Steel Tapered Bore Gauge

The Groz Tapered Bore Gauge is designed to accurately measuring the diameters of small holes, slots, and other similar shapes. Manufactured from high-quality stainless steel that is tapered over the entire length, this gauge features permanently engraved imperial graduations on one side and metric on the other. This makes the gauge ideal for die makers, machinists, and those who work on inspection floors.
