发明名称 Pencil sharpener bit
摘要 A pencil sharpener bit for use in sharpening pencils utilizing a portable electric drill, any motorized hand tool supporting the use of a chuck assembly or any hand held tool accepting tips with hexagonal ends is disclosed. The sharpener assembly rotates in a standard clockwise motion while the pencil is held by hand in a stationary position. The sharpener frame is of sufficient size to completely encase the point cutting assembly. The said point cutting assemble is set at a sufficient depth to remove successive layers of a pencil resulting in a conically shaped point. The sharpening assembly removes only enough material to bring the pencil to a sufficient point of sharpness. A slot is provided for material dispersal and collection in an outer cover. The housing of the sharpener is cylindrical in shape and is attached to a hexagonally shaped shaft bit intended for use with any standard chuck with three jaws or teeth.
