HSS-G Cobalt Drill – Cobalt drill 1–13 mm | Sold individually

HSS-G Cobalt Drill (HSS-Co 5%) is a durable premium drill bit for professional use. The self-centering grind provides immediate precision without walking, even on hard surfaces.

Made from high-alloy cobalt steel 5%, it offers a 5–10× longer lifespan than standard drill bits, and the vacuum-oxidized surface reduces friction for faster, cooler drilling.

Perfect for steel, stainless steel, alloy steel, and castings, where high heat resistance and fracture toughness are crucial. Available in sizes 1–13 mm in 0.5 mm increments and sold individually.
