BORDO HSS Co5 TiN Coated Single Flute 90° 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.

BORDO HSS Co5 Bright Triple Flute 90° Countersink

Triple flute countersinks are ideal 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.
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.

cutting edges for longer tool life.
Cemented carbide insert is an alloy of Tungsten Carbide (WC) and Cobalt (Co).
B100 is a unique rare metal grade with great heat and cracking resistance.
TiAlN PVD coated – suitable for applications with low to intermediate cutting speed.
PVD coated grades are recommended for applications with low feed rate where high edge toughness is required.
