Precision where blind‑hole bores matter
The self‑centring three‑point contact mechanism ensures coaxial alignment inside blind holes, reducing measurement variability compared with two‑point probes. With a measuring range of 6.0–8.0 mm and an analogue vernier controlled fine adjustment, this instrument is optimised for small‑diameter bores where repeatability is critical. The device’s geometry minimises radial play so that each measurement reflects the actual bore diameter rather than positioning error, which is particularly valuable in small‑component assembly and quality control workflows.
Exceptional reading and repeatability for workshop standards
Equipped with a mechanical reading division of 0.001 mm, the instrument offers a fine visual resolution while the stated accuracy of ±0.004 mm provides a clear performance expectation for routine inspections. The analogue vernier design gives tactile feedback during measurement, enabling experienced operators to control contact force intuitively. This combination of high resolution and guaranteed accuracy supports process control in machining and metrology tasks where small deviations can affect assembly fit or functional tolerances.
Durable contact faces for industrial use
The micrometre is fitted with hardened measuring faces (HM) to withstand repeated contact with workpiece surfaces and abrasive contaminants found in production environments. These robust faces preserve the geometry of the contact points over long service intervals, which reduces drift and the need for frequent re‑profiling. In practice, hardened faces extend usable life and maintain measurement integrity when inspecting ferrous and non‑ferrous components during serial production.
Designed for blind‑hole measurement and simple handling
Specifically configured for blind‑hole bores, the three‑point contact and compact body (length 54.5 mm) permit access to confined features that larger gauges cannot reach. The instrument includes an adjustment ring (setting ring 6) that allows controlled extension of the contact arms, making it suitable for varied hole depths within the stated range. Its compact, mechanically driven construction requires no batteries and integrates easily into inspection benches, making it a practical choice for laboratories and on‑shop measuring stations where robustness and low maintenance are priorities.
