Chamfers are normally formed at a ____ degree angles

• A. 30
• B. 45
• C. 60
• D. 90

Answer: (B)

Chamfers are beveled edges created to remove a sharp corner and give a neat, protective transition between faces. They’re normally formed at a 45-degree angle because this angle provides a balanced slope that doesn’t overly weaken the edge while still making it easy to form, strip, finish, and protect during handling. A 90-degree angle would leave a square corner rather than a bevel, and 30- or 60-degree angles are less common for general edge chamfers in tilt-up work. So 45 degrees is the typical, practical choice.
