Drill bit should have the following characteristics:

1. Meet the hardness. It is necessary that the hardness of the drill bit be greater than that of the workpiece being machined.

2. Intensity and patience of contentment. Because the drill bit is subjected to great torsional and axial forces while machining the workpiece, it is necessary to have satisfactory strength and endurance.

3. Meet the wear resistance. Because the processing data tolerance is good, the demand for cutting blade to meet the sharp, so the data is necessary to meet the anti-wear ability, so as to reduce hardening.
