Precision and reliability: the digital bore gauge provides internal diameter measurements with 0.01 mm resolution, enabling reliable comparative readings for quality control and machining applications. Wide, adaptable measuring range: covers 18 35 mm, 35 50 mm, and 50 160 mm with interchangeable anvils made from quality alloy steel, ensuring consistent results across different bore sizes. Durable, accurate construction: built from stainless steel with an internal scale that resists wear and maintains accuracy through repeated use in workshop and industrial environments. Complete measurement kit: includes an inner diameter cylinder gauge, measuring rod, connector set, and protective outer box, providing everything needed for immediate use in machining, engineering, and quality inspection tasks. Practical use scenarios: Inspect engine cylinder bores and hydraulic components in automotive manufacturing or to verify bore size and tolerance. Set up and verify bore dimensions during CNC boring operations and machining processes. Check bores in gear housings, valve bodies, and piston assemblies to ensure proper fit and quality control.
