The Draper Expert External Micrometer is a precision measuring instrument designed for accurate dimensional measurement in engineering and workshop applications. This metric micrometer offers measurements from 0 to 25mm with fine graduations of 0.01mm, making it ideal for quality control, machining verification, and component inspection tasks where accuracy is critical. Built to professional standards, this micrometer features an enamelled frame with integrated heat plates to minimise temperature-related measurement errors caused by hand contact. The satin chrome thimble and sleeve provide smooth operation and clear reading of measurements, whilst carbide-tipped anvils deliver excellent wear resistance for long-term accuracy. A ratchet stop mechanism ensures consistent measuring pressure, preventing over-tightening that could damage components or distort readings, and a lock function allows measurements to be secured for recording.
