Cobalt Boring Bars
Made of premium cobalt high speed steel in a one piece construction,
these boring bars may also be modified to a special grooving tool to
produce various internal shapes and radii. Cobalt is an ideal tool
material because of its high red-hardness, abrasive resistance and
ability to maintain a sharp edge. In addition, cobalt is used
successfully to significantly extend tool life.
