A spindle lock equipped hand-held power tool, such as a grinder or circular saw, includes a housing assembly, a motor including a rotating armature shaft, a spindle carried externally of the housing adapted for selectively affixing and releasing a rotating cutting tool and a drive train which drivingly interconnects the motor armature shaft and spindle for the application of torque to the tool upon electrical energization of the motor. A lock member carried in the housing is selectively displaceable along a fixed axis between a locked position wherein it engages a rotating element of the drive train to prevent rotation of the spindle, and a released position. A spring continuously urges the lock member toward the released position. A manually operable lever selectively displaces the lock member between the released and locked positions.
