  • Publication number: 20250236009
    Abstract: A drill bit cooling system is provided. After drilling use, the drill tip of a drill bit reaches higher temperatures than a shank or flute of the drill bit. Compartments are provided that are sized in length and width (diameter) to accommodate the drill bit and a cover or back plate with an increased melting temperature facilitates the storage of hot drill tip. By using different components to construct the drill bit holder, a lightweight and versatile cooling system permits the drill bit to be rapidly interchanged on a power tool or drill, without melting through the storage device. This helps the operator interchange drill bits while working on a workpiece without waiting for each drill bit to cool prior to storing and replacing the drill bit.

  • Patent number: 10710257
    Abstract: A power tool includes a housing having a first portion defining a forward end of the housing, a second portion defining a rearward end of the housing, an upper surface extending rearwardly from the forward end, and a lower surface extending forwardly from the rearward end. The power tool also includes a motor positioned within the housing, a drive mechanism coupled to the motor and positioned within the housing, an output element coupled to the drive mechanism at the forward end of the housing, a battery pack supported at the rearward end of the housing and electrically coupled to the motor, and an actuator operable to selectively power the motor to drive the drive mechanism and the output element. The actuator is supported by the housing forward of and above the battery pack.

  • Patent number: 9764486
    Abstract: A power tool includes a housing, a motor positioned within the housing, a drive mechanism coupled to the motor and positioned within the housing, and a shear head rotatably mounted to the housing and coupled to the drive mechanism. The power tool also includes a manually-operable actuator supported by the housing. The actuator is movable between a first position, in which the shear head is held stationary relative to the housing, and a second position, in which the shear head is rotatable relative to the housing.

  • Patent number: 9511923
    Abstract: A powered dispensing tool includes a housing, a motor positioned within the housing, a rack coupled to the motor for powered translation in at least one of a forward direction and a reverse direction, and a transmission selectively coupling the motor and the rack. The transmission includes an input ring rotatable in response to rotation of the motor in a first direction corresponding with powered translation of the rack in the forward direction, a first clutch member engaged with the rack through an intermediate gear, and a second clutch member that receives torque from the input ring and that is movable in response to rotation of the motor in the first direction toward a first position engaging the first clutch member. The second clutch member is also movable in response to rotation of the motor in an opposite, second direction toward a second position disengaged from the first clutch member.

  • Patent number: 9316352
    Abstract: An electrical tool includes a trigger lock assembly having a trigger lock member, a detent assembly, and a return spring. The trigger lock member is movable relative to a trigger between a neutral position, in which the trigger is movable between an off position and an on position, a lock-off position, in which the trigger is prevented from moving from the off position, and a lock-on position, in which the trigger is maintained in the on position. The detent assembly is operable to releaseably retain the trigger lock member in each position and includes a recess associated with each position. The detent assembly also includes a projection selectively engageable in one of the recesses to releasably retain the trigger lock member in the associated position, and a biasing member biasing the projection into engagement. The return spring is operable to bias the trigger lock member toward the neutral position.
