  • Thread cutting bit
    Patent number: 6293738
    Abstract: A screwing plate or thread cutting bit comprising at least one cutting tip whose contour matches the desired shape of the threading. The cutting tip is configured as a chip forming element which is shaped in the form of a spur located between both sides of the cutting faces. The chip forming element rises above the cutting faces more or less in the form of a table mountain. The flanks of the spur, which are slanted in the form of inclined walls, are spaced at different distances from the adjacent cutting edges so as to form cutting faces with differing widths.
