The Dormer B101 BS 328 H7 Form B machine reamer is a high-precision tool specifically designed for metalworking. With a nominal diameter of 28 mm and an overall length of 251 mm, this reamer provides an effective solution for creating precise holes with H7 tolerance. The HSS-E (High-Speed Steel) construction ensures high wear resistance and durability, while the bright steam-hardened surface enhances machining efficiency. The slight left-hand spiral allows for improved chip removal and ensures uniform machining. This machine reamer is ideal for use on various materials, including carbon steel, steel alloys, cast iron, aluminum, and copper alloys. It is an essential tool for professionals who value precision and quality.
