Toughened (or tempered) glass cannot be cut, drilled, or altered once it has been manufactured. This is because the toughening process involves heating the glass to high temperatures and then rapidly cooling it, which locks in internal stresses. Attempting to cut or modify it after this process will cause the glass to shatter.
