Which feature on stock is a chamfer?

• A. Chamfer
• B. Fillet
• C. Groove
• D. Radius

Answer: (A)

A chamfer is a straight-edged bevel cut along the edge of stock to remove a sharp corner. It creates a flat, angled surface—usually about 45 degrees—so parts can fit together more easily and burrs are reduced. This differs from a fillet, which is a rounded corner or transition rather than a flat bevel. A groove is a channel cut into the surface, not an angled edge. A radius is a curved arc forming a rounded corner, not a flat bevel. So the edge feature that defines a chamfer is the flat, angled bevel along the edge itself, which is why this option fits the term best.
