Engineering & Design Features
This Original Engineering measurement set utilizes carbide-tipped contact points to maximize wear resistance and maintain long-term dimensional stability. The specialized hollow grip design effectively isolates the gauge from operator body heat, preventing thermal expansion errors during prolonged inspection cycles. The interchangeable anvils allow for rapid reconfiguration, minimizing downtime during multi-diameter inspection tasks.
Industrial Application
The 511-921-20 is critical for precision machining environments, specifically in automotive engine manufacturing for cylinder block bore inspection, and in aerospace engineering for verifying bearing housing tolerances. Its ability to detect out-of-roundness and taper in deep bores makes it indispensable for strict quality assurance protocols.
Logistics & Availability
Standard Lead Time applies based on global distribution networks. Verify Technical Compatibility with existing calibration masters and setting rings prior to integration.
