Description

The Starrett 275-6 Toolmakers’ spring-type outside calliper opens to 6” (152 mm) with a fine adjustment and balance. It is precision made to rigid standards, for easily reproducible and accurate transfer of measurements of the internal size of an object. This calliper has round, inwardly curving legs for outside measurements and comes with a solid nut. The hardened fulcrum stud is strong to help prevent give or play in the measurement, ensuring better accuracy. The large leg bearing surfaces prevent side deflection, again to aid in accuracy. The strong, flexible bow spring has a sensitive touch. The centrally located adjustment rod ensures smooth action when opening and closing the calliper. Callipers measure the distance between two opposing sides of an object. They make inside, outside, depth or step measurements, according to their type. Callipers are commonly used in architecture, metalworking, mechanical engineering, machining, manufacturing, carpentry and medicine. The simplest callipers have two legs to mark the two points and require a ruler to take the measurement. More complex callipers use two sets of jaws instead of legs and have up to two graduated scales. Vernier, dial and digital callipers give direct and accurate readings and are functionally identical, having a calibrated scale with a fixed jaw and another jaw with a movable pointer that slides along the scale. The Vernier calliper has a scale sliding parallel to the main scale for an additional, fractional reading to improve measurement precision. The dial calliper has a circular dial with a pointer on a toothed gear rack replacing the second Vernier scale
