The Dormer B170 DIN 212 Form B machine reamer is a precise tool designed for metalworking. With a nominal diameter of 9.99 mm and a working length of 87 mm, this reamer is ideal for applications requiring high dimensional accuracy and surface quality. The reamer is made from high-quality HSS-E (high-speed steel), ensuring excellent wear resistance and durability. The slight left-hand spiral and cylindrical shank allow for efficient chip removal and improved machining performance. The reamer meets DIN 212 standards and offers a diameter tolerance of 0/+0.005 mm, making it particularly suitable for the production of fits. It can be used for various materials such as steel, cast iron, aluminum, and copper alloys.

• High-quality HSS-E material for high wear resistance
• Slight left-hand spiral for improved chip removal
• Meets DIN 212 standards with precise diameter tolerance
• Suitable for a variety of materials, including steel and aluminum.
