🔍 Key Concepts

• Types of hand taps used for cutting internal threads (taper, plug, bottoming) • How chip load and ease of starting differ between tap shapes • When a hole goes all the way through versus a blind (bottomed) hole

💭 Think About

• Think about which tap shape is best for starting a thread easily in a through‑hole and can also be used to carry the thread all the way through. • Consider which taps are specialized for finishing near the bottom of a blind hole rather than general through‑hole work. • Ask yourself: if the tap can go completely through the material, which style gives a smooth start and adequate chip clearance from entry to exit?

✅ Before You Answer

• Verify which tap has the longest lead-in (gradual taper) on the cutting threads. • Check which tap is specifically intended for blind/bottomed holes rather than through-holes. • Confirm that the correct choice is commonly recommended as the first tap used when cutting a new thread in a through‑hole.
