HSS-G Cobalt 5% Drill Set – 25 pieces 1-13 mm | Cobalt drills

HSS-G Cobalt 5% Drill Set – 25 pieces (1–13 mm) is a professional drill set made of ground HSS-G with 5% cobalt for high heat resistance and up to 5–10× longer lifespan.

The self-centering drills start without a center punch, and the vacuum-oxidized surface reduces friction when drilling in steel, stainless steel, alloy steel, and cast iron. The set covers 1–13 mm in 0.5 mm increments – a complete kit for workshop and industry.
