Fowler 52-646-400-0 , Extender Dial Bore Gage Kit with 1.4-6" Measuring Range
The Fowler 54-646-400 X-tender Dial Bore Gauge Set has a measurement range of 1.4 to 6" and gradient spacing is 0.0005"/.001mm. A two-point contact system is used to detect geometry problems such as ovality and taper, and carbide-tipped contact points provide extended wear and improved abrasion resistance. The gauge is self-centering and includes an extension holder. This product has 1 year warranty offered by Fowler High Precision. If you experience any problem contact Fowler directly for warranty claims.
Bore gauges measure holes, or bores, in a workpiece. They can measure the interior diameter of a hole at any depth, while internal micrometers can only measure to the depth of their teeth. Bore gauges are typically calibrated with a setting ring and come in two types: simple and direct-measuring. Simple bore gauges are used with a caliper to transfer the hole measurement, while the more complex gauges take the measurement directly, and display it through a vernier, dial, or digital display. Bore gauges have a two- or three-point contact, indicating how many points on the gauge head touch the inside of the bore. Two-point contacts are better at measuring ovality, while three-point contacts are used to measure lobing or triangular form error. Pistol-grip bore gauges are used for fast, single-handed operation with repeatable results from one operator to another. Bore gauges can also be used in special applications, such as measuring threads, spline pitch diameters, and deep bores.
