Surface Grinding Wheel: 7" Dia, 1/2" Thick, 1-1/4" Hole, 46 Grit, H Hardness MPN:34615

Class XX master ring gages used for inspecting wire diameter falls under the ASME B89.1.6 standards making them essential tools for quality control ensuring consistency during manufacturing of precision metal components. With a wire size number 4 featuring an inner diameter of 0.254 mm providing an accurate reference point, it caters to industries such as medical devices or electronics where close tolerances need to be met reducing scrap rates resulting from off-tolerance components improving yields while saving costs associated with repairs, making them ideal for job shops offering gauging services, and calibration labs performing audits.
