Abstract
A blade support assembly for use with a casing cutter to cut through casing or pipe downhole in a well. A tubular body fits over the casing cutter, with slots aligned with the pivoting cutter blades. Support plates next to each slot provide support for the blades during cutting operations. Torque keys and matching torque slots in the blade support assembly and the casing cutter body transfer torque from the casing cutter body to the blade support assembly, and thence to the blades.
