About Single Flute Countersink

• For countersinking and deburring in a wide range of materials including ferrous and non-ferrous metals.
• The fluted countersink cutter 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 light to medium materials. Resharpenable.
• 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-colored 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 surfaces, coated tool's performance will deteriorate after resharpening.
