High-quality finishing shell reamer 47 H7 machine reamer, NRNb, with a size of 47 mm, designed for final machining of cylindrical holes in H7 tolerance. It is a finishing reamer, conforming to the DIN 219 dimensional standard, made according to the latest standards from special high-grade HSS. The machine reamers we offer are multi-flute, chip-slotted tools aimed at fine machining of holes. They are used after the holes have been previously drilled with a drill and reamer ripper. The tools in our store are designed to adjust the diameter of the hole to meet specific dimensional needs, bring out the axis of the hole, level unevenness on the surface of the hole, and reduce roughness. The machine reamers offered in our store are suitable for machining carbon steel, metals, nonferrous metals, metal alloys and plastics. They can be used for various types of conventional and CNC computer-controlled machine tools.
