If you buy the Lyman hand held VLD inside debur tool, just unscrew it from the handle and it will screw right on to the post on the RCBS prep center. I agree the ones that come with it stink, I can usually get about 1000-1500 pieces across it before it dulls. The Lyman has been going for well over 25K and no real signs of any significant wear. RCBS claims 10K on theirs but if that is the case they are having to bear down with a lot of weight to get there.
