Core drill made of high-performance high-speed steel with titanium-aluminum-nitride coating. The TiAlN wear protection coating increases the surface hardness of the tool to approximately 3,000 HV/microhardness and the hot hardness resistance up to 900 °C. It is characterized by high toughness as well as high thermal and chemical stability, contributing to longer tool life and better cutting values. Due to the TiAlN coating, the drill is suitable for dry machining. Particularly suitable for machining unalloyed and alloyed steels (up to 1200 N/mm²), high-chromium alloyed steels such as V2A and V4A, as well as cast steel and tough brass.

Contents: 6 pieces of core drills with Weldon shank (3/4") Ø 12, 14, 16, 18, 20, 22 mm, 1 guide pin Ø 6.35 x 77 mm for cutting depth of 30 mm. Additional technical specifications: 7-piece set, shank design: Weldon, cutting depth: 30 mm.

In a metal case.
