AW STEP TWIST DRILL BIT M2-TiAlN / Set of 4 pcs. / 4-12mm / 4-20mm / 4-32mm / 4-39mm /BL

The STEP AW twist drill bit set includes four step bits covering ranges 4-12mm, 4-20mm, 4-32mm, and 4-39mm. Made from M2 high-speed steel with a titanium aluminum nitride (TiAlN) coating, these bits offer enhanced wear resistance and heat dissipation. The step design allows drilling multiple hole sizes with a single bit, ideal for sheet metal, wood, and plastics.

Each bit features a 135° split point that reduces walking and eliminates the need for a pilot hole. The 1/4" hex shank is compatible with standard quick-change chucks and impact drivers. The TiAlN coating extends tool life and enables higher cutting speeds. Suitable for both professional and DIY applications.
