摘要： An attachment configured for use with a powered hammer to drive a rod into the ground includes a body, an impact portion, and a driving portion in which the rod is receivable. The impact portion defines an impact axis and includes a bore configured to receive a driving shank coupled to the powered hammer. The impact portion is configured to receive repeated impacts from the powered hammer. The driving portion includes a side load driving portion defining a side load driving axis that is parallel to the impact axis. The driving portion further includes a top load driving portion defining a top load driving axis that is parallel to the side load driving axis.

摘要： A chainsaw cutter for a chainsaw chain. The chainsaw cutter includes a cutter body having a pair of rivet holes extending through the cutter body. The chainsaw cutter further includes a cutting tooth coupled to and extending from an upper portion of the cutter body. The cutting tooth is configured to cut a workpiece during a cutting operation. Moreover, the chainsaw cutter includes a feed limiter coupled to and extending from the upper portion of the cutter body, and a gullet disposed between the cutting tooth and the feed limiter. The cutting tooth is formed on the cutter body by additive manufacturing.

摘要： 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.

摘要： 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.

摘要： 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.
