface surface, the first interface surface comprising a striated surface defining a series of first face channels disposed in spaced relationship to each other along the transverse axis and extending along the central longitudinal axis;
• wherein the second face includes a second interface surface, the second interface surface defining at least one second face channel extending along the central longitudinal axis;
• and
• wherein each of the pair of sidewalls includes a pair of miter surfaces respectively converging from the first face and the second face to a lateral apex, the pair of sidewalls being symmetrically configured about the central longitudinal axis with respect to each other.
