Patent abstract
An improved vacuum drilling system and drill bit includes a generally hollow vacuum drill bit with one or more chip inlets arranged proximate to one or more cutting surfaces. The drill bit also includes grooves along its exterior. When the drill bit is guided by a bushing or guide hole, the grooves serve to reduce the friction therebetween. The grooves can also convey air for cooling and improved chip collection.
