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.
