Precision Components Grade 25 Inspection Gage Ball Set for High-Accuracy Dimensional Calibration

The Precision Components Grade 25 Inspection Gage Ball Set comprises 53 high-precision chrome steel alloy spheres hardened to Rockwell C 63 and ground to a 1.5 micro-inch surface finish. These calibration-grade gage balls maintain dimensional accuracy within ±0.0001" size tolerance and sphericity within 0.000025", ensuring exceptional reliability for metrology applications.

Key technical applications include:

• Internal taper and cone measurement for precise determination of taper angles, opening diameters, and gauge line depths essential in tooling and precision engineering.
• Hole, slot, and depth inspection enabling measurement of small bore diameters and slot widths inaccessible to conventional tools, supporting critical quality control in manufacturing and bioprocessing instrumentation.
• Verification of complex geometries, including gear pitch diameters, countersinks, and screw threads, critical for high-precision mechanical components used in biotechnology and biomedical engineering.
• Calibration and setup of other precision instruments such as micrometers, supporting maintenance of traceability standards in molecular diagnostics and synthetic biology workflows.
• CMM reference points, playing an integral role in coordinate measuring machines for accurate part alignment, crucial in biomanufacturing and microfabrication environments.

Included with the set is a certificate of conformity and a protective carrying case, facilitating compliance verification and convenient transport. This inspection gage ball set is widely adopted in research fields requiring high-accuracy dimensional standards, including biotechnology, biopharmaceutical production pipelines, and advanced synthetic biology instrumentation.
