The machine reamer B170 DIN 212 Form B with a nominal diameter of 5 mm is a precise tool designed for machining metal and other materials. Made from high-quality HSS-E (high-speed steel), this reamer offers excellent performance and durability. It is ideal for applications requiring tight tolerances and allows for the creation of fits within tolerances 5J7, 5J8, 5JS7, 5JS8, and 5JS9. The reamer features a slight left-hand spiral and a cylindrical shank, making it easier to handle and insert into machines. With a working length of 52 mm and an overall length of 86 mm, it is versatile and suitable for various materials, including carbon steel, steel alloys, cast iron, aluminum, and copper alloys. This reamer is uncoated, providing high flexibility in machining.
