CH4D makes the die and it isnt expensive, under $50 if I remember, but you might need to machine off some of the toolhead to allow the chips to be sucked away.
I milled about .350 off my 1050 toolhead to make it work.
You will have to machine a tool head for the hose attatchment to work. If you don't already have a RT1200, the Rapid Trim for 7.62x39 has a longer trimmer shaft and die and will work on unmodified toolhead. I beleive the 7.62x39 trim die needs to be shortened al little to trim brass to right length.
