Dormer Deep hole twist drills DIN 1869 / 1 Type W A976 Nominal-Ø 13 mm HSS-E Cylindrical shank 15

The Dormer deep hole spiral drill DIN 1869 / 1 Type W A976 is a highly advanced tool specifically designed for extremely deep drilling. With a nominal diameter of 13 mm and an extended version, this drill is ideal for applications that require high thermal stress. The drill is made from HSS-E, a high-quality cobalt steel alloy that offers excellent heat hardness resistance. The parabolic flutes and the highly twisted spiral design ensure high efficiency and allow for precise drilling up to 15xD. The 130° point angle and the profiled cross-cutting edge contribute to optimal cutting performance, while the cylindrical shank ensures easy handling. This drill is particularly suitable for machining high-strength steels, cast steel, gray cast iron, and ductile iron under challenging conditions.
