The NC reamer B481 DIN 8093 B with a nominal diameter of 4 mm is a high-precision tool specifically designed for metalworking. It features a strongly unevenly divided, light left-hand spiral and a cylindrical shank that allows for easy handling. With an overall length of 75 mm and a cutting length of 19 mm, it is ideal for applications that require high accuracy. The reamer is standardized according to DIN 8093 and offers a diameter tolerance of 0/+0.005 mm, making it particularly suitable for producing fits within the tolerances 4J7, 4J8, 4JS7, 4JS8, and 4JS9. The uncoated carbide head allows for the machining of a variety of materials, including carbon steel, steel alloys, tool steel, cast iron, and aluminum. This reamer is an essential tool for professionals who require the highest precision in their machining processes.
