20mm 90 Degree HSS Co5 TiN Coated Single Flute Countersink

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.
