Inside Diameter Gauges

0 products

Inside diameter gauges are precision tools designed for measuring the internal diameters of holes or bores with high accuracy. Available in various types, including dial, digital, and non-reading models, these gauges utilize two- or three-point contact designs or measuring rods with anvils for direct or indirect measurements. Taper slot gauges feature a tapered metal body with side graduations for quick readings. Telescoping gauges adjust within bore holes, and their extended arms are measured with an outside micrometer upon removal. Small hole gauges are ideal for tight spaces, whereas large diameter gauges are specifically built for measuring extensive bore diameters directly.
