The Dormer B170 DIN 212 Form B machine reamer is a high-precision tool specifically designed for metalworking. With a nominal diameter of 4.03 mm and an overall length of 75 mm, this reamer provides an effective solution for creating fits in various types of metal. The slight left-hand spiral and cylindrical shank allow for optimal chip removal and improved machining quality. The reamer is made from HSS-E (high-speed steel), which enhances its durability and resistance to high temperatures and mechanical stresses. It meets DIN 212 standards and offers a diameter tolerance of 0/+0.004 mm, making it ideal for precise applications. The reamer is suitable for machining carbon steel, steel alloys, cast iron, aluminum, and copper, as well as their alloys. With a cutting length of 19 mm and a working length of 43 mm, it is versatile and enables efficient machining.
