Abstract
The inside diameter and outside diameter of an upset pipe end are simultaneously bored and turned respectively by a combination tool. Boring and cutting elements on the tool are simultaneously disengaged from the pipe end in a controlled manner to taper out the cuts and permit rapid retraction of the tool without contacting the finished surfaces and possibly producing a scratch mark.
