The set, from the company TAGRED, consists of 13 drills in sizes 1.5 - 6.5 mm, made of metal with titanium coating. They are suitable for drilling in steel, cast iron, non-ferrous metals, and plastics. Titanium drills, unlike white drills, are characterized by greater durability and lower friction. 

The drills have a tip angle of 118°, so there is no need for hole marking before proper drilling.
