Question 1 of 27070

If the drill point lips are of unequal length, the drill will wobble and __________.

🔍 Key Concepts

• Effect of unequal drill lips on how the bit centers itself in the hole • Relationship between lip length and hole size/shape • How wobbling changes the path the drill point follows in the workpiece

💭 Think About

• Think about what happens to the center of the drill if one lip is longer than the other—does it stay on center or move in a small circle? • If the drill is wobbling in the hole, will it tend to remove more metal, less metal, or the same amount as a properly ground bit? • Which choice best matches the result of the drill point not being centered in the hole?

✅ Before You Answer

• Focus on what wobbling physically does to the size and shape of the hole, not just to the drill temperature or chip shape. • Check which option most directly results from the center of rotation shifting off-center. • Eliminate any choices that could also happen with a correctly ground drill under heavy load—look for the effect that is specific to unequal lip length.
