Question 1 of 27070

Q

To finish tapping a blind hole, it is best to use a __________.

🔍 Key Concepts

• Difference between taper, plug, and bottoming taps • How much of the tap is fully threaded versus tapered • What a blind hole is compared to a through hole

💭 Think About

• Think about what happens at the bottom of a blind hole—can a long tapered section cut full threads all the way down? • Which type of tap has cutting threads almost to its very end, allowing threads to be formed close to the bottom? • Which tap is usually used first to start threads easily, and which is used last to finish them in tight spaces?

✅ Before You Answer

• Identify which tap type has very little taper and nearly full-depth threads to the tip • Confirm which tap is typically used to start a hole versus to finish near the bottom • Make sure the tap you choose can cut threads as close as possible to the bottom of a blind hole without relying on a long lead taper
