The machine reamer B170 DIN 212 Form B with a nominal diameter of 4.01 mm is a precise tool designed for machining metal and other materials. Made from high-quality HSS-E (high-speed steel with an alloy), this reamer offers excellent performance and durability. With an overall length of 75 mm and a cutting length of 19 mm, it is ideal for applications that require high accuracy. The slight left-hand spiral and cylindrical shank allow for efficient chip removal and improved machining quality. The reamer meets DIN 212 standards and provides a diameter tolerance of 0/+0.004 mm, making it particularly suitable for producing fits within the tolerances of 4G7 or 4H8. It is versatile and suitable for machining various materials, including carbon steel, steel alloys, cast iron, and aluminum.
