  • Patent number: 8678725
    Abstract: A bit retaining system for a rotary tool or device such as a router is disclosed. The bit retaining system may include a collet assembly and a control assembly. The collet assembly may include a spindle, a collet adapted to receive the bit, and a collet nut. The collet assembly may further include a collet gear mounted on the collet nut and/or a spindle gear mounted on the spindle. The control assembly selectively engages the collet assembly to drive the collet nut and/or secure the spindle in a fixed position, preventing its rotation. In operation, a hand tool is utilized to engage the control assembly. This configuration enables a user to capture and release the rotary tool bit using one hand.

  • Publication number: 20140000921
    Abstract: A power tool includes a housing, an output shaft having a tool axis, and a motion sensor that senses motion of the tool housing. A control circuit receives an input signal from the motion sensor, to make a first determination, based on the input signal, whether the tool is being operated in a horizontal mode or a vertical mode. The control circuit makes a second determination, based on the input signal, whether the tool axis is substantially level when the tool is being operated in the horizontal mode or the tool axis is substantially plumb when the tool is being operated in the vertical mode. An indicator receives an output signal from the control circuit that causes the indicator to indicate whether the tool axis is level when being operated in the horizontal mode or plumb when being operated in the vertical mode.

  • Publication number: 20130306341
    Abstract: A power tool having a rotary impact mechanism and a mode change mechanism. The impact mechanism is driven by an output member of a transmission and includes a hammer and an anvil. The mode change mechanism includes a mode collar that is movable between a first position, in which the mode collar directly couples the hammer to the transmission output member to inhibit movement of the hammer relative to the spindle, and a second position in which the mode collar does not inhibit movement of the hammer relative to the spindle.

  • Publication number: 20130021783
    Abstract: A power tool includes a tool body having an output member that drives an accessory. An end effector is coupled for rotation with the output member. A light source is disposed on the end effector. A primary coil assembly is configured on the tool body and mounted concentric to the output member. The primary coil assembly includes a primary coil that is electrically connected to a power source of the power tool. A secondary coil assembly is configured on the end effector and mounted concentric to the output member. The secondary coil assembly includes a secondary coil that is electrically connected to the light source. Current flowing through the primary coil creates a magnetic field that causes current to flow through the secondary winding and power the light source.
