Universal twist drill, high elasticity, very well suited for use in hand drills, for machining alloyed and unalloyed steel, low feed pressure required even for larger diameters and highest toughness with optimum
cutting performance, even with smaller diameters low risk of breakage due to high elasticity, optimised drill geometry and the special ALPEN grinding shortens the drilling time by about one third, longer tool life, which is increased by using the highest quality HSS steel and a special heat treatment.
