A percussion tool includes a housing, a percussion mechanism including a striker supported for reciprocation in the housing along a first axis, and an anti-vibration system for attenuating vibration in a direction of the first axis. The anti-vibration system includes a linkage coupling the percussion mechanism to the housing. The linkage permits relative movement between the housing and the percussion mechanism along the first axis. The anti-vibration system also includes a counterweight supported by the percussion mechanism for relative movement therewith along a second axis that is parallel with the first axis. The counterweight reciprocates out of phase with the striker to attenuate vibration in the direction of the first axis.

The present invention provides, in one aspect, a router including a motor unit and a base configured to selectively receive the motor unit to support the router on a work piece surface. The motor unit includes a motor and a spindle configured to output a torque supplied by the motor. The base includes an input shaft configured to selectively couple to the spindle, an output shaft laterally offset from the input shaft, and a belt. The input shaft includes a first pulley and the output shaft includes a second pulley and a tool holder. The belt wraps around the first and second pulleys to rotationally couple the input shaft to the output shaft. When the motor unit is received into the base, the spindle couples to the input shaft.

Offset base for router

A handheld power tool includes a housing, a tool receptacle disposed on a first end of the housing and configured to receive a tool accessory, a motor positioned within the housing and operatively coupled to the tool receptacle to drive the tool accessory, and a dust collection assembly integrated within the housing. The dust collection assembly includes a fan disposed within the housing and operatively coupled to the motor. The fan is configured to generate a suction airflow due to rotation of the motor, and a dust container removably coupled to the housing of the power tool. The dust container is configured to collect dust and other debris generated by the tool accessory during operation of the handheld power tool.

Integrated dust extractor and power tool

A portable welder that includes a portable housing, a ground clamp, an electrode holder, a user interface, and a battery pack interface. The ground clamp is connected to the portable housing through a ground cable and is configured to be connected to a metal workpiece. The electrode holder is connected to the portable housing through an electrode cable. The electrode holder includes a mount connected to the electrode cable and a user input. The mount is configured to hold a consumable electrode. The user input is configured to activate the portable welder. The user interface located on the housing. The battery pack interface is configured to receive a removable and rechargeable battery pack.

Portable battery pack-powered welder

A potting boat adapted to receive a printed circuit board is described. The boning boat includes a base plate and a plurality of sidewalls projecting from the base plate, a plurality of cooling fins, a recessed portion, and an arm. The plurality of cooling fins are formed on one of the sidewalls. The cooling fins extend laterally outward from the one of the sidewalls. The recessed portion is in a first sidewall of the plurality of sidewalls, and extends laterally inward. The arm has a first end fixed to the sidewall and an opposite, second end not connected with the first sidewall. The arm at least partially overlays the recessed portion to define a void within which electrical wires connected to the printed circuit board are retained proximate the first sidewall.

A rotary hammer includes a motor and a spindle coupled to the motor for receiving torque from the motor. The spindle has an adjustable rotation speed. A reciprocation mechanism is operable to create a variable pressure air spring within the spindle and includes a piston configured to reciprocate within the spindle in response to receiving torque from the motor. The piston has an adjustable reciprocation frequency. A striker is selectively reciprocable within the spindle in response to reciprocation of the piston. A first transmission is transfers torque from the motor to the spindle and a second transmission is transfers torque from the motor to the reciprocation mechanism. The reciprocation frequency of the piston is adjustable independent of the rotation speed of the spindle. The rotation speed of the spindle is adjustable independent of the reciprocation frequency of the piston. At least one of the transmissions is a multi-speed transmission.

Rotary power tool

A handheld power tool including a housing, a tool receptacle disposed on a first end of the housing and configured to receive a tool accessory, and a motor positioned within the housing and operatively coupled to the tool receptacle to drive the tool accessory. A dust container is selectively coupled to the housing. A dust tube is coupled to the first end of the housing and in fluid communication with the dust container, wherein the dust tube is movable between an extended position and a retracted position. A fan is positioned within the housing and is operable to generate a suction air flow path through the dust tube and into the dust container, wherein the fan rotatably driven by the motor.

A method for reducing vibrations in a percussion tool includes activating, using an electronic controller of the percussion tool, the motor of the percussion tool, determining, using the electronic controller, that the percussion tool is in a loaded condition, and operating, using the electronic controller, the motor in accordance with a predetermined profile in response to determining that the percussion tool is in the loaded condition. The method also includes determining, using the electronic controller, that the percussion tool is in a no-load condition and operating, using the electronic controller, the motor with reduced speed in response to determining that the percussion tool is in the no-load condition.

A rotary hammer includes a housing, a first motor supported by the housing and defining a first motor axis, a second motor supported by the housing and defining a second motor axis that is coaxial with the first motor axis, and a spindle coupled to the first motor for receiving torque from the first motor, causing the spindle to rotate.
