The machine reamer B170 DIN 212 Form B with a nominal diameter of 12 mm is a precise tool designed for machining metal and other materials. It features a slight left-hand spiral and a cylindrical shank, which facilitate handling and application. With an overall length of 151 mm and a cutting length of 44 mm, it offers an effective working length of 105 mm. This reamer meets DIN 212 standards and has a diameter tolerance of 0/+0.005 mm, making it ideal for producing fits within the tolerances of 12J7, 12J8, 12JS7, and 12JS8. Made from HSSE-Co (high-speed steel with cobalt) and uncoated, this tool is suitable for machining various materials, including carbon steel, steel alloys, cast iron, aluminum, and copper alloys. The machine reamer is thus a versatile tool for professional applications in metalworking.
