BORDO IMPACT Hex Shank Countersinks

Specifically engineered for use in impact drivers these bits are also fully compatible with conventional rotary drills.
1/4″ hex shank facilitates fast tool loading in cordless impact drivers and quick change adaptors.
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.
Manufactured from premium quality high speed steel for long service life.
