BORDO IMPACT Hex Shank Countersinks

  • Specifically engineered for use in impact drivers these bits are also fully compatible with conventional rotary drills.
  • 1/4″ hex shank facilitates fast tool loading in cordless impact drivers and quick change adaptors.
  • For countersinking and deburring in a wide range of materials including ferrous and non-ferrous metals.
  • The three fluted countersink is self centering with wide flutes and is used to provide a heavy chamfer in the entrance to a drilled hole.
  • This may be required to allow the correct seating for a countersunk head screw or to provide the lead in for a second machining operation such as tapping.
  • Use on medium to hard materials.
  • Resharpenable.
  • Manufactured from premium quality high speed steel for long service life.

    • Titanium Nitride (TiN) Coated Countersinks have a very hard gold coloured surface finish.
    • This coating is only a few microns thick and is achieved by Physical Vapour Deposition (PVD).
    • This treatment results in reduced friction, greater heat dissipation and reduced cold welding – which means higher speed and feed rates with greatly increased tool life.
    • As with all surface coated tools, performance will deteriorate after resharpening.
