The Dormer B442 DIN 8051 H7 Form A machine reamer is a high-precision tool specifically designed for machining holes with H7 tolerance. With a nominal diameter of 12 mm and an overall length of 182 mm, this reamer provides an effective solution for various materials, including carbon steel, steel alloys, tool steel, cast iron, and aluminum. The unevenly spaced straight flute ensures uniform chip removal and improved surface quality. The reamer is made from high-quality solid carbide (VHM) and is uncoated, making it ideal for machining free forms. The neck relief design allows for deeper machining, while the cutting length of 19 mm and working length of 116.5 mm offer high flexibility in application. This machine reamer is an essential tool for professionals seeking precise and efficient results in metalworking.
