Starrett 66568 Dial Caliper 6 in 0.001 in Stainless Steel

Product Description

The STARRETT 66568 is a stainless steel dial caliper designed for precision measurement in trade and industrial applications. It covers a 6-inch measurement range with 0.001-inch graduation and 0.001-inch accuracy, making it suitable for close-tolerance work. The dial face is white with a black case and a satin chrome finish for glare reduction and durability. The 1.5-inch jaw length accommodates a wide variety of workpiece geometries. This caliper performs outside, inside, and depth measurements from a single tool, reducing the number of instruments a technician needs on hand. It ships with a protective case.

The STARRETT 66568 suits machinists, HVAC technicians, plumbers, and pipefitters who need reliable dimensional verification during fabrication, installation, or inspection work. It is equally appropriate for shop bench use and field service. The 0.1-inch-per-revolution dial movement and clearly graduated beam allow fast, repeatable readings without the need for a digital display or battery. Applications include checking pipe OD, fitting clearances, tubing wall thickness, and component stock dimensions.
