Best Dial Bore Gauge FAQ: Your Questions Answered
Q1: What is a dial bore gauge used for?
A1: A dial bore gauge is used to precisely measure the internal diameter of holes, cylinders, and bores. It’s essential for detecting variations like ovality, taper, or wear, which is crucial in engine rebuilding, machining, and quality control.
Q2: What’s the difference between a digital bore gauge and a dial bore gauge?
A2: A dial bore gauge uses a mechanical dial indicator with a needle to display measurements, requiring careful interpretation of markings. A digital bore gauge uses an electronic display, showing the measurement numerically, which is often easier and faster to read, reducing potential human error. Both can offer high precision, but digital typically offers clearer readouts.
Q3: How do I calibrate a dial bore gauge?
A3: To calibrate a dial bore gauge, you’ll typically set it against a master ring gauge or a micrometer set to a known dimension. You then adjust the dial indicator to ‘zero’ at that known dimension. This process ensures the gauge is accurately set for your specific measurement range before you begin taking readings of the bore.
Q4: What accuracy should I look for in a dial bore gauge?
A4: The required accuracy depends on your application. For general engine work, a gauge with 0.0005 inch (0.01 mm) or 0.001 inch graduations is usually sufficient. For high-precision machining or metrology, you might need a gauge with 0.0001 inch (0.0025 mm) resolution for extremely tight tolerances.
Q5: Can I measure deep cylinders with all bore gauges?
A5: Not all bore gauges are designed for deep cylinders. You should check the “measuring depth” specification of the gauge. Some models, like the Fowler reviewed above, offer extended depths (e.g., 9.5 inches) specifically for such applications. Standard gauges typically have shallower depth capabilities.
Q6: Are carbide-tipped contact points important for a bore gauge?
A6: Yes, carbide-tipped contact points are very important, especially for frequently used gauges. Carbide is extremely hard and wear-resistant, meaning these contact points will maintain their accuracy for a much longer time compared to standard steel points, especially when measuring abrasive materials or for prolonged periods.
Q7: What additional features should I consider when buying a bore gauge?
A7: Beyond accuracy and type (digital vs. dial), consider features like self-centering mechanisms for ease of use, insulated grips for comfort, the range of measuring anvils/probes included in a set for versatility, and the durability of construction (e.g., stainless steel, all-metal clamping). A protective storage case is also highly beneficial for tool longevity and organization.
