17 views

To ensure a secure fit, the drill bit should be slightly smaller than the anchor. Typically, the drill bit should be 1/64 to 1/16 inch smaller than the anchor itself. This allows for a snug fit and better grip, ensuring your anchor holds firmly in place.

FAQs & Answers

  1. What happens if the drill bit is too large for the anchor? A drill bit that is too large can cause the anchor to fit loosely, leading to a weak hold that may fail under weight.
  2. Can I use the same drill bit size for different types of anchors? It’s best to consult the anchor's packaging for specific size recommendations, as different anchors may require different size adjustments.
