Dorsey Metrology International
Dial bore gages are used to quickly inspect hole diameter as well as to detect and measure all kinds of bore conditions such as taper, bell-mouth and out-of roundness. They in no way depend upon a sense of "feel" as is the case with non-indicating types. Machine operators find our bore gages to be particularly useful in making quick, accurate adjustments to bring work-pieces within tolerance. In this application, the reading on the dial tells the exact amount of tool correction needed and eliminates uncertain, "creep-up" methods of making adjustments.
The reliable accuracy for which these standard bore gages are known is due to a delicately responsive gaging plunger and a positive centralizing mechanism that correctly positions the gage in the bore. After setting to a master, diametral measurements are obtained by rocking the gage in the bore and noting the greatest deflection of the dial hand.
The regular type dial bore gage is intended for the usual situation where there is ample space in front of the bore opening. For gaging in restricted spaces, or to facilitate reading where other limitations are imposed, additional standard bore gage styles are available. If your application require additional range extension, please contact us for quotation.
Standard Style Bore Gage Features
- Available with ISO 17025 certification.
- Comfortable & ergonomic well balanced handle, can be removed to gain clearance in restricted areas.
- Optional shock proof dial indicator with .001", .0005", .0001", or .00005" (.001mm, .002mm, .01mm) resolution available in single or multi revolution models. Available with Dorsey's digital housings for use with most digital indicator models.
- Precision machined aluminum dial unit housing.
- Precisely machined cast phosphor bronze gaging head for sensitivity and durability.
- Stainless steel bore gage extension tubing in a wide variety of standard and special lengths.
- Carbon fiber or stainles steel extra length extension tubing up to 144".
- Thermally insulated high impact resistant shield protects extension tubing.
- Unique "tandem" centralizer uses matched and lapped components to ensure accurate and repeatable centralization.
- Replacable contacts available in steel, carbide or diamond.
- Proven bell crank transfer is accurate and linear over its entire range.
- Precisely machined cast phosphor bronze gaging head for sensitivity and durability.
- All bore gage sizes utilize the same dial unit housing for extreme versality.
Additional bore gage styles designed especially for applications where space restrictions or gaging positions are not suitable to use of standard style bore gages housing.

For jig boring or jig grinding machine operations; designed to avoid disturbing the machine tool setup. Also for restricted areas or applications that might be hazardous to the operators' hand.
For vertical axis bores at eye level; best choice for bench inspection applications.
For vertical axis bores below eye level.
For limited access applications.
