摘要： An improved boring tool with a hollow boring bar and has an exterior semicircular surface and an opposite eliptical surface over a substantial portion of its length and has a circular slotted end portion, the diameter of which is sufficiently small to pass through the neck opening in the workpiece whose interior is to be machined, a piston having its rod extending through the boring bar and connecting to a linkage which also connects to a tool holder which is pivotally mounted to the enlarged slotted end of the boring bar so that the tool holder may be pivoted to position the tool secured to the tool holder for the boring of the arcuate interior surface immediately inside the neck of the workpiece responsive to axial and radial movement of the boring bar in the opening of the neck.
