A power tool includes a housing containing a motor, an output member configured to be driven by the motor to perform an operation on a workpiece, and a handle having a first end portion coupled to the housing and a second end portion. A base is coupled to the second end portion of the handle. A light emitting assembly is pivotably coupled to the base. The light emitting assembly is configured to be operable in a first mode to illuminate a workpiece and a second mode to indicate a condition of the power tool responsive to the power tool signaling the condition to the light emitting assembly.

Light emitting assembly for a power tool

A multi-speed, power-driven tool may include a transmission mechanism that transmits power from a motor to an output device. A speed selection mechanism may be coupled to the transmission mechanism, to control a speed reduction through the transmission mechanism, and an output speed of the tool. The transmission mechanism may employ a compound, stepped, planetary gear assembly, to provide for an axially compact arrangement of transmission mechanism components, to reduce an axial length of the tool. The speed selection mechanism may employ a multi-staged grounding device, corresponding to the reduced axial length of the transmission mechanism.

Power tool with multispeed transmission

A power tool chuck includes a body with a central bore extending along an axis and configured to receive a tool bit, a plurality of angled passageways, and a plurality of jaws received in the passageways and moveable between an axially forward and radially inward clamping position and an axially rearward and radially outward retracted position. At least one jaw has a rear end lying in a first plane transverse to the axis. A first key drive member coupled to a tail portion of the body is configured to be engaged by a second key drive member on a power tool output shaft to non-rotationally couple the body to the output shaft. The first key drive has a forward end lying in a second plane transverse to the axis. The second plane is axially forward of the first plane when the jaws are in the retracted position.
