The NC reamer B481 DIN 8093 B from Dormer is a high-precision tool specifically designed for metal machining. With a nominal diameter of 4.01 mm and an overall length of 75 mm, this reamer provides an optimal solution for creating fits within tolerances of 4G7 or 4H8. The reamer features a strongly unevenly divided, light left-hand spiral, which allows for efficient chip removal. The solid carbide head is uncoated and is excellent for machining various materials, including 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, ensuring high accuracy in machining. With a cutting length of 19 mm and a working length of 47 mm, it is ideal for precise applications in metalworking.
