About this item

  • Drill Bit Size: Cutting Diameter: 20mm / 0.79"; Shank Diameter: 1/2"; Cutting Edge Length: 65mm / 2.56"; Overall Length: 160mm / 6.3"; Hardened to: HRC62-65. Black oxide coating increases durability, corrosion resistance and lubricity, and helps to reduce friction and heat.
  • M2-6542 High Speed Steel: M2-6542 high speed steel (M2 high speed steel with 5% cobalt) provides an excellent combination of hardness, wear resistance, and toughness. Adding cobalt can improve red hardness and heat resistance.
  • Reduced Shank: Reduced shank drill bit expands the size range capacity of drill chucks. Allows you to efficiently drill larger diameter holes without exceeding the capacity of the chuck. Make sure the drill bit is tightened securely into the chuck.
  • Wide Applications: Drill clean and accurate holes in stainless steel, cast iron, A3 steel, carbon steel, aluminum, copper, wood and plastic. The sharp cutting edges provide neat and smooth cuts. Large spiral grooves facilitate the export of metal chips, saving time and effort.
  • Notices: Use a marker or hole punch to mark the exact location, this will help guide your drilling accuracy. Start the drill at a slow speed and gradually increase to the desired drilling speed. Apply steady pressure to the drill. Keep the drill perpendicular to the work surface.

Reduced Shank Drill Bit

Expands the size range capacity of drill chucks. Allows you to efficiently drill larger diameter holes without exceeding the capacity of the chuck.

Black Oxide Finish

Black oxide coating increases durability, corrosion resistance and lubricity, and helps to reduce friction and heat, extending the tool life.

Sharp Spiral Flutes

The sharp cutting edges provide neat and smooth cuts. Large spiral grooves facilitate the export of metal chips, saving time and effort in drilling operation.

M2-6542 High Speed Steel

  • M2 high speed steel with 5% cobalt.
  • Provides an excellent combination of hardness, wear resistance, and toughness.
  • Adding cobalt can improve red hardness and heat resistance.

Wide Applications

Can drill clean and accurate holes in A3 steel, 45# carbon steel, cast iron, aluminum alloy, brass, wood and plastic, good for a variety of applications.

Suitable for handheld drills, drilling machines, bench drills, machining centers, CNC lathes. Use an appropriate lubricant (such as cutting fluid or oil) to reduce friction and heat build-up, especially important when drilling metal.

Notices

Make sure the drill bit is tightened securely into the chuck. Use a marker or hole punch to mark the exact location, this will help guide your drilling accuracy.

Start the drill at a slow speed and gradually increase to the desired drilling speed. Apply steady pressure to the drill, but avoid excessive force. Keep the drill perpendicular to the work surface to ensure straight and accurate holes.
