Sada vrtákov NWKA 1-13 mm 25-dielna HSSE TiN INOX

This professional drill bit set from NWKA offers 25 high-performance twist drill bits made from HSSE-Co5 (high-speed steel with 5% cobalt) with a titanium nitride (TiN) coating. The set covers a diameter range of 1 mm to 13 mm in 0.5 mm increments, making it ideal for drilling in stainless steel (INOX), alloyed and unalloyed steel, cast iron, and non-ferrous metals. Each bit features a 135° point angle and cylindrical shank, fully ground for precision. Supplied in a robust metal case for storage and transport.

Advantages
