Bluetooth-Enabled Bore Gages (781BXT & 770BXT)

April 6, 2018

Two Bluetooth-enabled series of electronic digital bore gages with a range of accuracy and convenience features for increasing measurement throughput when inspecting internal hole dimensions. The 781BXT AccuBore Electronic Bore Gages are a trigger-operated gaging system, and the 770BXT Electronic Bore Gages, operated via thimble rotation, feature IP67 protection against dirt and coolant, making them ideal in harsh machining environments.  Bluetooth wireless technology in both bore gage series enables fast, robust measurement data acquisition capabilities without the encumbrances and limitations of cables.  Wireless technology also provides an ideal platform for manufacturers bracing to meet the comprehensive big data requirements of Industry 4.0. 

Starrett AccuBore 781BXT Gages
AccuBore gages are trigger-activated, two-point and three-point bore gaging systems with extended range. Convenient single-hand operation provides increased measurement speed, control, and throughput. A user simply squeezes the trigger, inserts the gage into the bore, and releases the trigger, producing an instant reading from a large, easy-to-read digital display. Speed and convenience are further enhanced by a repositionable indicator for left, right hand, or vertical viewing, and Go/No-Go tolerance indicator lights quickly display when a bore is within a preset measurement range.


Superior design features include mechanically-driven parallel anvils that extend simultaneously, establishing true alignment to the axis of the bore, providing consistent pressure and improved accuracy compared to spring-driven contacts which are subject to pressure variations.


Starrett 770BXT Bore Gages
In addition to Bluetooth capability, the 770BXT Electronic Internal micrometers feature IP67 level of protection against coolant, water, dirt, and dust in hostile shop conditions, making them ideal for measuring holes in work that is in process on a machine.


The 770BXT gages offer extended travel, reducing the need to exchange anvils, providing a wide measurement range. A precision ratchet stop provides correct contact pressure for accurate readings on the large easy-to-read LCD digital display.


Both the 781BXT and 770BXT Bore Gage Series feature enhanced wear life due to carbide-faced measuring contacts that are available on sizes above 0.5 in. (12.5 mm), resolution of .00005 in. (0.001 mm), and accuracy of up to .00015" (0.004 mm).  Gages also feature push-button inch/ metric conversion. Wireless output capability for SPC analysis is available via USB to a PC or RS232 connection.
