If you burn through standard bits when drilling metal, this Sabre Tools 1/4″ cobalt drill bit set is a practical, budget-friendly upgrade. You get five matching 1/4″ x 4″ bits—ideal when you want consistent hole sizing and a few spares ready to go.

Built with M35 cobalt and designed for heavy-duty work, these bits are made to handle demanding materials while resisting abrasion and high heat. The 135° pilot point tip helps prevent slipping at the start of the hole, which can improve control and speed on hard surfaces.

Use them across a wide range of jobs—from repairs to construction projects—on metals and other materials like hard plastics and wood when appropriate.

  • Includes 5 identical bits: 1/4″ x 4″ (5-piece set)
  • M35 cobalt construction for durability and heat/abrasion resistance
  • 135° pilot point helps reduce walking and supports faster starts
  • Spiral flute design with 2 flutes
