Proffi's High speed steel drill bit set is made exclusively in Europe from best quality M2 steel, which is produced in Germany, France and Austria. Our drill bits are made from solid metal, while most of the manufacturers reduce costs by using the best quality metal only for tip of the drill bit. Furthermore each of the drill bit set quality is manually inspected to ensure maximum quality and reliability:
Perfect for metals, alloyed, constructional steels, cast iron, plastic and other materials.
Specially designed split-point for easy drilling start and great performance.
Made of M2 High Speed steel produced exclusively from three vendors: Erasteel (France); Beulmann (Germany); Boehler International (Austria).
Perfect hardness score (HRC - Rockwell scale): 62,5 - 63,5. Lower score results in lower durability; higher score results in fragility of a drill bit.
