Abstract: A pump, such as a vacuum pump, includes at least one housing and a motor and oil reservoir disposed within the housing. The pump housing can include a bottom exterior surface and one or more side and/or front exterior surfaces that extend generally up from the bottom exterior surface. An oil drain port can be positioned at or near the intersection of the bottom exterior surface and the side or front exterior surface. The housing can include an interior bottom surface that defines at least a portion of a drain passageway for the pump and can be fluidicly coupled to the oil reservoir. At least a portion of the interior bottom surface can be angled downward at an acute angle to the horizontal towards the oil drain port to improve the draining and replacement of oil in the pump.

Abstract: A band saw blade can include a blade body having a longitudinally extending back edge along one side and a cutting edge defined by multiple teeth on an opposing side of the blade body. Each tooth can have tip, a rake face disposed along the front side of the tooth, and a relief surface disposed along the opposing rear side of the tooth. A gullet can be disposed between each pair of teeth and can extend from the rake face of one tooth to the relief surface of the next adjacent tooth in the cutting direction. A notch can be defined by the junction of the rake face and the gullet. The rake face can be disposed at a positive angle and with the notch can promote the movement of swarf generated by the tip cutting a work piece into the gullet.

Abstract: A saw blade can include a blade body having a cutting edge defined by multiple teeth. The teeth can be disposed in a repeating pattern including a raker tooth, a first set tooth having a light offset to a right side of the blade body, a second set tooth having a heavy offset to the left side of the blade body, a second raker tooth, a third set tooth having a light offset to the left side, and a fourth set tooth having a heavy offset to the right side of the blade body. Each tooth can include a tip, rake face, gullet having a gullet depth, and one or more clearance surfaces. The pitch distance and gullet depth of the heavy offset teeth can be less than the pitch distances and gullet depths of the remaining teeth to provide an increased amount of strength for the heavy offset teeth.

Abstract: A hydraulic tube expander includes expanding jaws engageable with an interior surface of a tube to expand the tube; a source of hydraulic fluid, a valve located between the source and the expanding jaws and a single-action release actuator operatively coupled to the valve. The valve is moveable between open and closed positions. In the closed position, hydraulic fluid can pass from the source to the expanding jaws and in the open position the hydraulic fluid can pass from the expanding jaws to the source. The actuator is movable between first and second positions. In the first position the valve is in the closed position. Movement of the actuator in a direction from the first position toward the second position moves the valve into the open position.

Abstract: A saw blade includes a plate with teeth. A tip pocket is formed in each of the teeth where the tip pocket has a first end and a second end and a continuously curved surface between the first end and the second end. A tip has a back face shaped to match the continuously curved surface. A joint joins the tip to the plate where the joint extends for substantially the length of the surface of the tip pocket and the back face. The continuously curved surface may have a wave profile. A top face of the tip and a peripheral face of the tooth may be coplanar.

Abstract: A step drill bit has a cutting head defining a longitudinal axis and having a plurality of steps having different effective diameters. First and second cutting edges are formed in the cutting head. The first cutting edge and the second cutting edge are arranged such that the bit is asymmetric in a plane perpendicular to the longitudinal axis relative to a plane containing the longitudinal axis. A rubbing surface is formed on each step where the rubbing surface extends to approximately the effective diameter of that step such that the first cutting edge, second cutting edge and the rubbing surface forms three points of contact with the side wall of the hole being cut.

Abstract: A chalk line is disclosed herein. The chalk line may include a housing, a track, and a door. The housing may define a chalk chamber and an opening in communication with the chalk chamber. The track may be disposed adjacent the opening and may include a curved section. The door may be movable between a closed position preventing access to the chalk chamber through the opening and an open position allowing access to the chalk chamber through the opening, and the door may include one or more door segments pivotably connected to one another by one or more hinges.

Abstract: A drill head is provided with three main cutting edges each having a straight direction of extension with a predominant radial direction component. The directions of extension limit two adjacent main bore dust discharge sectors, each spanning a main sector angle. Three drill head cutting legs each forming a main cutting edge where the three main cutting edges have different lengths along their directions of extension. Concentric ring shaped removal areas overlap at least partially such that a triple removal area coverage is provided in an outer ring zone and a double removal area coverage is provided in an inner ring zone.
