Question 197General Subjects - QMED

The correct answer is D) bronze stock using light pressure. When breaking in a new file, it is recommended to use bronze stock and apply light pressure. This is because bronze is a relatively soft metal that can be easily shaped and worked without damaging the file teeth. Using heavy pressure or harder metals like stainless steel or brass can cause the file teeth to become deformed or damaged, which can reduce the file's effectiveness and lifespan. The other options are incorrect because they either use the wrong material (monel, brass, or stainless steel) or apply too much pressure, which can lead to premature wear and tear on the file.
