Our software also has several automatic ways of addressing piercing, so it is a case of selecting which one you want to use and when. Generally once you have selected a pierce procedure, you may want to keep it for similar kinds of materials, like all brittle and fragile materials would have one setting - (stone, glass, laminates, composites, marble, acrylic etc) where harder non brittle materials may have another setting - (steel, aluminum, stainless etc.)</span></p>
