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