  • Patent number: 4338050
    Abstract: A method and tool for drilling holes in a composite of materials having different strength and elastic characteristics. The tool has a planar end surface inclined in two directions relative to the tool axes, and an axially-extending flute which define, with the periphery of the tool, a cutting single end point and adjacent cutting edges which are guided within the hole being formed by three axially-extending wearstrip segments of the tool periphery. The radius of the tool is gradually reduced from the final wearstrip to the side of the flute opposite the cutting single end point. The cutting end portion of the tool may be formed of a very hard carbide material. The method provides for simultaneous point and surface cutting of the composite. Point and surface cutting occur at the outer circumferential surface of the hole generally along a radius of the hole to be drilled. Cutting also occurs along a radius of the hole being generated.
