🔍 Key Concepts

• Machining sequence: what tool is used AFTER drilling to bring a hole to precise size and smooth finish • Difference between drilling, reaming, and broaching operations • Which tools are mainly for starting a hole vs. finishing a hole

💭 Think About

• Think about which operation is normally done first: rough creation of the hole, or precision sizing and smoothing • Ask yourself: which of these tools is typically used to slightly enlarge and smooth an already-drilled hole, not to start it? • Consider which option is mainly used for cutting keyways or complex internal shapes, rather than simply sizing a round hole

✅ Before You Answer

• Identify which tool is specifically designed to finish a drilled hole to an accurate diameter with a smooth surface • Eliminate any tool whose primary purpose is to start a hole rather than finish it • Eliminate any tool used primarily for non-round or complex internal shapes, not just accurate round holes
