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 dust collector operable to collect dust and debris generated during operation of a power tool includes a mounting base configured to couple to the power tool. The mounting base defines a longitudinal axis. The dust collector also includes a shroud extending from the mounting base. The shroud includes a first end adjacent the mounting base, a second end operable to contact a workpiece, a sleeve extending between the first end and the second end, and a spring biasing the second end away from the first end. The second end is movable relative to the first end against the spring.

Abstract: A power tool system includes a power tool and a dust collector operable to collect debris generated during operation. The power tool includes a housing, a working end, and a tool bit extending from the working end. The dust collector includes a mounting base seated against the working end, a tether coupled to the mounting base, and a shroud extending from the mounting base. The mounting base defines an aperture through which the tool bit extends. The tether is wrapped around a portion of the housing to secure the dust collector to the power tool. The shroud has a first end adjacent the mounting base, a second end operable to contact a workpiece, a sleeve extending between the first end and the second end, and a spring biasing the second end away from the first end. The second end is movable relative to the first end against the spring.

Abstract: A chainsaw chain includes a plurality of drive links, a plurality of cutters, and a plurality of rivets. Each drive link includes a drive link body, a rivet hole extending through the drive link body, and a tang configured to engage a drive element of a chainsaw. Each cutter includes a cutter body having a rivet hole extending therethrough, a cutting tooth coupled to an upper portion of the cutter body, a carbide cutting tip coupled to the cutting tooth, a feed limiter coupled to the upper portion of the cutter body and spaced from the cutting tooth, and a gullet defined between the cutting tooth and the feed limiter. The plurality of rivets is received within corresponding rivet holes of the plurality of drive links and the plurality of cutters, to couple the plurality of drive links and the plurality of cutters together.

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 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. The drill bit further includes a plurality of cutting edges formed in the body. Each cutting edge is disposed along one of the plurality of steps and defines a helix angle and a rake angle. The helix angle of the cutting edge at the terminal step is greater than the helix angle of the cutting edge at the first step. A ratio of the helix angle to the rake angle of the cutting edge at the first step is in a range from 0.5 to 2.4, and a ratio of the helix angle to the rake angle of the cutting edge at the terminal step is in a range of 0.9 to 1.7.

Abstract: An attachment includes a body, an impact portion defining an impact axis and configured to receive repeated impacts from the powered hammer, and a driving portion including a side load driving portion and a top load driving portion that alternately receive the rod to transmit driving forces from the repeated impacts to the rod. The side load driving portion defines a side load driving axis that is offset from the impact axis. The top load driving portion includes a blind bore and defines a top load driving axis that is coaxial with the impact axis. The top load driving portion includes a sleeve disposed within the blind bore and configured to decrease wear of the blind bore during use.
