The Dormer B170 DIN 212 Form B machine reamer is a precise tool designed for machining metal and other materials. With a nominal diameter of 6.05 mm and an overall length of 101 mm, this reamer provides an effective solution for creating fits within the tolerances of 6D9 or 6H11. The reamer is made of HSS-E (high-speed steel) and features a slight left-hand spiral along with a cylindrical shank, enhancing handling and machining efficiency. The cutting length is 28 mm, while the working length is 63 mm, allowing for optimal machining depth. This reamer is ideal for machining carbon steel, steel alloys, cast iron, aluminum, and copper as well as their alloys. It meets DIN 212 standards and offers a diameter tolerance of 0/+0.005 mm, ensuring precise results.
