The Dormer B400 DIN 8093 H7 Form B machine reamer is a precise tool specifically designed for machining holes with H7 tolerance. With a diameter of 5 mm and an overall length of 86 mm, this reamer provides an effective solution for various materials, including carbon steel, steel alloys, tool steel, cast iron, and aluminum. The unevenly divided, lightweight left-hand spiral 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 23 mm and a working depth of 58 mm offer high flexibility. This machine reamer is an essential tool for professionals seeking precise and efficient results in metalworking.
