Overview

The SEDIANAS Cobalt Drill Bit Set pairs premium M35 cobalt high-speed steel with precise manufacturing to deliver a durable, versatile kit for demanding drilling tasks. The cobalt content enhances heat resistance and hardness, helping the bits stay sharp longer when facing tough materials. Stored in a sturdy metal index box, this set keeps your bits organized and accessible for quick projects or busy workshops.

  • M35 cobalt composition offers improved heat resistance and hardness, which can extend tool life when drilling hard materials.
  • 135° split-point design promotes self-centering and reduces wandering for accurate starts.
  • Fully ground twist design facilitates faster chip clearance and cooler drilling by lowering friction and heat.
  • Extensive size range includes 29 fractional sizes from 1/16
