We are using a hole saw to cut into pipe. Because of the variety of steel pipe material we cut, the chip size and shape differ quite a bit. Sometimes we just get small flakes when other time we have this "ball" of steel wool-like product. I need to consistently produce flakes while minimizing the wad of stringers. I read the PVC question and answer about retracting during cutting. I don't think that is an option. I believe I would be loading the cutter's teeth too severely. Plus, my machine is auto feed. One cutting speed, one feed rate. Is there a theory I can investigate concerning the staggering of teeth, altering the tooth heigth, increasing the positive rake, that will help produce the small, light chips?
Thanks for the help.
