Dormer NC reamer B180 DIN 212 H7 B nominal Ø 2.3 mm HSS-E blank helical fluted

The NC reamer B180 DIN 212 H7 B from Dormer is a high-precision tool specifically designed for metalworking. With a nominal diameter of 2.3 mm and an overall length of 53 mm, this reamer is ideal for applications that require high dimensional accuracy. The slight left-hand spiral and cylindrical shank facilitate efficient chip removal and improved machining quality. The cutting length of 12 mm and working length of 26 mm provide an optimal balance between stability and flexibility. Made from HSS-E (high-speed steel), this tool is uncoated and is excellent for machining carbon steel, steel alloys, cast iron, as well as aluminum and copper alloys. The reamer meets the requirements of the DIN 212 standard, making it a reliable choice for precise drilling in the H7 tolerance range.

• Slight left-hand spiral for improved chip removal
• Cylindrical shank for high stability
• HSS-E material for durability and efficiency
• Meets DIN 212 standard for precise machining.
