A: Yes, they do make drill bits that have the threads running the "wrong" direction, which makes them left handed. They were used primarily before CNC machines.
One important use is when a screw head is damaged and cannot be removed using the normal tools. By drilling out the screw with a left-handed bit, the rotation will tend to unscrew the normal, right-handed screw. That can be very helpful indeed.

Q: We have a gang rip saw that we have trouble with. When the lumber is about halfway through, the piece travels away from the fence. The infeed has rollers that are at an angle so that the lumber is pushed against the fence. That seems to work well for the beginning of the pieces, but then it moves away from the fence. When we increase the feed roll pressure it seems like it might get worse. Any ideas?
Getting the most from a widebelt sander and abrasives is a matter of balancing your budget with proper features to perform the work needed.

Q: What is ring shake? How do we detect it in our oak lumber? Does this shake cause a bad odor or other manufacturing problems?
