Key Features & Benefits
-
±0.001mm Micron Accuracy: Ensure your components meet the tightest tolerances with a gauge built for exacting standards. The included high-precision dial indicator delivers clear, reliable readings.
-
Unique Crank-Action Design: The patented “U-shaped” crank mechanism allows for effortless, one-handed operation. It ensures the gauge is always perfectly centered in the bore for consistent, repeatable measurements every time.
-
Wide Measuring Range (50mm to 450mm): This versatile set comes with multiple interchangeable anvils and extension rods, covering a broad range of internal diameters from 50mm up to 450mm (approx. 2″ to 18″).
-
Robust & Stable Construction: Machined from high-quality, thermally stable materials to resist wear and environmental changes, guaranteeing long-term accuracy and a lasting investment.
-
Fast & Intuitive Operation: Dramatically reduce inspection time compared to telescopic gauges or hole mics. The direct-reading dial indicator provides instant results, boosting your workshop productivity.
-
Complete Ready-to-Use Set: Arrives in a durable wooden or metal case with all necessary anvils, extension rods, a precision dial indicator, and setting rings (or a micrometer) for fast, accurate calibration.
