The spiral drill DIN 1897 Type ADX A520 is a high-precision tool specifically designed for machining steel, stainless steel, cast iron, and non-ferrous metals. With a nominal diameter of 12.1 mm and an overall length of 102 mm, this drill features a cutting length of 51 mm, manufactured according to the DIN 1897 standard. The TiN coating (titanium nitride) enhances wear resistance and extends the tool's lifespan. The drill is equipped with a 130° point angle and a spiral grind of 25-30°, ensuring efficient chip removal and high drilling quality. Dormer's special ADX geometry allows for increased performance and precision during machining. The cylindrical shank of the drill is designed for easy handling and compatibility with various drilling machines, while the right-hand cutting direction enables user-friendly application.
