You'll get dust if you core dry blanks. Coring dry hardwoods takes a long time and is very little fun, IMHO. It involves more tip sharpening than actual coring and I rarely do it. On the other hand, coring green wood can be both fun and fairly quick. It won't produce dust. I usually get something like wet mush coming out and it's easily dealt with. The wet cuttings just pile up on the bed ways and I use a free hand to scoop and toss in the trash can without any interruption in coring. That's my two cents.
