Hunger Expanding Reamer Type U
Right-hand cutting reamer with expanding blades. Exchangeable pilots at the front as well as at the back of the reamer. Each pilot is provided with square and sliding cone bush. A special bayonet coupling with mating cones between each pilot and the reamer body ensures correct alignment. Extension pilots are available in many different sizes. The blades are ground for taking a rough cut followed by finish reamer. Due to the unique Hunger relief grinding operation, the blades have a progressively increasing clearance angle, giving a softer cutting action. The adjustment nut is marked with a circular scale. One graduation of the scale corresponds to an alternation of the reamer diameter by 0,02mm.
The universal reamer for all types of holes, particularly for inline reaming of two or more holes. The cone bushes provide for exact alignment between the hole being rearmed and the other mating holes.
