HSS-G Cobalt 5% Drill Set – 70 pieces 1–10.2 mm | Cobalt drills

HSS-G Cobalt 5% Drill Set – 70 pieces (1–10.2 mm) is an advanced drill set that uses high-alloy high-speed steel with 5% cobalt for a lifespan up to 5–10 times longer than regular HSS drills.

The drills are self-centering thanks to a specially ground tip, eliminating the need for a center punch. The vacuum-oxidized surface reduces friction and improves performance when drilling demanding materials. The set is ideal for drilling in steel, stainless steel, alloy steel, and cast iron.
