Abstract: An extension adapter includes a body, a collar, and a gasket. The body includes a front portion, a rear portion, and a flange separating the front portion from the rear portion. The front portion has a larger diameter than the rear portion. The body also includes an inner surface that defines a bore configured to receive a tool bit. The collar is moveable along the rear portion of the body between an unlocked position in which the tool bit is removable from the bore and a locked position in which the tool bit is secured to the body. The gasket is coupled to the rear portion of the body and abutting the flange. The gasket is compressed between the flange and the collar when the collar is in the locked position to block dust and debris from entering the bore.

Abstract: A hand tool for driving a fastener is provided. The hand tool includes gearing that interconnects a splined socket to a rotatable or trigger actuator and increases a rotational speed of the splined socket relative to the actuator. The hand tool may include a power tool receiver 38 or an independent motor to drive rotation of the splined socket to advance or retract a fastener from a threaded shaft. By increasing the speed and conserving rotational inertia, the hand tool reduces the time to secure a fastener on a threaded shaft. A rotatable nut is provided. The rotatable nut can slideably orient along a first axis and threadedly orient along a second axis to fasten to an adjacent surface.

Abstract: An extension adapter includes a body having a bore. The bore is configured to receive a tool bit. The extension adapter includes a retaining member received within an aperture of the body and a biasing member coupled to the body. The biasing member includes a protrusion received within the aperture to bias the retaining member into a first position in which a portion of the retaining member extends into the bore. The extension adapter includes a collar moveable between an unlocked position and a locked position. The unlocked position is configured to allow the tool bit to be removed from the bore. While the collar is maintained in the locked position, the body is configured to slidably receive the tool bit such that the portion of the retaining member is received in a groove of the tool bit to secure the tool bit to the body.

Abstract: A step drill bit includes a shank and a body that defines a plurality of axially stacked, progressively sized steps including a first step, a terminal step, and a plurality of intermediate steps having incrementally increasing diameters disposed between the first and terminal steps. The step drill bit includes a flute in the body extending from the distal end to the proximal end and a plurality of cutting edges formed in the body. Each cutting edge is disposed along one of the plurality of steps. Each cutting edge defines a helix angle and a radial rake angle. The helix angle of the cutting edge at a first intermediate step of the plurality of intermediate steps is greater than the helix angle at the first step. The radial rake angle of the cutting edge at the first intermediate step is greater than the radial rake angle at the first step.

Abstract: A step drill bit includes a shank and a body having a proximal end adjacent the shank and a distal end opposite the proximal end. The body defines a plurality of axially stacked, progressively sized steps including a first step at the distal end, a terminal step at the proximal end, and a plurality of intermediate steps having incrementally increasing diameters disposed between the first and terminal steps. The step drill bit also includes a plurality of cutting edges each disposed along one of the plurality of steps. Each edge defines a helix angle and a radial rake angle. The radial rake angle and the helix angle of the cutting edge at the terminal step is greater than the radial rake angle and the helix angle of the cutting edge at the first step.

Abstract: A hole saw includes a cylindrical body having a sidewall with a first end and a second end opposite the first end. The cylindrical body includes a gullet formed in the sidewall between a leading surface, a trailing surface, and a bottom surface of the sidewall. The gullet defines a central longitudinal axis extending between the first and second ends of the sidewall that is obliquely oriented relative to a rotational axis of the hole saw such that the gullet is angled from the first end to the bottom surface in a direction toward a cutting direction of the hole saw. The gullet has a dimension measured parallel to the rotational axis between the first end of the sidewall and the bottom surface of the gullet that is greater than 1.5 inches. The hole saw includes a cutting tooth coupled to the first end of the sidewall adjacent the gullet.

Abstract: A door hardware locating tool includes an edge wall having a first side, a second side opposite the first side, and an edge bore aperture that extends through the first and second sides. The edge bore defines a first axis that extends centrally through the edge wall and through the first and second sides. The door hardware locating tool also includes a side wall adjacent the edge wall. The side wall includes a first side, a second side opposite the first side, and a cavity defined between the first and second sides. The door hardware locating tool further includes an insert at least partially positioned within the cavity of the side wall. The insert is rotatable about a second axis that is perpendicular to the first axis between a first position and a second position. The insert includes a cross bore aperture.

Abstract: A drill bit includes a shank extending along a bit axis and a body with a proximal end adjacent the shank and a distal end opposite the proximal end. The body defines a plurality of axially stacked, progressively sized steps including a first step at the distal end and a terminal step at the proximal end. The drill bit also includes a flute in the body. The flute defines an elongated groove that extends from the distal end to the proximal end.
