Discover the unmatched precision and reliability of RS PRO Dial Bore Gauges. Designed for professionals who demand the highest accuracy in internal diameter measurements, our dial bore gauges are the perfect solution for accurate measurements, providing highly accurate comparative readings of internal diameters, essential for quality control and precision engineering. During applications, this bore gauge can identify variations such as ovality and taper within the bore, ensuring comprehensive analysis and quality assurance.

The RS PRO dial bore gauge features a two-point measuring system designed for the precise comparative measurement of component hole sizes. In addition to measuring diameter, it can detect ovality and taper in bores. The spring-loaded centralising mechanism ensures measurements are taken across the true diameter of the component, enhancing accuracy and reliability.
