Abstract: A clutch bypass for a combination drill has a gearbox connected to a motor and an output spindle. The gearbox includes a ring gear. A clutch mechanism is coupled with the gearbox to selectively transmit torque from the motor to the output spindle. The clutch mechanism includes at least one link member disposed adjacent the ring gear and a capture member disposed adjacent the link member for selectively engaging the link member. The link member has a slot formed on an end thereof. The capture member has a first position in which the capture member is at least partially received in the slot, and a second position in which the capture member does not engage the link member.

Abstract: A clutch bypass for a combination drill has a gearbox connected to a motor and an output spindle. The gearbox includes a ring gear. A washer is mounted adjacent the output spindle and a clutch mechanism is coupled with the gearbox to selectively transmit torque from the motor to the output spindle. The clutch mechanism includes at least one link member disposed between the washer and the ring gear and a blocking member disposed adjacent the washer for selectively engaging the washer. The blocking member has a first position in which the blocking member engages the washer, and a second position in which the blocking member does not engage the washer.

Abstract: An impact rotary tool is provided that is switchable between an impact mode where the tool delivers an impacting torque on an output tool and a drill mode where the driver delivers a smooth output on an output tool. The impact rotary tool includes an impact mechanism and a hammer block that in the impact mode is movable parallel to the axis of the driver shaft and delivers reciprocating blows to rotate an anvil and in the drill mode substantially constantly engages the anvil. The impact mechanism includes a stopper that does not contact the hammer block in the impact mode and engages the hammer block in the drill mode to maintain the substantially constant contact between the hammer block and the anvil.

Abstract: A clutch bypass for a combination drill has a gearbox connected to a motor and an output spindle. The gearbox includes a ring gear. A clutch mechanism is coupled with the gearbox to selectively transmit torque from the motor to the output spindle. The clutch mechanism includes at least one link member disposed adjacent the ring gear and a rotatable mode selector disposed adjacent the link member. The mode selector has at least one opening that can receive a bypass member. The mode selector has a first position in which the bypass member does not abut the link member, and a second position in which the bypass member abuts the link member.

Abstract: A trim router heat sink with a bearing seat and shaft lock that mount to a trim router to act as a heat sink. A shaft extends through the bearing seat and has a shaft lock. The shaft is held on one end by the trim router's motor shaft and on the other end by a bearing. The shaft is connected to a collet so that when the motor of the trim router is operated, the shaft turns the collet. The shaft can be locked to facilitate the installation or removal of a cutting tool in the collet.
