Overview

Boost your drilling projects with the SEDIANAS cobalt drill bit set. Built around M35 cobalt high speed steel, these bits resist heat and stay sharp longer when working through hardened metals, stainless steel, cast iron, and tough plastics. The 29-piece assortment covers sizes from 1/16 to 1/2 inch in precise steps, ensuring you can tackle a wide range of tasks without swapping bits mid project. The included metal index storage box keeps each bit in its rightful place for quick size checks, protecting edges and preventing misplacement on a busy bench.

Why choose M35 cobalt bits

  • Premium heat resistance and increased hardness help maintain cutting edge during tougher jobs.
  • Designed to extend tool life by reducing heat buildup and wear during drilling.
