BAKER bore gauges allow rapid and accurate checking of bores for size, Ovality and taper as also wear of bores like Engine Cylinder bores etc. in the workshop or inspection room. All bore gauges operate on the proven principle of two diametrically opposite measuring points, one fixed and one moving with a spring loaded centralising shoe. To check the actual size of bore, the gauge must be set to size with a bore master (Master Setting Ring) of known diameter which is close to the size to be measured. Inserted into the bore, it is necessary to "rock" the gauge slowly to locate its measuring axis to the bore shown by the point of reversal of the indicator hand. The reading at that point is the deviation from set normal size. A range of interchangeable extension rods allows a single instrument to cover wide range of bore sizes.
A gauge developed specifically to monitor compliance with the legal requirement for minimum tread depth. Additionally, it is useful for gauging general tyre wear in the range 0-8 mm.
Three most commonly required measuring tools in an exquisite wooden box. Many workshops and jobshops have found this PMI set as an invaluable aid to their work. Many corporate houses have chosen PMI set as their industrial gift article because of its aesthetics and high utility value. A must for Engineering Colleges and Technical Institutes.
