Bore Gauges

Bore Gauges
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.

    Salient Features:

  • Small bores from 10mm to 18mm
  • Highly versatile 18-50mm bore gauge covers a large range for which one needs to generally purchase 2 bore gauges having ranges 18-35mm and 35-60mm.
  • The third bore gauge covering a range of 50-150 mm, is widely used in Automobile, Aircraft, Engine and Pump manufacturers.
  • High wear resistance due to carbide-tipped stationary and moving anvils.
  • Extra wide bridge ensures automatic centering in the bore. Self-centralising feature of this bore gauge ensures that the measurement can be done with minimum of skill.
  • Furnished in a sleek wooden case containing measurement anvils and extension rods with necessary tools.
