Alesametri osimess 4.5-12 mm

Repeatability ± 0.2 μm. Usable with any thousandth comparator (mechanical or electronic) with Ø 8 mm attachment. Unchanged precision due to the minimum wear of the faces of the measuring needle cone. Centering safety due to the limited travel of the feelers. Easy replacement and locking of the feelers. They are used with great success for single measurement, series measurement, and for finishing-stage parts, in inspection and laboratories, for checking parallelism between two faces, for grooves, and for keyway widths. The comparator holder can be requested with a recharging button to make instrument insertion easier.
