  • Patent number: 8622663
    Abstract: A drill bit having features rendering it particularly effective in cutting holes in carboresin laminates of the type used in the aircraft industry. A pair of diametrically opposite lands slope radially inward at the working end of the bit to a pair of cutting edges disposed at an obtuse angle to one another and forming an efficient cutting tip. Notches with sloping ramps adjacent the cutting edges efficiently convey cut material to adjacent flutes. The lands curve radially inward between their full diameter portion and their cutting tips and the junction of the curved portion and the constant diameter portion of the lands is machined to provide a more gradual transition.
    Type: Grant
