Product description

  • Size - Cutting edge diameter: 10mm / 25/64"; round shank diameter: 10mm / 25/64"; cutting edge length: 84mm / 3.31"; overall length: 133mm / 5.24"; split point: 135 degree (Fast cutting point penetrates quickly with less pressure and prevents walking on metal surfaces.) Material - 4241 high-speed steel provides excellent hardness, high strength, wear resistance and good heat resistance.
  • This helps ensure efficient, consistent drilling performance, and prevent overheating and extending the life of the drill bit.
  • Features - Black nitride coating can improve hardness, increase wear resistance and prolong its life.
  • The nitride coating also reduces friction in the drilling process, resulting in smoother and faster drilling performance.
  • Applications - Drill clean and accurate holes in stainless steel, cast iron, carbon steel, aluminum alloy, copper, and brass, wood and plastic.
  • Large spiral grooves facilitate the export of metal chips, saving time an effort. NOT suitable for tiles, concrete, walls, stones.
  • Note - Used with handheld drills, drilling machines, bench drills, machining centers, CNC lathes. Use an appropriate lubricant to reduce friction and heat build-up.
  • Make sure the drill bit is tightened securely, and keep the drill bit perpendicular to the work surface.
