Abstract: A magnetically mountable portable drill assembly includes a magnetic base adapted to be mountable to a working surface, a housing coupled to the magnetic base, a motor coupled to the housing, an arbor coupled to the motor for rotation by the motor, a cutter coupled to the arbor for rotation with the arbor and adapted to cut the working surface or a workpiece supported on the working surface, the magnetic base having a front surface facing the cutter, and an illuminator coupled to the magnetic base to emit light from the front surface of the magnetic base for illuminating an end of the cutter and either one of the working surface and the workpiece.

Abstract: A system for recovering concrete wash product includes a support frame mounted pivotally to a chassis of a transit concrete mixing vehicle, and a container mounted to the frame for arcuate movement with the frame, between a collecting position with the container disposed below a discharge chute of the vehicle, and a dispensing position with the container disposed adjacent an opening of a mixing drum of the vehicle. The container initially is placed in the collecting position to receive concrete wash product from the discharge chute by gravity as the chute is cleaned with water. After cleaning, the frame is pivoted to raise the container to the dispensing position, and a valve is opened to allow the concrete wash product to flow from the container into the mixing drum by gravity. In vehicles equipped with booster axle systems, the booster axle frame supports and positions the container, and also supports and positions the booster wheel/axle assembly.

Abstract: A cutter is for driven engagement with a driving device of an arbor. The cutter includes a shank portion having a central axis and extends along the central axis between a first end and a second end. A cutting portion extends from the first end of the shank portion. The shank portion defines an entry channel extending from the second end for guiding the driving device of the arbor during insertion of the shank portion into the arbor. The shank portion also defines a retaining channel extending from the entry channel for selectively retaining the driving device of the arbor. Each of the entry and retaining channels have a trough portion extending toward the central axis. The trough portions of each of the entry and retaining channels have a common configuration for slideably receiving the driving device.

Abstract: A cutter is for driven engagement with an arbor having one of an extending member and a pair of set screws. The cutter includes a shank portion having a central axis and a cutting portion extending from the shank portion along the central axis. A retaining recess is formed in the shank portion for selectively receiving the extending member of the arbor when the arbor is configured to have the driving device. A pair of flats are each formed in the shank portion for engaging the set screws when the arbor is configured to have the set screws. One of the flats extends in a first plane and the other of the flats extends in a second plane perpendicular to the first plane.
