Dormer NC reamer B180 DIN 212 H7 B nominal Ø 2.1 mm HSS-E blank helical fluted

The NC reamer B180 DIN 212 H7 B with a nominal diameter of 2.1 mm is a precise tool specifically designed for machining holes with H7 tolerance. Made from high-quality HSS-E (high-speed steel), this reamer offers excellent performance when working with various materials, including carbon steel, steel alloys, cast iron, aluminum, and copper. The slight left-hand spiral and cylindrical shank enable efficient chip removal and improved surface quality. With an overall length of 49 mm and a cutting length of 11 mm, it is ideal for applications that require precise and clean machining. The reamer is uncoated, making it particularly suitable for free machining. Its construction according to DIN 212 ensures compliance with high manufacturing standards.

• Slight left-hand spiral for improved chip removal
• High-speed steel (HSS-E) for high wear resistance
• Suitable for a variety of materials, including aluminum and copper
• Neck relief for optimal machining depth and precision.
