Abstract
A plurality of bushings are coupled to one another via a series of bolts to provide an interlocking, articulating cutter. The bolts have a cylindrical end and a convex end. The convex ends are seated inside a concave socket coupled to the bushings. The cylindrical ends are coupled to a convex nut seated inside another concave socket coupled to an adjacent bushing. The convex ends of the bolts are configured to articulate inside the seat of the concave sockets. A washer may be placed between the bushings to provide a desired amount of flexibility and/or rigidity. The outer surface of the bushing comprises a cutting structure, such as a milled or clad cutting structure.

A cutting apparatus comprising:
- a plurality of bushings, each bushing having a bore therethrough;
- a concave interior socket coupled to both ends of the bores of each of the plurality of bushings;
- and
- a bolt joining adjacent bushings, the bolt having a concave shouldered end and a cylindrical end, the concave shouldered end being seated inside the concave interior socket while the cylindrical end of the bolt is coupled to a convex nut, the convex nut being seated inside the concave interior socket of the adjacent bushing,
- wherein the plurality of bushing are configured to articulate in relation to one another.
A cutting apparatus comprising:
- a plurality of bushings, each bushing having a bore therethrough;
- and
- a bolt joining adjacent bushings, the bolt extending into a portion of the bore of the adjacent bushings, wherein the plurality of bushing are configured to articulate in relation to one another.
A method for cutting a structure, the method comprising the steps of:
- (a) bringing a cutting apparatus into contact with the structure, the cutting apparatus comprising:
- a plurality of bushings, each bushing having a bore therethrough;
- and
- a bolt joining adjacent bushings, the bolt extending into a portion of the bore of the adjacent bushings;
- (b) actuating the cutting apparatus along the structure;
- and
- (c) cutting the structure using the cutting apparatus.
