Cuts well in various sizes and does well. Runs clean, no scratches. My only concern is that it takes some time and patience to adjust the bit to the exact size you want to cut. You either press the bit and it doesn't move, or you press it and it moves 1/8 inch. It's hard to find a happy medium with a turnbuckle and thread combination. Trial cut, readjustment, trial cut, breakage, post-processing.
