bit

1. the detachable piercing piece of a drill.

2. the metal part of the bridle that goes into the horse's mouth and over the tongue; used to restrain and direct the horse by exerting pressure on the attached reins. There are many patented designs, each with its devotees. The simplest is a plain bar but the common ones are jointed in the middle. The variations include side bars and curb chains which allow greater pressure to be put on the animal's jaw
