  • Patent number: 5387059
    Abstract: A modified flute drill which prevents non-circular oval shaped drill holes which occur from incidental lateral or non-axial forces imparted by the operator is provided. The design modification is based on relieving, beveling, or dulling of the leading or side-cutting edge of the flutes of the drill bit for most of the length of the drill bit except for an initial specified length of the flutes where the leading edge of the flutes retains its sharpness and side-cutting capacity. The flute modification additionally imparts to the fluted drill a capacity of self-directional stability after the drill begins its penetration into the material being drilled, at the chosen initial angle of orientation of the drill bit, due to the absence of a side-cutting edge on the following major portion of the drill flutes.
