Mitutoyo 141-101 Inside Micrometer Set 25-50mm

The Mitutoyo Series 141 is an analog inside micrometer that measures the diameter of a bore over a wide range by combining interchangeable rods and spacing collars. It suits toolrooms, machinists, fitters and inspectors who measure bores of many sizes with one tool. Each rod is marked with its measuring range. It reads to 0.01mm.

There are three sets: 25 to 50mm (2 rods), 50 to 200mm (3 rods) and 50 to 300mm (5 rods). Graduation is the smallest step you can read on the scale. Accuracy is a separate figure. It is the maximum permissible error, which is the most the reading is allowed to be out. The spindle feed error, the difference between the highest and lowest reading error across the head, is 3µm. An extension handle for deep bores is included with sets up to 300mm.
