The NC reamer B481 from Dormer is a high-precision tool specifically designed for metal machining. With a nominal diameter of 5.03 mm and an overall length of 93 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 within the tolerances of 5E8, 5F9, or 5H10. The solid carbide (VHM) head is uncoated and allows for the machining of a variety of materials, including carbon steel, steel alloys, tool steel, cast iron, and aluminum. The special left-hand spiral and the relieved neck enhance chip removal and extend the tool's lifespan. This reamer is therefore an excellent choice for applications that require the highest precision.
