Dormer NC reamer B180 DIN 212 H7 B nominal Ø 8.2 mm HSS-E blank helical fluted

The NC reamer B180 DIN 212 H7 B with a nominal diameter of 8.2 mm is a high-precision tool specifically designed for machining holes with H7 tolerance. It features a slight left-hand spiral and a cylindrical shank, which enhance handling and machining accuracy. With an overall length of 117 mm and a cutting length of 33 mm, it is ideal for applications that require precise and clean machining. The reamer is made of HSS-E (high-speed steel) and is uncoated, making it particularly suitable for machining various materials such as carbon steel, steel alloys, cast iron, aluminum, and copper. The reamer is manufactured according to the DIN 212 standard and offers a working depth of 75 mm with a neck relief that increases efficiency during machining.

• Slight left-hand spiral for improved handling
• High-speed steel (HSS-E) for high wear resistance
• Suitable for precise machining according to DIN 212 standard
