Bore gauges are also known as cylinder tests, hole tests, bore mics, holtests, internal micrometers, hold bore gauges, or telescoping gauges. PHP 150,367.71 (exc. Only 1 left in stock - order soon. Micrometer, in full micrometer caliper, instrument for making precise linear measurements of dimensions such as diameters, thicknesses, and lengths of solid bodies; it consists of a C-shaped frame with a movable jaw operated by an integral screw. Micrometers are usually, but not always, in the form of calipers. Price Each £ 176.06 (exc. There is another kind of micrometer available called vernier micrometer, which also gives an accuracy of 0.001 mm. The micrometer is then adjusted at a dimension slightly smaller than the internal (bore) diameter of the workpiece. It has no spindle, only anvil. When a length standard bar or internal micrometer lies horizontally, supported as simply as possible at two points, it bends under its own weight into a shape that depends on the spacing of those points. 3. Depth micrometers take measurements of slots, steps, holes, and projections. Free delivery on eligible orders of £20 or more. Standard micrometers can be read by examining markings on the barrel and thimble of the micrometer, because very small distances are represented by greatly magnified rotational distances as the thimble is turned. z.
