Features and Benefits: * Blairs Double-End Spotweld Cutter with twice the tool life is the unique 3/8 diameter hardened and precision ground cutting tool that makes removing spot welded body panels fast and easy. * Hollow design cuts around weld, thus hardness does not affect tool sharpness. * An adjustable depth rod sets the tool so only the outer panel is cut through, leaving the underlying panel undamaged. * Double-End Cutters are packaged in sets of three. * When one end becomes dull, simply unscrew the cutter from the arbor, and reassemble with the new teeth exposed. * With arbor, for use in any 1/4, 3/8, or 1/2 chuck hand held drill.
