Terms of the Trade: What Is a Miter?
A miter is any angled cut on a piece of wood, the most common being 45 degrees so it can connect with another piece. The cuts are usually across the edge or the face of the lumber. Face mitering can be seen in photo frames and molding, while edge miters are seen in cabinet corner joints and similar box construction. Because most miters are on the end grain of a piece of wood, adhesive doesn't hold well when connecting to another piece. To counteract that, nails and dowels are often used.
