InSize Dial Bore Gage

The InSize Dial Bore Gage (also called a dial bore gauge or cylinder bore gage) is a mechanical inside-diameter measuring tool. Machinists, engine builders and auto mechanics use it to check bore size, taper and out-of-round condition. It works on engine cylinders, bearing bores, bushings and other machined holes.

Key Features:

• Dial indicator with 0.0005" graduations, so small differences in bore diameter are easy to read
• Steel moving tip and ceramic fixed anvil for wear resistance and repeatable contact
• Mechanical operation with no battery needed
• Dial indicator included, so it is ready to use once set to size
• Supplied in a fitted storage case that protects the gage between uses
• Part of the InSize 2323 series, which covers a range of bore sizes

To use it, set the gage to a known size with a micrometer or setting ring. Then rock it in the bore and read the deviation on the dial. The InSize Dial Bore Gage is a precise, repeatable choice for shop and inspection work.
