The Dormer DIN 327 D long hole cutter is a high-precision tool specifically designed for milling long holes in various materials. With a nominal diameter of 12.5 mm and a working length of 27.5 mm, this cutter offers an optimal combination of efficiency and performance. The construction from HSS-E-PM (high-speed steel with powder metallurgy) ensures high wear resistance and durability, while the TiCN coating reduces friction and extends the tool's lifespan. The cutter is manufactured according to the DIN 327 D standard and features a 12 mm Weldon shank that guarantees secure attachment in the machine. With a helix angle of 30° and a rake angle of 12°, this cutter is ideal for applications such as shoulder milling, groove milling, and ramp milling in structural steel, carbon steel, cast iron, as well as in copper and titanium alloys. Its compact design and two cutting edges allow for precise cuts and high machining speeds.
