SALES: Sizes 2 through 6 are American made dial bore gages, made by Dorsey in New York. They are identical to the old Standard Gage bore gages made in Poughkeepsie except that the dial indicator has been replaced by the better quality Dorsey indicator. All other parts are interchangeable. This is a rugged and reliable tool. Bore gage sizes 0 and 1 are made in Europe using a Kafer dial indicator and the measuring head is also identical to the old Standard Bore gages made in New York.
The 90 degree dial bore gage (Style 2) makes reading the dial easier. Specifically designed for jig-grinding machine operations. You won't have to disturb the machine tool setup and you won't have to crane your neck or crouch into dangerous positions. You may find it hard to "rock" the gage into place until you get used to it. Maneuvering with a right angle does not come intuitively.
In order to keep prices down, these bore gages ship in a simple styrofoam box. However, sturdy wood storage boxes are separately available.
Model B1-22103 made in USA (shown above). Except for the new-and-improved dial indicator, all other parts are identical to the old Standard Gage dial bore gage made in Poughkeepsie and the Standard bore gages made in Switzerland. The Centralizing Plungers automatically locate the gaging contacts on the bore diameter even when the gage is inserted at an angle.
Dial indicator graduations are .0001" or 0.002 mm and each model comes with all range extensions and adapters. The indicator makes 4 revolutions for a total of .040" travel.
Tip: we recommend the single revolution dial which can eliminate accuracy and reading errors. Please request single revolution dials at time of ordering.
