A V-block, also known as a V-block clamp or V-block fixture, is a tool used primarily in machine shops and laboratories for holding cylindrical objects securely during machining, measuring, or inspection processes. It typically has a V-shaped groove that allows round workpieces, such as shafts, rods, or tubes, to sit firmly in place, preventing them from rolling or shifting.
