What Are Dial Bore Gages?

Dial bore gages are specialized tools used to measure the acute diameter of a machined hole in order to achieve an exact bore size reading. Capable at measuring as little as .00025 of a centimeter, dial bore gages provide precise results to maximize honing success.

Sunnen Dial Bore Gages are fast, easy and accurate. All Sunnen Dial Bore Gages read out 0,002 mm (.0001 inch) and feature all-carbide gaging points, wear-proof ball crank, and adjustable centralizers. Each gage comes packed in its own sturdy box with all tools and wrenches required for setup and adjustment.
