Product Description:

Professional Pistol-Grip Three-Point Bore Gauge – Precision Internal Measurement Solution

Experience exceptional measuring efficiency with our ergonomic pistol-grip three-point bore gauge. Designed for one-handed operation and ambidextrous use, this professional instrument delivers precise internal diameter measurements from 6mm to 300mm. The self-centering three-point design ensures accurate measurements in both blind and through holes, while carbide measuring faces (on models above 12mm) provide superior wear resistance. Complete with calibration rings for measurements up to 100mm and compatible with various dial indicators, this bore gauge is perfect for manufacturing, quality control, and precision machining applications.
