Frequently Asked Questions
What size holes can a small-hole bore gauge measure?
Small hole bore gauges are designed for narrower internal diameters than standard bore gauges can reach; the exact range depends on the specific contact points fitted. Needs verification — confirm this model’s measuring range from the datasheet.
How is a small hole bore gauge different from a standard bore gauge?
A small hole bore gauge uses finer, spring-loaded contact points sized for narrow bores, while standard bore gauges use larger anvils suited to bigger diameters. Both work on the same contact-measurement principle.
How do you set up a bore gauge before measuring?
The gauge is typically zeroed against a known reference, such as a micrometer or setting ring, matching the expected bore diameter. This ensures the reading reflects the true internal diameter of the part.
What is a bore gauge used to inspect?
Bore gauges are used to check the internal diameter of machined holes, bushings, valve seats, and cylindrical bores where tight dimensional tolerances matter.
Can a small hole bore gauge be used for through-holes and blind holes?
Suitability for blind holes depends on the contact point design and probe depth of the specific model. BTSA also carries a dedicated Bore Gauge for Blind Holes — ask BTSA which model fits your application.
How often should a bore gauge be calibrated?
Calibration frequency depends on usage and your quality system’s requirements; many workshops re-verify bore gauges against a setting ring at each use and formally calibrate on a set schedule. BTSA operates NABL-accredited calibration services in Chennai and Hyderabad.
