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 pair of rivet holes extending through the drive link body, and a tang extending from the drive link body and configured to engage a drive element of a chainsaw. Each cutter includes a cutter body having a pair of rivet holes extending therethrough, a cutting tooth coupled to an upper portion of the cutter body, a feed limiter, and a gullet. The cutter body defines a longitudinal axis extending through the pair of rivet holes and a vertical axis oriented perpendicular to the longitudinal axis. The cutting tooth is set relative to the vertical axis. The plurality of rivets couples the plurality of drive links and the plurality of cutters together.

Abstract: A fastener driver includes a shank and a socket. The socket includes a first engagement portion with a first fastener and a second engagement portion engageable with a second fastener. The first fastener is different than the second fastener. The socket is movable relative to the shank between a first position, in which the first engagement portion is usable to engage the first fastener, and a second position, in which the second engagement portion is usable to engage the second fastener. The socket is movable between the first and second positions without physically separating the socket from the shank.

Abstract: A drill bit includes a body having a first end, a second end opposite the first end, and an axis of rotation extending centrally though the body from the first end to the second end. The body defining an outer diameter. The drill bit also includes a shank adjacent the second end of the body configured to couple to a tool and a cutting head adjacent the first end. The cutting head includes a plurality of axially stacked, progressively sized steps including a first step and a terminal step positioned between the first step and the first end of the body. The steps increase in diameter from the first step to the terminal step. The terminal step having a diameter that is less than or equal to the outer diameter.

Abstract: A drill bit includes a body having a first end, a second end opposite the first end, and an axis of rotation extending centrally through the body. The drill bit includes a cutting head with a cutting tip on the axis of rotation and a cutting portion. The cutting portion includes first tip surfaces on opposite sides of the axis of rotation and second tip surfaces on opposite sides of the axis of rotation. Each first tip surface extends radially outward from the cutting tip to a corresponding second tip surface. Each second tip surface extends from a corresponding first tip surface to an outer periphery of the body. The first tip surfaces define a first tip angle measured through the axis of rotation that is oblique. The second tip surfaces define a second tip angle measured through the axis of rotation that is smaller than the first tip angle.

Abstract: A method of manufacturing a drill bit includes providing a piece of bar stock having a first end, a second end opposite the first end, and an axis of rotation extending centrally through the bar stock between the first and second ends, cutting the first end of the bar stock to form a first tip angle at an oblique angle measured through the axis of rotation, cutting the first end of the bar stock at a second tip angle measured through the axis of rotation to form first tip surfaces and second tip surfaces. The first tip surfaces have the first tip angle and the second tip surfaces have the second tip angle. The second tip angle is smaller than the first tip angle. Finally forming a flute in the bar stock between the first and second ends and forming a shank at the second end of the bar stock.

Abstract: A device may include a housing. A device may include a shank supported by the housing, the shank extending along a first axis and including a tool coupling portion configured to couple to the tool. A device may include a tool bit adapter supported by the housing along a second axis, the tool bit adapter being pivotable relative to the housing such that the second axis is disposed at a plurality of angles relative to the first axis. A device may include a transmission assembly positioned within the housing, the transmission assembly configured to convert an input torque about the first axis from the tool to an output torque about the second axis acting on the tool bit.

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.
