HSS-G Cobalt Drill – Cobalt drill 1–13 mm | 5- & 10-pack

HSS-G Cobalt Drill (HSS-Co 5%) is a premium drill for demanding use. Its special grinding makes the drill self-centering, meaning you can drill directly without a center punch.

Thanks to the high-alloy 5% cobalt steel, the drill has a 5–10 times longer lifespan than a regular HSS drill. The surface is vacuum-oxidized, which reduces friction and enables more efficient drilling even in tough materials.
