The Dormer machine reamer with a diameter of 20 mm is a precise tool specifically designed for machining metal and other materials. This reamer is manufactured according to the BS 328 standard and offers high accuracy within the H7 tolerance range. It is made from high-quality HSS-E (high-speed steel) and features a bright steam-hardened surface that ensures enhanced durability and performance. The slight left-hand spiral of the cutting edges facilitates efficient chip removal and optimal machining results. With an overall length of 200 mm and a cutting length of 100 mm, this tool is ideal for various applications in metalworking, including the machining of carbon steel, steel alloys, cast iron, aluminum, and copper alloys. The reamer is equipped with an MK shank, allowing for easy mounting in machines.
