Q

The size of a drill is usually marked on the __________.

🔍 Key Concepts

• Basic parts of a twist drill (point, shank, flute, body, tang) • Where manufacturers typically put size markings on small metal tools for visibility and to avoid wear • How a drill is held in a drill chuck or drill press

💭 Think About

• Think about which part of the drill remains exposed and easy to read when the drill is mounted in a chuck or drill press. • Consider which surfaces are most likely to get worn, ground, or cut during drilling and sharpening, and therefore are NOT ideal for permanent markings. • Visualize an actual drill bit you’ve used: where do you remember seeing stamped or engraved numbers?

✅ Before You Answer

• Be sure you can name and locate each part of a drill: point, flute, shank, and any taper. • Ask yourself which part is usually gripped by the chuck versus which part is doing the cutting. • Check which surface is typically smooth enough and large enough to clearly stamp or engrave size information.
