In the photo...I can see all sorts of ways to install the bit...
There are markings on the thing..now is that only on that face of it...or is there similar markings on the opposite side? Does the markings go facing the camera...facing away from the camera....or same choices but rotated so the markings are on the underside and then same questions.....
Now if I was educated and had learned to work with my brains like an engineer instead of with my hands like a pilot....I would know that answer. Right?
