The Dormer machine reamer B400 DIN 8093 H7 Form B is a high-precision tool specifically designed for machining holes with H7 tolerance. With a nominal diameter of 3 mm and an overall length of 61 mm, this reamer provides an effective solution for various materials, including carbon steel, steel alloys, tool steel, aluminum, and copper alloys. The uneven pitch and slight left-hand spiral ensure consistent chip removal and reduce vibrations during the machining process. The reamer is made of high-quality carbide (HM) and is uncoated, making it ideal for machining free materials. The working length of 30 mm and the cutting length of 15 mm allow for precise machining, while the neck relief increases flexibility in application. This machine reamer is an essential tool for professionals who value precision and quality.
