Abstract: A power tool is provided including a tool housing including a motor housing and a handle portion extending longitudinally from the motor housing; a battery receptacle disposed at an end of the handle portion opposite the motor housing, the battery receptacle being configured to receive a battery pack; and a brushless DC (BLDC) motor including an electronically-commutated stator assembly and a rotor assembly configured to rotate with respect to the stator assembly, the stator assembly comprising a stator lamination stack sized to be received within the motor housing having a circumference of approximately 140 to approximately 190 mm. The motor produces a maximum power output of at least 1600 watts for driving an output shaft at a maximum torque of at least 30 inch-pounds and a maximum speed of at least 8000 rotations-per-minute.

Abstract: A cleaning accessory for a vacuum cleaner comprises a housing having a first air inlet on an underside of the housing and an air outlet and a first airflow path between the first air inlet and the air outlet. The cleaning accessory also comprises at least one cleaning brush having at least one flexible cleaning element projecting outwards from a side of the housing. The cleaning accessory also comprises at least one side air inlet on the side of the housing and a second airflow path between the at least one side inlet and the air outlet. The at least one flexible cleaning element is arranged to engage a surface to be cleaned adjacent to the at least one side air inlet.

Abstract: A concentrator nozzle attachment for a blower device is disclosed that increases the airflow velocity of the blower without sacrificing the field of the jetting air. The concentrator nozzle is formed of an outer ring with a centrally located guide surface and is placed at the exit of an air tube. As the air exits the air tube, it's forced to flow around the guide surface, thus increasing its velocity. The attachment is secured to the end of the air tube and so does not alter the outer diameter through which the air exits. In this way, air velocity is increased without reducing its effectiveness.

Abstract: A motor assembly includes a stator having a stator core, stator windings, and a routing insulator configured to electrically insulate the stator core from the stator windings; a rotor rotatably received within the stator; and a bearing bridge received at least partially within the routing insulator and including a main body forming a center pocket arranged to support a bearing of the rotor shaft. A circuit board is provided including a circuit board, and an overmold structure forming an annular body on a surface of the circuit board arranged to mate with the main body of the bearing bridge to substantially seal the center pocket from ingress of debris particles.

The saw also has a miter detent assembly for selectively engaging and disengaging the detent notch.

Abstract: A fastening tool having a nail stop which positions a nail for driving and is made at least in part of a contact material which can be investment cast and/or hardened. The contact material can resist wear from the action of driving the nail and the movement of a driver blade. The nail stop can be configured to align nails fed from a magazine and can be offset from the longitudinal centerline of the fastening tool. The nail stop can have a head contact length which is 0.5% to 95% of the length of the nail to be driven. The nail stop is used in methods for positioning a nail for driving.
