  • Publication number: 20200276650
    Abstract: A chuck for a power tool includes a body extending along a longitudinal axis, a central bore extending along the longitudinal axis and configured to receive a tool bit, a plurality of angled passageways defined in the body, and a plurality of jaws at least received in the passageways and moveable between an axially forward and radially inward clamping position to clamp a tool bit and an axially rearward and radially outward retracted position. At least one jaw has a rear end lying in a first plane transverse to the longitudinal axis. A first key drive member is coupled to a tail portion of the body and configured to be engaged by a second key drive member on an output shaft of a power tool to non-rotationally couple the body to the output shaft. The first key drive member extends axially from a rearward end to a forward end that lies in a second plane transverse to the longitudinal axis. The second plane is axially forward of the first plane when the jaws are in the retracted position.

  • Patent number: 9718180
    Abstract: A power tool includes a motor housing defining a first air chamber with a first air inlet that receives a motor. A handle extending from the motor housing defines a second air chamber with a second air inlet that receives an electronics control module. A third air chamber with an air outlet receives a fan coupled to the motor output shaft. The fan: (a) pulls a first ambient airstream through the first air chamber from the first air inlet and into the third air chamber, bypassing the second air chamber, to cool the motor; (b) pulls a second ambient airstream through the second air chamber from the second air inlet and into the third air chamber, bypassing the first air chamber, to cool the electronics module; and (c) exhausts the first and second airstreams from the third air chamber via the air outlet.

  • Publication number: 20140310964
    Abstract: A portable band saw includes a serviceable/replaceable bumper system for allowing the band saw to be easily repaired if damaged from being dropped. An auxiliary handle is adjustably mounted to the band saw and is releasable from its position if subjected to a large force so as to avoid damage to the handle and tool housing. An adjustable guide shoe includes a toolless adjustment. The front and rear section of the band saw are disposed on opposite sides of a polymeric field case. Compression rods are used to isolate compression forces from the polymeric field case. An electric box assembly including a plastic component box is disposed between the field case and a front section of the band saw. A crash guard is mounted adjacent to the field case and includes a sight guide along an edge thereof and a rear blade guard formed integrally therewith.

  • Patent number: 8348727
    Abstract: The present invention is directed to an airflow generation and particle dispersion arrangement for a power tool (e.g., an angle grinder). The arrangement includes a motor, an airflow generation assembly, and a particle dispersion assembly. The airflow generation assembly includes a fan driven by the motor. When engaged, the driven fan generates an airstream that is drawn through the power tool. The particle dispersion assembly includes a passive fan that is not driven by the motor, but instead is driven by the airstream. In operation, the passive fan generates centrifugal and mechanical forces sufficient to remove particles from intake air passing through the particle dispersion assembly.
