Compression Torsion Fatigue Testing of Drill Bit Tips

The challenge

In operation, drill bit tips are subjected to cyclic loads and amplitude vibrations. Such fluctuating load profiles induce cyclic stresses that often result in castrophic fatigue failure.

To ensure that drill bit tips are suitable for purpose and predict the expected service life, the components must be tested under worst-case combined compression and torsional loads.
