Chisel hammer

A power tool adapted to impart axial impacts to a tool bit, the power tool comprising:

• a housing including a motor housing portion and a handle portion extending transversely from the motor housing portion;
• an electric motor supported in the motor housing portion and defining a motor axis;
• a non-rotatable barrel directly coupled to the motor housing portion and extending forwardly of the motor housing portion and defining a barrel axis oriented parallel to the motor axis;
• a tool holder on an end of the barrel opposite the motor housing portion and configured to support the tool bit, the tool holder including a quick-connect mechanism having a sleeve movable between a release position where the tool bit is removable from the tool holder, and a locking position where the tool bit cannot be removed from the tool holder;
• a reciprocation drive assembly coupled to the electric motor and configured to convert torque from the electric motor to reciprocating motion of a piston that is at least partially received within the barrel for reciprocation therein along the barrel axis;
• a striker received within the barrel for reciprocation in response to reciprocation of the piston;
• and
• an anvil at least partially received within the barrel and positioned between the striker and the tool bit, the anvil configured to communicate axial impacts to the tool bit in response to reciprocation of the striker;
• wherein the anvil further includes an open end and a closed end, and wherein the anvil defines an inner bore at the open end configured to at least partially receive a shank of the tool bit.

• a tool holder supported on an end of the barrel opposite the motor housing portion and configured to support the tool bit, the tool holder including a case that partially encloses the barrel at a forward end thereof, wherein the case includes a circumferentially- extending inwardly protruding first rib;
• a reciprocation drive assembly coupled to the electric motor and configured to convert torque from the electric motor to reciprocating motion of a piston that is at least partially received within the barrel for reciprocation therein along the barrel axis;

• and
• an anvil at least partially received within the barrel and positioned between the striker and the tool bit, the anvil configured to communicate axial impacts to the tool bit in response to reciprocation of the striker;
• wherein the anvil includes a circumferentially-extending, outwardly protruding second rib that abuts the first rib of the case to define a forward movable extent of the anvil.
