Features:<\/h3>The RDS turning tool operates according to the Hunger precision turning process, which has been proven 100,000 times over. It is equipped with both horizontal and vertical feed, allowing the bottom surface of the counterbore to be face-turned and the cylindrical wall surface to be bored to the required dimension.The maximum boring diameter can be preset using an adjustable stop.A pilot clamped into the valve guide centers the turning tool.For additional support of the turning tool, which is centered and guided by the pilot, a self-aligning guide is provided below the hand crank. This is fixed with a steady rest or to the cylinder head clamping fixtures available from Hunger.\t\t\t\t\t\t\t\t<\/div>\n\t\t\n<\/div>\n
