- General purpose geometry for drilling in a wide range of operating conditions and materials
- Taper length provides longer overall length and flute length for deeper drilling
- Peck cycles may be appropriate for deep hole drilling
- Black oxide finish provides increased wear resistance and added lubricity
- High speed steel (HSS) provides good wear resistance and can be used in general purpose applications on both ferrous and non-ferrous materials
- Oxide prevents chip building, galling and welding on the workpiece
- Spiral flutes are constructed with a higher flute angle to remove chips more easily
