🔍 Key Concepts

• Cutting speed and how it affects heat at the drill tip • Where wear appears on a drill when it is overheated versus when it is incorrectly ground • Difference between clearance angle and margin width on a drill bit

💭 Think About

• Ask yourself: what condition would cause the very outer corners of the cutting edges to overheat and wear fastest? • Think about how increasing or decreasing cutting speed changes temperature at the cutting edge. • Consider whether clearance angle or margin width would mainly affect side rubbing, center wear, or outer-corner wear.

✅ Before You Answer

• Identify which choice is most directly tied to heat buildup at the cutting lips, especially at the outer edges. • Eliminate any options that mainly affect guidance and stability of the drill rather than tip temperature. • Make sure your choice explains why the wear is on the extreme outer corners, not near the center or along the margins.
