Deep-hole drill with high heat resistance to drill non alloyed and alloyed steels as well as long chipping materials with tensile strength up to 1.300 N/mm2. The special point design with web thinning form S optimises chip breaking and reduced feed force and torque. Capable of drilling through drill bushings. Ample chip space enables drilling over five times diameter deep without pecking. Tin coating provides longer tool life or increased cutting speeds.

- Cobalt high speed steel (hsco) cobalt steel is a variation of high speed steel with a higher content of cobalt, it has a high red hardness that gives it much higher heat resistance, this allows tools made of cobalt to be run at faster speeds and higher feed rates
- Titanium coated surface gives a very high surface hardness to help penetrate tough materials, it’s highly corrosion resistant and significantly reduces friction between bit and work piece
- 135 Degree split point angle reduces the amount of pressure needed to make the drill cut, the split point is also self centring which means the drill starts cutting exactly where is comes into contact with the material
- Ground flutes provide fast chip removal to maximize accuracy and efficiency
- For use on machines or hand held applications
