Standard Gage dial bore gages were manufactured in Poughkeepsie, New York until 2002. They made several different bore gage configurations at that time (perpendicular and vertical for example). Only the regular model (shown below) and the 90° right-angle model are still available (see page 114). The newest models of Standard Gage dial bore gages are manufactured in Switzerland and Germany by Tesa who owns the rights to the brand name. Tesa is the manufacturer of high-end Etalon, Compac and Interapid gages. Surprisingly, the indicator movement is now supplied by Käfer in Germany. We are pleased to report that these are a substantial improvement over the old style. As an alternative, you may wish to purchase the Standard-style bore gage made in USA. These have identical measuring heads but the dial indicator will carry the name Dorsey (see below). In all other respects, these bore gages are the same as the old Made-in-Poughkeepsie models. - A new introduction is the rinsable bore gage.
- Digital versions are also available with the option of converting your dial bore gage into a digital electronic gage.
- See our page 8 for a comparison with other brands of dial bore gages.
- Metric dial bore gages are also available.
- Optional carbide, nylon and diamond contacts are now available. See parts on page 72.
In order to keep prices down, most of these gages ship in a simple styrofoam box. However, sturdy wood storage boxes are available for special orders such as bore gages with long depth extensions and for the combi-kits. Wood boxes can also be purchased as an option (see bottom of this page). 
Made-in-USA Dorsey Standard Bore Gage model 3 is shown above. Note that many of our Standard Bore Gages feature extended ranges, beyond those offered in regular catalogs. The Centralizing Plungers automatically locate the gaging contacts on the bore diameter even when the gage is inserted at an angle. Standard Gage dial indicator graduations are .0001" or 0.002 mm and each model comes complete with all range extensions and adapters. The gaging depth shown is the maximum depth without depth extensions (available separately). Setting rings are not included, nor are they required. Standard style bore gages are offered with the Dorsey dial indicator at substantial savings. Dorsey Standard bore gages have dials with convenient revolution counters. These versions are made in USA and are designated with the prefix DS or DBL in the price chart below. Don't hesitate to order these, since they're every bit as good, they're more likely to be in stock and they're home grown. Repair service and parts are no problem. 
Small sized Dorsey DBL bore gages are not an exact replica of the old Standard No.0 and No.1 bore gages but they are a very suitable replacement for the discontinued models. DBL-499-C is shown above. 
Detail of made-in-USA model DBL-499-C (.499" to 1.0" range) The two DBL models shown here come in a handsome wooden storage case with all necessary contacts and extensions. They do not come with wrenches since the manufacturer considers them unnecessary. The manufacturer advises that contacts should be hand tightened only. All bore gages size 2 through 6 come standard with steel contacts. The gaging contacts and/or the centralizing contacts are also available in carbide, Delron® nylon or diamond in some cases. DBL bore gages with the suffix -C come with carbide contacts. (Diamond contacts are not available for the two small DBL bore gages.) Other gaging depths up to 144" are available for most models. A word of caution though: it can take anywhere from 2 weeks to 4 weeks if you're ordering special length extensions. Plan ahead.
