Key Features to Look For
When buying metal drill bits, look at these things:
- Size Variety: Do you need many different sizes? Think about what you’ll drill. Get a set with a range of sizes.

Factors That Improve or Reduce Quality
Some things make drill bits better or worse:
- Sharpness: A sharp bit cuts cleanly. Dull bits make messy holes.
