Abstract
A power shear tool includes a housing portion, a motor positioned within the housing portion, and a tool head portion extending from the housing portion and including a blade rotatable relative to the tool head portion. The power shear tool includes a workpiece support member positioned proximate the tool head portion. The workpiece support member includes a top surface and a bottom surface opposite the top surface, side surfaces extending between the top and the bottom surfaces, a first channel defined in the top surface and extending from at least one of the side surfaces, and a second channel defined in the top surface. The second channel intersects the first channel and extends transverse to the first channel.
Claims13
A power shear tool comprising:
- a housing portion;
- a motor positioned within the housing portion;
- a tool head portion extending from the housing portion and including a blade rotatable relative to the tool head portion;
- and
- a workpiece support member positioned proximate the tool head portion, the workpiece support member including,
- a top surface and a bottom surface opposite the top surface,
- side surfaces extending between the top and the bottom surfaces,
- a first end surface extending between the side surfaces, the first end surface positioned adjacent the tool head portion,
- a second end surface extending between the side surfaces, the second end surface positioned opposite from the first end surface,
- a first channel defined in the top surface and extending from at least one of the side surfaces, the first channel proximate the first end surface,
- a second channel defined in the top surface, the second channel intersecting the first channel and extending transverse to the first channel, and
- a third channel spaced apart from and generally parallel to the first channel, the third channel defined in the top surface of the workpiece support member, the third channel proximate the second end surface, the second channel intersecting the third channel and extending transverse to the third channel,
- wherein each of the first channel and the third channel is configured to receive a portion of a workpiece at the same time,
- wherein the second channel has a longitudinal width extending between an edge of the first channel and an edge of the third channel, and
- wherein the blade is configured to be received within the entire longitudinal width of the second channel between the edge of the first channel and the edge of the third channel.
A power shear tool comprising:
- a housing portion;
- a motor positioned within the housing portion;
- a handle including a grip positioned adjacent to the housing portion;
- a tool head portion extending from the housing portion and including a blade rotatable relative to the tool head portion, the blade including a flat arcuate cutting edge portion having a first end and a second end, and a piercing portion having two substantially linear edges that meet at a piercing point, at least one of the substantially linear edges extending from the second end of the cutting edge portion;
- and
- a workpiece support member positioned proximate the tool head portion, the workpiece support member including,
- a top surface and a bottom surface opposite the top surface,
- side surfaces extending between the top and the bottom surfaces,
- a first channel defined in the top surface and extending from at least one of the side surfaces,
- a second channel spaced apart from and generally parallel to the first channel, the second channel defined in the top surface;
- a third channel defined in the top surface, the third channel intersecting the first channel and the second channel and extending transverse to the first channel and the second channel, and
- a pair of lateral sides defining the third channel, wherein a shearing edge is positioned along each lateral side of the third channel,
- and
- wherein the third channel is configured to receive the piercing point of the piercing portion which is the first point of contact between the blade and a workpiece.
