A powered threaded rod cutter includes first and second cutting dies, an electric motor, a planetary transmission positioned downstream of the motor, a drivetrain for converting a rotational output of the transmission to a pivoting movement of the first cutting die, and a clutch mechanism for redirecting torque from the motor away from a drivetrain and the first cutting die in response to the first cutting die seizing during a rod-cutting operation. The clutch mechanism includes a ring gear in the planetary transmission, and a spring that rotationally affixes the ring gear below a predetermined threshold of reaction torque through the drivetrain and permits rotation of the ring gear above the threshold.

First and second dies can be coupled to a pair of arms on a threaded rod cutting machine. The first die has a body with a front face, a rear face, a side face extending between the front face and the rear face, and a first threaded recess in the first side face and configured to receive a threaded rod to be cut. Crests and troughs of the first thread are aligned with troughs and crests of the threaded rod when the first die engages the rod. The second die has a body with a front face, a side face extending between the front face and the rear face, and a second threaded recess in the side face and configured to receive the threaded rod. Crests and troughs of the second thread are axially offset from troughs and crests of the threaded rod when the second die engages the rod.

A cutting tool attachment for a power tool is freely rotatable about an end of the power tool. A fence provides a complementary flat surface area for the cutting tool attachment to rest against a surface of the material to be cut. The fence prevents free rotation of the cutting tool attachment while in use. A handle allows a user to guide the attachment along the surface of the material, while also providing leverage to keep the attachment against the material surface close to the attachment, but at a safe position to reduce the chance of injury. A user can rotate the power tool relative to the cutting attachment to achieve a comfortable position or to help turn the attachment and power tool. The power tool is therefore positionable along a 360 arc of movement relative to the attachment while the attachment is positioned along the surface of a material.

A power shear tool includes a housing portion, a motor positioned within the housing portion, and a tool head portion extending from the housing portion and including a blade rotatable relative to the tool head portion. The power shear tool includes a workpiece support member positioned proximate the tool head portion. The workpiece support member includes a top surface and a bottom surface opposite the top surface, side surfaces extending between the top and the bottom surfaces, a first channel defined in the top surface and extending from at least one of the side surfaces, and a second channel defined in the top surface. The second channel intersects the first channel and extends transverse to the first channel.

A portable power tool including, within a housing: an electric motor having a drive shaft, an epicyclic reduction gear having planetary gears meshing with a central gear of the drive shaft of the electric motor, the reduction gear being provided with an output shaft that is rigidly connected to a ball screw of a ball screw/nut mechanism and is coaxial to the ball screw, and a support bearing connecting the output shaft to the housing. The tool includes at least one stabilization bearing axially offset relative to the support bearing. The stabilization bearing connects the output shaft of the epicyclic reduction gear to the housing by at least one intermediate part selected from: the drive shaft of the electric motor, planet-carrier axles of the epicyclic reduction gear, and epicyclic reduction gears of the epicyclic reduction gear. The structure is of use in shears, in particular sheet metal shears.

A rescue tool (10) comprises a drive system which is provided inside a housing and which is configured and suitable for actuating a linear displacement of an implement drive member. The drive system is connected for axial rotation to a rotation shaft of an energizable drive source (22), wherein the rotation shaft of the energizable drive source (22) is coupled for force transmission to an axially rotatable spindle (30). The spindle (30) is coupled rotatably to the housing (15) by means of an axial bearing assembly (25, 26) and the drive body (40) is coupled for force transmission to the spindle (30) and to the implement drive member. The drive body is configured and suitable for converting an axial rotation of the spindle (30) to a linear translation of its own.
