Q

Tapping threads into a blind hole should be finished by using a __________.

🔍 Key Concepts

• Difference between taper, plug, and bottoming taps • How much of the thread each type of tap can cut close to the bottom of a hole • What a blind hole is vs. a through‑hole

💭 Think About

• First, picture what makes a blind hole different from a through‑hole. Why does it matter if the tap can exit the other side or not? • Think about the shape and length of the chamfer (the tapered cutting portion) on each tap type. Which one is designed to cut threads very close to the bottom? • Which tap type is normally used to start threads, and which is used to finish them in a hole that doesn’t go all the way through?

✅ Before You Answer

• Be clear on the definition of a blind hole (does it pass all the way through the material?). • Match each tap type to its purpose: starting, general through-holes, and finishing near the bottom of a blind hole. • Visualize or sketch the tip profile of each tap and check which one leaves the least unthreaded depth at the bottom.
