🔍 Key Concepts

• Tools used to finish or slightly enlarge an existing drilled hole • Difference between cutting a brand‑new hole vs. smoothing an existing one • Common machinist/metalworking terms for precision hole finishing

💭 Think About

• Which of these tools is specifically meant to refine the size and smoothness of a hole that already exists, rather than create a new one? • Think about which items in the list sound like general descriptions and which sound like the name of a specific precision tool. • In metalwork or fitting, what specialized tool is used after drilling to bring a hole to exact size with a smooth finish?

✅ Before You Answer

• Identify which choice is a named precision tool, commonly found in machinist or fitter toolkits. • Eliminate any choice that mainly describes creating holes, not refining them. • Ask yourself which tool a mechanic or machinist would use to bring a bolt hole to an exact diameter after drilling.
