Steelwork HSS step drill / cone drill set 6 parts with TIN coating, creep drill / metal drill for precise drilling of alloyed and non-alloyed steels including automatic grains and aluminum case

Made with an extremely hard titanium nitrite coating (TIN), the HSS step drills master every challenge. The precision -cut bowling drill drill reliably into the metal to be processed. Due to the resistant TIN coating, the sink drills are heat-resistant, wear-resistant and ensure long stands and a long service life. The coated step drills have up to 400% higher service life compared to conventional HSS drills and are suitable for alloyed and unauthorized steels such as cast, N-metals and plastics. For safe transport, the metal drills are well sorted in a robust aluminum case. The different sizes of the cone are clearly listed on the cone drills themselves and in the aluminum case. The complete set consists of 5 step drills in different sizes and a high-quality automatic grain. The cone drill set is particularly suitable for professional use in industry, craft and DIY.
