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. Constant measuring force as a result of built-in spring, thus eliminating user influence. Measuring head, holder, depth extension, right angle attachments and depth stops are part of an extensive modular system.
