For installing a concrete anchor, using a hammer drill to make the hole is standard practice.

• A. It depends
• B. Not specified
• C. True
• D. False

Answer: (C)

When you install a concrete anchor, preparing a hole that fits the anchor precisely is essential. A hammer drill combines rotation with percussive impact, which helps the masonry bit cut through concrete efficiently and produce a clean, round hole to the correct diameter and depth. That correct hole size and depth are key for the anchor to seat properly and develop its full holding power. Using a regular drill without hammer action can result in slower drilling, rough or undersized holes, and poorer anchor performance. So, using a hammer drill to drill the hole is standard practice.
