The NC reamer B481 DIN 8093 B from Dormer is a high-precision tool specifically designed for metal processing. With a nominal diameter of 3.98 mm and an overall length of 75 mm, this reamer provides an effective solution for creating fits within tolerances of 4N10 or 4N11. The reamer features an unevenly divided, light left-hand spiral that ensures optimal chip removal. The solid carbide head is uncoated and is excellent for machining various materials, including carbon steel, steel alloys, tool steel, cast iron, and aluminum. The reamer is standardized according to DIN 8093 and offers a diameter tolerance of 0/+0.004 mm, allowing for high precision during machining. The neck relief design enhances handling and efficiency during use.
