Starrett One-rev Dial Calipers for Flawless and Quick Readings. Starrett offers a versatile set of one-rev dial calipers for measuring outside, inside, and depth dimensions at the rate of thousandths of an inch over a full revolution. The models come in both inch and metric graduations. The dial faces of these dial slide calipers are offered in white, red, black, and yellow colors with contrast markings on them, while the main scale is given a satin finish with sharp black graduations on it. So, you can easily read clear graduations on both. For performing inside and outside measurements, knife-edge contacts are provided with the calipers. For depth measurements, some models come with a depth rod, and for others, a depth base attachment is offered. The thumb roll helps you easily make fine adjustments with just one hand. The rack, measuring surfaces, depth rod, and gears are all made of hardened stainless steel, which adds up to their tool life and consistent performance and precision. A bezel screw is provided for zero adjusting the dial and a lock screw for locking the sliding jaw in place. The positive split gear allows the calipers to have anti-backlash control. The devices also offer direct readings, reliability, and high accuracy, and they are easy to handle as well. Hence, these are considered the best-choice dial calipers by mechanics and toolmakers. Starrett's dial calipers ensure quick and accurate measurements. They are the everyday tool for engineers, machinists, scientists, mechanics, and technicians used in manufacturing, inspecting, analyzing, and reverse engineering applications. They are the preferred tool in industries such as automotive, construction, machining, science labs, etc. Moreover, Starrett supplies these dial calipers in a well-molded durable plastic/wooden case.
