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.

Spiral flutes enable easier tool penetration.
Titanium Aluminium Nitride (TiAlN) is a thin film coating that was developed from Titanium Nitride.
TiAlN offers higher temperature resistance than TiN, as well as slightly higher hardness and especially higher hot hardness (i.e. the hardness at high temperatures).
It is primarily used in high temperature environments above the limits of TiN usage.
This coating works by forming a thin surface layer of Alumina (Al2O3), or Aluminium Oxide ceramic.
As the layer wears it continuously reforms.
