Bore Gages

At Transcat, you can select from the industry’s most durable electronic, mechanical and digital bore gages in two- or three-point contact formats. We offer gages to measure hole diameters and display the results in easy-to-read formats. Mechanical bore gages show vernier or dial results, while electronic tools use a digital display. Our bore gage sets and individual instruments come from the premier manufacturers of precision measurement gages, such as Mitutoyo and Starrett.
