The Century Drill & Tool 26310 is a 10-piece cobalt drill bit set made from industrial-grade M35 steel with 5% cobalt content — the composition that lets the bits cut through stainless steel, hardened metals, and other tough materials that chew up standard HSS bits. The sizing runs from 1/16 inch through 1/4 inch in 1/64-inch increments, which gives precise sizing for tapped holes and fasteners across the range a metalworker uses day to day.
Each bit has a 135° quick-cut point that is self-centering — it requires less pressure to start the cut, eliminates the need for a center punch on most materials, and prevents the walking or wandering that produces a misdrilled hole. The cobalt composition also resists the high heat generated during metal drilling, so the bit keeps its hardness and cutting edge through repeated holes.
Century Drill & Tool manufactures in the United States, and the 26310 set reflects the company’s commitment to pro-grade quality for tradespeople and machinists.
