Abstract: A power tool for forming threads includes a tool housing with a motor housing portion having a first handle, a battery receptacle configured to receive a battery, a motor housing portion with a motor, a transmission housing portion with a transmission, and an operating head portion arranged along a tool axis. A cutting head is at least partially received in the operating head portion and rotates about a rotational axis transverse to the tool axis to form threads in a workpiece. A second handle is coupled to the operating head or the tool housing adjacent the operating head. When power is applied to the motor, the motor rotates and the transmission transmits torque from the motor to rotate the cutting head. A center of gravity of the power tool is positioned at a portion of the tool housing substantially aligned with the second handle.

Abstract: A power tool includes a housing, a motor disposed in the housing, an output spindle configured to be driven by the motor, an input switch, and a controller configured to control power being delivered to the motor. The controller is operable in one of: (a) a normal mode where the controller causes continuous electric power to be delivered to the motor during actuation of the input switch in a first range of positions; and (b) a feathering mode where the controller causes discontinuous electric power to be delivered to the motor during actuation of the input switch in a second range of positions that is different from the first range of positions motor to simulate feathering the input switch.

Abstract: A modification system for the modification of elongated pieces of stock may include a powered tool for modifying, or altering the piece of elongated stock, and a support device for supporting a position of the elongated stock relative to the powered tool. An arrangement of the components of the powered tool may provide for ergonomic balance of the powered tool. The support device may include a clamping device that clamps, or holds the elongated stock, and an adjustment device that adjusts a position of the clamping device based on a size of the elongated stock. The support device may include a latching device that maintains the position of the clamping device relative to the stock. A reaction arm may inhibit rotation of the tool relative to the stock during operation. A biasing device may provide for application of an axial biasing force on the stock, to initiate operation.

Abstract: The cordless power cutter that is lightweight and weight-balanced between a power section housing a battery pack as a power source and a cutting section including a motor in a belt-free drive system and rotatable disk blade. The weight balancing of the cordless power cutter allows the tool to remain parallel to a horizontal surface, such as the ground, without tilting, when the operator lifts and holds the tool by only a gripping or transverse portion of the lifting handle. The motor has a motor axis that is not perpendicular to the disk axis and that is rearward of the disk axis to provide a depth of cut. The weight-balance and motor positioning allows the cordless power cutter to achieve ease of handling and operation.
