In a nutshell
The right choise for
With the Mitutoyo 169-201-10 disc micrometer, you achieve maximum precision when inspecting gears and delicate components. The 20 mm diameter disc-shaped anvils allow for stable and accurate measurement of root tangent lengths across spur and helical gears. Thanks to the non-rotating spindle, the measuring face advances linearly without twisting, completely preventing torsional damage or indentation on soft materials such as rubber, felt, leather, or foil. Covering a 0 to 25 mm measuring range, the 0.01 mm graduation and integrated ratchet stop deliver consistent, repeatable measuring force for quality control and metrology tasks. This instrument comes complete with a protective storage case and an adjusting key.
