Stainless Steel Dial Bore Gauge | 0.001mm Accuracy | 50–160mm Range
Take the guesswork out of precision measurement with this professional-grade Dial Bore Gauge. Designed for machinists, automotive technicians, and woodworking enthusiasts alike, this gauge delivers repeatable, high-accuracy inner diameter readings across a wide 50–160mm (2"–6.3") range — all without the need for batteries or complex setup.
Key Features
- Wide Measurement Range: Covers 50–160mm (approx. 2"–6.3"), making it suitable for engine bores, cylinder inspection, and a broad range of industrial and workshop machining tasks.
- Three-Point Synchronous Feedback: The three-point contact structure simultaneously collects dimensional data, allowing you to assess roundness, cylindricity, and taper of any workpiece with a single pass.
- 0.001mm Resolution: The matched dial indicator provides ultra-fine 0.001mm resolution with a graduation of 0.01mm and a measuring deviation of just ±0.015mm — ensuring consistently accurate results.
- Battery-Free Mechanical Operation: The all-mechanical design features a clearly marked dial face and adjustable probes. No power source needed — just zero, measure, and read.
- Rugged Stainless Steel Construction: Built with stainless steel components for long-term durability in demanding workshop and production environments.
- Includes Hard Storage Case: Comes packed in a hard plastic storage case to protect your gauge between uses and during transport.
