🔍 Key Concepts

• Different types of punches used in metal work and their typical purposes • How force is applied to remove a tapered pin without damaging surrounding parts • Shape of the working end of each punch type and how it contacts the pin

💭 Think About

• Think about which punch is designed to push a pin all the way out, not just start a hole or mark a location • Consider which punch has a face that matches the end of a pin and can transmit force safely without slipping or deforming the pin • Ask yourself: which of these punches is commonly used AFTER the pin has already been loosened, and which is used specifically to drive pins out?

✅ Before You Answer

• Verify the primary use of each punch (drift, aligning, center, prick) in common shop practice • Check which punch has a blunt, flat or slightly convex end suitable for driving on a pin • Eliminate any punches whose main job is marking or locating rather than pushing or driving pins
