I'm guessing that is what leaves the somewhat 'mosaic' pattern in the finish as the chip breaks as opposed to the full circumference lines?

Another question: Isn't the goal to get short chips from any material when possible? Or not?

I realize that is probably impossible in some cases, but thinking back - I don't recall anyone ever recommending to TRY and cut long stringy chips in any material. Or have tool geometries progressed enough to eliminate them all together if you have the right insert/chip breaker?
