Dormer Deep hole twist drills DIN 1869 / 2 Type W A977 Nominal-Ø 14 mm HSS-E Cylindrical shank 20

The Dormer deep hole spiral drill DIN 1869 / 2 Type W A977 is a highly advanced tool specifically designed for drilling extremely deep holes. With a nominal diameter of 14 mm and an overall length of 390 mm, this drill offers superior performance when machining high-strength steels, cast steel, gray cast iron, and other demanding materials. The drill is made from HSS-E, which provides excellent heat hardness resistance, making it ideal for applications with high thermal stress. The parabolic flutes and heavily twisted spiral design ensure high efficiency and allow for drilling up to 20xD. The 130° point angle and profile-ground cross cutting edge contribute to optimal cutting performance, while the cylindrical shank ensures easy handling. This drill is therefore a reliable choice for professionals who require precision and efficiency in their drilling tasks.
