Product Description
The 84AZ-111-5J Dial Bore Gage is a fractional bore gage that offers three-point contact for tool alignment. This allows you to inspect bore and hole sizes without removing the workpiece. Made from aluminum, it is durable and lightweight. It uses jewel bearings for sensitivity, so you can get accurate measurements with ease. Set this gage with a master ring gage, gage blocks with parallel jaws, outside micrometer, or vernier caliper.
84AZ-111-5J includes a wooden case and (11) range extensions:
