A scissors attachment can also be attached to the reciprocating tool for cutting one or more sheets of material. The scissors attachment includes an extension bar and first and second blades pivotally attached. A tool chuck coupling connects one of the blades to the reciprocating tool chuck of the reciprocating tool. A bar slot can be integrally defined on the tool or defined on the neck mount assembly for receiving and securing in place the extension bar. A method of stabilizing a cutting instrument is also provided. Additionally, a method of cutting material is provided.

A cutting arm includes a base having a post receiving passageway extending through the base, a cutting assembly attached to the base, and a sliding plate attached to the base and movable with respect to the base between an engaging position and a releasing position. The sliding plate engages a post disposed in the post receiving passageway in the engaging position and releasably secures the cutting arm to the post.

A one piece four-sided hardened steel boot tip for a distal end upper jaw tang of a heavy duty demolition shear having a upper movable shear jaw with a shear tip or tang, a shear side and a guide side pivotally connected to a lower fixed or movable shear jaw with a shear blade side, a guide side, a distal tie plate and a recess therebetween. The tang has a front edge, side faces with apertures therethrough, a radiused top seat, a radiused rear seat and a radiused bottom seat. The boot tip has a front wall seated on the tang front edge and a right side wall seated on the shear side tang face and radiused rear seat. A top wall has a radiused inside top wall that sits on radiused top seat. A bottom wall of the boot tip has a radiused inside top wall that is seated on the tang radiused bottom seat forming a shear punching edge between the front wall and the bottom wall. A shear side shearing edge is between the sidewall and the bottom wall of the boot tip. An access or side plate is seated on the guide side tang face, a portion of the radiused boot bottom wall and the radiused rear seat. The side plate us flush with the bottom and front walls. The boot tip right side and access plate have matching apertures therethrough and alignable with the tang apertures to secure the boot and access plate to the tang for protection thereof from the lower jaw shear side, the guide side and the tie plate as the upper jaw moves into and out of the recess. One or more shims are provided and insertable inside the boot against the tang faces and clampable thereto after the faces have become worn or otherwise requires adjustment for maximum clamping force. An extendable boss maybe insertably located on the lower inside face of the side plate as to index and interlock with a matching indexing bolt or boss recess on tank guide side face. A portion of the lower edge of the side plate has a guide side shearing edge.

A replaceable tip for a demolition tool tip may include a first sidewall having a first contact side; a second sidewall having a second contact side; and a center wall connecting the first sidewall and the second sidewall. The center wall may have a third contact side provided with a recess, the recess may have first and second abutment surfaces, and the third contact side may have a third abutment surface adjacent the recess. A channel may be defined by the first, second and third contact sides, and the channel may be configured to receive an adapter of the demolition tool.

A jaw of a jaw set used for demolition, recycling, or material processing equipment with indexable and interchangeable cutting blades that abut with one another to form an apex angle. A jaw set with such a jaw is also included.

A tip assembly for a jaw of a jaw set for demolition and construction equipment has a base with a top side, an underside, and a protrusion extending along a longitudinal axis and extending from the underside. The tip also has a first insert mounted to the base and a second insert mounted to the base. Each insert has a first wall and an opposing second wall with a front side extending therebetween. Each insert also has a locking recess that conforms to the protrusion to limit movement of the insert in directions perpendicular to the longitudinal axis.
