Description
About this item:
- 20mm 90 Degree HSS Co5 TiN Coated Single Flute Countersink
- Single flute countersinks are ideal 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.
- M35 Cobalt High Speed Steel 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.
