Designs and diamond setting patterns have evolved through constant dialogue between this team and the World’s best drillers. Mined diamonds are selected from ethical and reliable sources, and blended to yield consistent characteristics. Matrix metallurgy has been optimized to give robust support to the diamonds, resulting in excellent retention and consequently a long and reliable life to the tool.
