Abstract
A method for manufacturing cutting tools having diamond-like cutting edges or surfaces which are formed by bonding high shear compaction diamond or cubic boron nitride (CBN) ropes or strips in helical grooves formed on the cutting tool outer surface. The strips are formed by slitting a sheet of high shear compaction diamond or CBN material. The ropes are formed by rolling the strips between grooved rollers.
