Description

The Fowler 54-646-500-0 X-tender Dial Bore Gage Set has a measurement range of 1.4 to 6" and indicator graduation is 0.0001". 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 gage is self-centering and includes a 2 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 gages measure holes, or bores, in a workpiece. They can measure the interior diameter of a hole at various depths, while internal micrometers can only measure to the depth of their contact surfaces. Bore gages 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 gages take the measurement directly, and display it through a vernier, dial, or digital display. Bore gages have a two- or three-point contact, indicating how many points on the gage 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 gages are used for fast, single-handed operation with repeatable results from one operator to another. Bore gages can also be used in special applications, such as measuring threads, spline pitch diameters, and deep bores. Fowler, an American company, manufactures inspection and measurement instruments such as electronic indicators, calipers, bore gages, and digital scales. The company, founded in 1946, is headquartered in Newton, MA.
