Taper Bore Gauge 1-15 mm

A thin tapered steel strip with a metric scale, pushed into a small hole, slot or gap until it stops, so the opening can be read off the graduations at that point. It covers 1 to 15 mm, with black graduations and a satin-chrome anti-glare surface that does not rust. Handy for quick checks of drilled holes, weld gaps and clearances.
