Boretti boring gauges OSI2W 1-4 mm

Repeatability ± 0.2 μm. Usable with any thousandth comparator, mechanical or electronic, with Ø 8 mm connection. Unchanged precision due to minimal wear of the measuring needle cone faces. Centring safety due to the limited travel of the feelers. Easy replacement and locking of the feelers. They are used with great success for single measurements, series measurements, and for parts during finishing, 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.
