Are of general purpose flute design but all sizes have a 1/2 by 2-1/4 long shank.  The maximum overall length is 6 and the flute length is 3.  This makes them short drills in the larger sizes and thus well suited to use in portable electric drills equipped with 1/2 chucks.  They are highly effective in tough, high tensile strength materials.  The 135 degree split point reduces thrust and eliminates walking at the drill point.
