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, low risk of breakage even with smaller diameters due to high elasticity, optimised drill geometry and the special ALPEN grinding shorten the drilling time by around one third, longer service life, which is increased by the use of the highest quality HSS steel and special heat treatment.
