Ok that's a;; good answers to your question.I can sum it up in a few works. I always use olson's blades. have tried FW 's but olsons blades last longer and in my opinion they are the best. just my opinion I very seldom run over 1/2 speed. Don't feed too fast. I use #3,#5,#7, and for thick wood ( 1 1/2) for fretwork it's a #3 & #5 blade
