Universal twist drill with high elasticity, ideal for use in hand drills for machining alloyed and unalloyed steel. Even with larger diameters, it requires little feed pressure and offers the highest toughness with optimum cutting performance. For smaller diameters, there is a low risk of breakage due to its high elasticity. The optimized drill geometry and special ALPEN grinding reduce drilling time by about one third, while also extending tool life. The use of high-quality HSS steel and a special heat treatment further enhances durability.
