With the Carat centring pin, you start every diamond core drilling task with complete control and pinpoint precision. This 60mm centring pin with a 5/4"UNC connection prevents the diamond core bit from wandering or slipping on hard surfaces like concrete and masonry. By securing a stable center point from the very first rotation, you eliminate surface damage, minimize tool vibration, and prevent uneven segment wear during handheld drilling. Engineered for a direct and secure fit, it mounts seamlessly onto compatible Carat core drill machines such as the A-2225 and A-3025, ensuring dependable and accurate drilling performance.
