Transverse axis rotary hammer

A rotary hammer configured to impart impacts to a tool bit, the rotary hammer comprising:

• a housing including a first end having a handle and a second end having a chuck, the handle defining a handle axis;
• a motor disposed within the housing;
• a spindle disposed within the housing and rotatable by the motor, the spindle defining a spindle axis that is transverse to the handle axis;
• a transmission configured to transfer torque from the motor to the spindle;
• an impact mechanism including:
• a piston at least partially received within the spindle for reciprocation therein, and a striker received within the spindle and configured to impart an impact to the tool bit in response to reciprocation of the piston;
• and
• an oscillation mechanism including a wobble assembly coupled between the transmission and the impact mechanism to convert rotational motion of the motor into reciprocating linear motion that moves the piston, the oscillation mechanism coupled to a peripheral side surface of the piston.

A rotary hammer configured to impart impacts to a tool bit, the rotary hammer comprising:

• a housing including a first end having a handle and a second end configured to receive the tool bit, the housing extending along a first direction between the first end and the second end and the handle defining a handle axis that is substantially parallel to the first direction;
• an output assembly disposed in the housing at the second end, the output assembly including:
• a spindle configured to rotate the tool bit about a spindle axis that is substantially perpendicular to the first direction;
• an impact mechanism including a piston at least partially received within the spindle for reciprocation therein,
• an oscillation mechanism coupled at an outer surface between a first end and a second end of the piston and is configured to reciprocate the piston, the oscillation mechanism including a wobble assembly having a wobble bearing,
• a striker received within the spindle for reciprocation in response to reciprocation of the piston;
• and
• a transmission configured to transmit an input torque to the spindle and the impact mechanism;
• and
• a motor positioned between the output assembly and the handle to provide the input torque to the transmission.
