Claim:
A heavy-duty demolition shear with a replaceable shearing tip, the apparatus having a lower jaw and an upper jaw pivotally connected to the lower jaw, the upper jaw having a shearing blade, comprising: (a) a tip mounting portion on the upper jaw, the shearing blade having a cutting edge on a lower, planar shearing surface and a tip mounting surface, the tip mounting surface meeting the cutting edge an acute angle to the cutting edge; (b) a replaceable shearing tip mountable to the tip mounting portion, wherein the replaceable shearing tip further comprises two sections encompassing the tip mounting portion there-between, wherein the two sections are L-shaped and having a first arm and a second arm, the first arm and the second arm each comprising a continuous planar surface; (c) wherein the first arm of the L meets the cutting edge of the shearing blade at an oblique angle; wherein the upper jaw further comprises at least three seats for engaging the replaceable shearing tip, wherein one of the at least three seats is the tip mounting surface of the shear blade, and wherein the replaceable shearing tip abuts firmly against the tip mounting surface without a gap; and (d) wherein the continuous planar surface of the second arm of the L forms a dihedral angle with the plane of the shearing surface of the shearing blade.
