🔍 SpeTool offers common angles like **20°**, **30°**, **60°**, **90°**, and sometimes others (such as 15° or 120°) in their V-groove/engraving bits. The choice of angle affects the line width and depth:\n- **20° or 30° V-bits**: Very acute, great for fine engraving, small text, and detail work. They create narrow lines without needing to go deep. Often have tiny tip diameters (like 0.1mm) for precision.\n- **60° V-bit**: A good all-around engraving bit. It can do reasonably fine text but also larger letters. Common for sign carving – it strikes a balance.\n- **90° V-bit**: Creates a wider groove for a given depth. Good for bold text, borders, or chamfering edges. Also faster to V-carve large areas because you don’t need as much depth to get a wide cut.\n- **120°** (if available): Very wide. Useful if you basically want a shallow decorative groove or big beveled edges.\nIn summary, use sharper angles (20/30) for very fine detail and use wider angles (60/90) for general lettering or if you want to clear more area. Many sign-makers start with a 60° for most work and use a 30° for small details inside letters, etc.
