In the collection of bits that came with my 1964 Deckel FP2 was this too. It was crammed in with single-point cutters for a Wohlhaupter and random lathe tools. What is it? Is it a boring bar or for cutting internal threads on a lathe? The body diameter (22mm) is too big for my UPA3.
There are also a handful of new inserts, which have a small carbide cutter brazed onto a steel support. There are a series of tick-marks to indicate rotation (which sets the depth of the cutter) but the cutter itself has a fixed orientation.
