Steelwork HSS step drill / cone drill set 5 parts with tialn coating, lowering drill / metal drill for precise drilling of alloyed and non-alloyed steels including plastic storage box

Made with an extremely hard titanium aluminum nitrite (tialn) coating the HSS step drills master every challenge. The precision -cut bowling drill drill reliably into the metal to be processed. Due to the resistant Tialn coating, the lowering drills are very heat-resistant, wear-resistant and ensure long stands and a long service life. The coated step drills have up to 10 x higher service life compared to conventional HSS drills and are suitable for alloyed and unauthorized steels such as cast, N-metals and plastics. Due to their titanium aluminum nitrite coating, the cones have a high warm hardness and oxidation resistance. For safe transportation, the metal drills are well sorted in a robust plastic storage box. The different sizes of the cones are clearly applied on the cone drills themselves. The complete set consists of 5 step drills of different sizes. The cone drill set is particularly suitable for professional use in industry, craft and DIY.
