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 10.05 mm and an overall length of 133 mm, this reamer provides an effective solution for creating fits with tight tolerances. 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 38 mm, while the working length is 87 mm, allowing for optimal machining depth. The reamer meets DIN 212 standards and offers a diameter tolerance of 0/+0.005 mm, making it ideal for precise applications in the mechanical engineering industry. It is suitable for machining various materials, including carbon steel, steel alloys, cast iron, aluminum, and copper.

• Slight left-hand spiral for improved machining efficiency
• Neck relief to reduce friction and enhance chip removal
• Suitable for creating fits with tight tolerances (10D8, 10E9, 10F10)
• Versatile for various types of metals and alloys.
