1、IMPROVED ALIGNMENT: Our center finder is equipped with side locking screws to ensure accurate alignment between the ruler and the base. The use of flathead screws eliminates ruler offset caused by cone screws, resulting in accurate center lines. 2、VERSATILE FUNCTIONALITY: The center finder is designed to accurately and efficiently locate the center of both circular and square stock. It can also be used to draw 45 degree lines. By using the base as a positioning block and adjusting its position on the ruler, it can be transformed into a T square for drawing perpendicular and parallel lines on workpieces. 3、FINE CRAFTSMANSHIP: The base of the center finder is made of aluminum alloy, CNC machined, and anodized for enhanced durability, anti twisting properties, and corrosion resistance. 4、12IN RULER: The center finder comes with a removable 12 inch stainless steel ruler that features measurement systems in both metric and imperial units. Laser engraving ensures clear and durable markings, making the ruler suitable for standalone use. 5、ACCURATE CENTERING: The center finder draws two random lines that intersect at the center of a circle, providing accurate and reliable centering for various applications.
