HSS vs Cobalt Drill Bits for Steel

HSS and cobalt drills can both cut steel, but the right choice depends on heat, hardness, speed and expected tool life.

Drill Bits for professional work

Cutting Tools Outlet organizes this selection by tool type, size, material and application so machinists, fabricators, maintenance teams, contractors and purchasing departments can reach the right configuration faster.

  • Use general-purpose HSS for routine work and cobalt for tougher alloys or higher heat.
  • Match the point geometry and coating to the holemaking operation.
  • Reduce speed and use lubricant when drilling heat-sensitive or work-hardening materials.
