Mitutoyo 511-702 Bore Gauge Without Indicator, 35-60mm

Introduction Mitutoyo 511-702 Bore Gauge without indicator, 35-60mm

The Mitutoyo 511-702 Bore Gauge without indicator features interchangeable anvils and optional accessories for close tolerance inside diameter measurements. It offers durability with its carbide-tipped points and a measuring range of 35 to 60 mm.

The grip reduces the influence of heat from the operator’s hand during use to retain high-accuracy measurement. This gauge uses a two-point contact system for the detection of geometry problems such as ovality and taper, and carbide-tipped contact points provide extended wear and improved abrasion resistance. This gauge is for use with Mitutoyo dial indicators (sold separately).

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.
