Stan, I have not. But a high speed steel reamer will get trashed cutting it. A sharp HSS reamer that has been TiN coated should cut it. TiN is harder than chrome.

My 3" forcing cone reamer is simply a regular #8, 1/4" per ft taper pin reamer, with the forward chamber diameter O.D. ground (no clearance) on it. Something like this.

A custom cutter grinder should have a source ti TiN coat. Carbide would just be expensive as hell.
