• 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.
  • All Bordo Countersinks are made from 100% M35 Cobalt High Speed Steel.
  • Cobalt offers increased wear and heat resistance in alloy steels, stainless steels and other abrasive or difficult materials. This increases tool life in all production applications.
  • 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.
