SET OF 3PCS Cobalt Step Drill Bit

  • The addition of cobalt to M35 HSS significantly improves wear resistance, allowing for smooth cutting through stainless steel, aluminum, copper, plastic, wood, and a variety of other materials.
  • These cobalt drill bits are made from high-strength M35 HSS steel, featuring a spiral groove and hexagonal shank design for faster, more stable, and smoother operation. The hex shank ensures secure insertion into power tool chucks, preventing slippage.
  • The metal cutter fits securely into power tool chucks, reducing slippage. Its double-edged design promotes faster chip removal, ensuring efficient particle expulsion and minimizing breakage. Suitable for deburring, chamfering, and hole cutting.
  • Provides up to 3 times faster performance.
