Abstract: It is proposed to prevent deformation of the tips of outer side walls of insert fitting recesses provided at the distal end of a jaw, thereby improving durability of the jaw and preventing breakage of the bolts. Insert fitting recesses (22) are formed on both sides of a movable jaw (4) movable between open and closed positions relative to the fixed jaw (3) at its distal end. Shear inserts (23) are fitted in the respective insert fitting recesses (22) and fixed in position by tightening bolts (30) for shearing an object (A) to be cut in cooperation with shear blades (12, 15 and 16) mounted at the distal end of the fixed jaw (3).

Abstract: A demolition cutter which can smoothly cut an object while eliminating the possibility of any gap being formed between mating surfaces having cutting edges. The cutter includes an arm pin 8 extending between a pair of side plates 6 of a movable bracket 3. Two arms 9a and 9b are mounted on the arm pin 8 so as to be pivotable about the pin 8 between open and closed positions. Cylinders 14a and 14b are connected to the arms 9a and 9b, respectively. The arms 9a and 9b have mating surfaces 11 formed with cutting edges adapted to cut an object when they cross each other. The cylinders 14a and 14b have their axes offset outwardly from the mating surfaces 11 so that when the cylinders are extended, the arms 9a and 9b are closed with their mating surfaces 11 in close contact with each other. This prevents the formation of a gap between the mating surfaces during cutting.
