The NC reamer B481 from Dormer is a high-precision tool specifically designed for metal machining. With a nominal diameter of 3.97 mm and an overall length of 75 mm, this reamer offers an optimal combination of efficiency and accuracy. It is manufactured according to DIN 8093 and has a diameter tolerance of 0/+0.004 mm, making it ideal for producing fits. The solid carbide head is uncoated and is excellent for machining various materials, including steel alloys, tool steel, aluminum, and copper. The reamer features a strongly unevenly divided, light left-hand spiral design that ensures improved chip removal and a longer tool life. The special shape B and the neck relief grind allow for precise machining even in tight spaces.
