The inserts Im using produce tight curls like a spring in this case about 1/4 inch dia but with 4140 its ductile enough that they don't break so the cuttings will keep going till they catch something and twist off. Some of the cuttings were 6 or 8 feet long.
Free advice is worth exactly what you payed for it.
