DISCUSSION:

  • Note that the nearly non-spiraled sections along the working length provide an area that can become more easily spiraled when rotational torsion is applied. The result is relatively high rotation to failure but added no significant increase in peak torque. It is also important to remember that 3 rotations, once bound, only requires 0.6 seconds to fail while rotating at 300 rpm.
