Abstract: A cart for carrying a cut-off saw having a saw blade. The cart includes a frame with upper and lower portions, a wheel arm pivotably coupled to the lower portion about a first axis, and a rear wheel assembly coaxial with the first axis and coupled to the frame and the wheel arm. The cart includes a front wheel coupled to an end of the wheel arm opposite the rear wheel assembly, an adjustment lever pivotably coupled to the upper portion about a second axis, and a link having a first end pivotably coupled to the adjustment lever and spaced from the second axis, and a second end pivotably coupled to the wheel arm between the first axis and the front wheel. Pivoting the adjustment lever about the second axis pivots the wheel arm about the first axis to adjust a vertical position of the front wheel relative to the upper portion.

Abstract: A reciprocating saw includes a housing, a motor, a drive mechanism, and a support assembly. The drive mechanism includes a driven gear, a connecting rod, and a spindle. A first end of the connecting rod is moveably coupled to the spindle by a roller pin. Rotary motion of the motor is translated into linear reciprocating motion of the spindle by the driven gear and the connecting rod. The support assembly rotationally supports the roller pin and includes a housing which defines a slot. A first bearing is positioned within the slot at a first end of the roller pin, and a second bearing is positioned within the slot at a second end of the roller pin. At least one of the first end and the second end of the roller pin extends completely though the first bearing and the second bearing, respectively.

Abstract: An angle grinder includes an output shaft defining a rotational axis, a housing from which the output shaft extends, and a flange coupled to the housing and surrounding the output shaft. The angle grinder further includes a first circumferential groove defined between the flange and the housing, a first array of radially outward-extending slots in the flange and in communication with the first circumferential groove, and a keyway defined in the housing. The keyway is positioned inline with a first of the radially outward-extending slots in the first array. The angle grinder further includes a guard with a second array of radially inward-extending projections and a key positionable within the keyway. The radially inward-extending projections are received in the radially outward-extending slots. The key is able to close the first radially outward-extending slot in the first array to prevent removal of the guard from the housing.

Abstract: The present invention provides a grinder including a housing, a drive assembly within the housing including an electric motor having a motor shaft, and an output spindle coupled to the motor shaft for rotatably driving a grinding tool. The grinder further includes a tool-free attachment mechanism for selectively mounting the grinding tool to the output spindle for co-rotation therewith including a flange nut threaded to the output spindle, and a backing flange axially movable along the output spindle between a first position, in which a space exists to position the grinding tool between the flange nut and the backing flange, and a second position, in which the grinding tool is clamped between the backing flange and the flange nut.

Abstract: A drill stand includes a base supportable upon a mounting surface, a mast defining a longitudinal axis and extending upward from the base, a carriage moveably coupled to the mast and configured to support a core drill thereon, a spindle assembly for moveably adjusting the carriage along the mast, a handle assembly for rotating the spindle assembly, and a lock assembly that is operable to secure the carriage in a selected position on the mast. The lock assembly includes a first adjustment dial positioned on a first side of the carriage, a second adjustment dial positioned on a second side of the carriage, and a locking member operably coupled to the first and second adjustment dials to selectively secure the carriage on the mast.

Abstract: A core drill assembly includes a core drill and a stand upon which the core drill is mounted. The stand includes a base supportable upon a mounting surface, a mast defining a longitudinal axis and extending upward from the base, a carriage moveably coupled to the mast and configured to support the core drill thereon, and at least one leg pivotably coupled to the base between a deployed position, in which the leg extends away from the base, and a stowed position, in which the leg is at least partially recessed within the base.

Abstract: A blade clamp is configured for use with a power tool having a reciprocating spindle. The blade clamp includes a cover assembly rotatably coupled to the spindle, and a detent received within a first bore of the spindle. The detent is movable in a radial direction relative to a longitudinal axis of the spindle by engagement with the cover assembly to adjust the blade clamp between a locked configuration and an unlocked configuration. The blade clamp further includes a sleeve in which the detent is slidably received. The sleeve is at least partially positioned within the first bore. A plunger is positioned within a second bore of the spindle. The second bore extends along a longitudinal axis that is parallel with the longitudinal axis of the spindle. The second bore is contiguous with a blade slot of the spindle.
