Product details

Universal spiral drill with high elasticity, very well suited for use in hand drills. It is designed for machining both alloyed and unalloyed steel. Even at larger diameters, it requires only a small feed pressure and offers the highest toughness with optimal cutting performance. At smaller diameters, the high elasticity results in a low risk of breakage. The optimized drilling geometry and the special Alpen grinding technique reduce drilling time by about one third, leading to a longer tool life. The tool's lifespan is further enhanced by the use of high-quality HSS steel and a special heat treatment.
