Which number auger bit drills a 1/2 inch hole?

The correct choice for an auger bit that drills a 1/2 inch hole corresponds to the number 8. Auger bits are typically numbered in a way that their size corresponds to the width of the hole they can create, with lower numbers indicating larger bit sizes. For instance, a number 4 auger bit drills a larger hole than a number 8 auger bit. Therefore, the number 8, which corresponds to a 1/2 inch diameter, is perfect for making that specific hole size. Understanding the relationship between the numbering system and the drill bit size is crucial for selecting the correct bit for your drilling needs.
