For the rapid testing of diameter, roundness and conicity of bores.
Especially suitable for testing batches with tight tolerances.
No rocking in the bore is required to determine the reversal point.
Therefore ideal for use in conjunction with a digital indicating instrument and for subsequent processing of measured values.
Measuring head has a hardened, hard chromiumplated guide cylinder and carbide-tipped anvils.
The carbide expanding pin transfers radial movement to indicating instrument.
