Pigtail Scratches
The curlicue scratches sometimes caused by handheld electric sanders; sometimes called swirling
Pilot Bearing
A bearing mounted on a bit that guides the bit during a cut

Extremely useful type of fixing. An elliptical slot bored at an angle in the face of a board, through which a screw is driven to secure that board to an adjacent piece of wood; sometimes called screw pocket. popular alternative to doweled, mortise & tenon or other joining techniques. A jig creates a pocket hole with a special step bit that leaves a pilot hole as well as a shoulder for stopping the pocket screw at a pre-determined depth.
