The Asahi helical pad reamer offers a 3 in 1 concept by incorporating natural diamonds and tungsten carbide set in a mixture of impregnated diamond matrix. This formula meets the criteria of most drilling applications from the more abrasive to the fine grained formations encountered world wide.

The new helical pattern incorporate a gentle taper from the leading edge, up to the major parallel section of the reamer, which is set to the standard hole size. This feature allows a much smoother and more gradual approach to the set size, resulting in extended life.
