Reversible cylindrical plug gages, sometimes referred to as reversible plain plug gages are used to check a drilled hole. The reversible gage features that when one end becomes worn or damaged, the gage member can be reversed providing exceptional value, essentially two gage members for the price of one.
The diameters are ring lapped to size and hand polished providing for superior accuracy and ensuring maximum gage wearability. Available with GO and NOGO members in Class XXX, XX, X, Y and Z compliant to ANSI specifications. Aluminum gage bodies anodized green for GO and red for NO GO provide quick positive identification. The gagemaker’s tolerances will be applied plus on the GO member and minus on the NO GO member unless otherwise specified.
Available in steel, chrome and carbide. Steel gages are made of high quality 52100 tool steel hardened to Rockwell C60-64 and cold stabilized to minimum size and form variations providing exceptionally long life of the gage. Gages are 2.0” in length. Special length gages are available up to 6.0” length. All gages are ground lapped to a 5 micro inch surface finish or better. Cylindrical steel and chrome reversible plug gages are available from .015” – 1.0100”. Carbide plug gages are available from .040” - .761”.
Special features such as depth notches, air flats, pilots, radius, and chamfers are priced on request. WESTport Gage provides a Certificate of Accuracy, traceable to NIST (National Institute of Standards and Technology), free of charge with every gage.
