摘要： A multi-part conduit bender handle preferably includes at least a lower tube and an upper tube. The lower tube preferably has an outer diameter, which allows a ¾ male national pipe tap (NPT) to be formed on opposing ends thereof. One end of the lower tube is threaded into a female ¾ NPT in a conduit bender head. An inner diameter of the upper tube is preferably sized to receive a ¾ EMT conduit. A modified ¾ female NPT is formed in one end of the upper tube and an opposing end is left open for insertion of the ¾ EMT conduit. The first modification difference is the inner diameter of the upper tube is preferably enlarged to about 1.00 inch on one end and the second modification difference is the depth of the modified ¾ NPT threads is preferably increased to about 0.85 inches.

摘要： A tool, such as a conduit bender, that includes a gear assembly for providing a mechanical advantage when bending a workpiece conduit. The gear assembly comprises a pinion gear rotatably coupled to a handle, the handle including a pin that can be selectively engaged with the pinion gear. The conduit bender also includes a shoe with teeth that protrude radially inward from a curved outer portion. When the conduit bender is in use, the teeth of the pinion gear engage with the teeth of the shoe.

摘要： A tube bending tool (1) comprising support surfaces (2, 2′, 2″), between said surfaces a tube (3), to be bent, is placed. A pressure exerting unit (6) with an extension (8) displaceable towards the tube (3), where a convex, bent bearing surface (10) is provided in order to press against the tube (3) when said extension (8) delivers a force from the pressure exerting unit (6). The front portion (9) comprises elongated elements (12, 12′). The outer ends of the elongated elements (12, 12′) comprise displaceable and movable support elements which press on the outer surface of the tube. The inner ends (13, 13′) of the elongated elements are cross-laid and movable, so that they during bending, press in a direction towards the center of the bending radius of the tube (3), at the same time as different radii of the bend (5) can be provided on different places. There is also an optional limiting means for bends over 90 degrees.

摘要： A powered bending tool comprises a portable drive housing including a handle and having a powered drive gear. A bracket is secured to the housing defining a pivot connection spaced from the drive gear. A driven gear is pivotally connected to the bracket at the pivot connection and operatively engages the drive gear. A center guide is connected to the bracket at the pivot connection. A support is operatively connected to the bracket at one side of and spaced from the pivot connection. An arm has a near end pivotally connected to the bracket at the pivot connection and a distal end having an arm guide at another side of the pivot connection relative to the guide. The arm is selectively engeagable by the driven gear to be rotated therewith. In use, a rod is positioned below the center guide and above the arm guide and a support, and the drive gear drives the driven gear to pivot the arm so that the arm guide deforms the rod as it engages the center guide at a bend point.
