Draper Expert External Micrometer

The Draper Expert 25mm - 50mm External Micrometer is designed for measuring medium-sized components with exceptional precision. This measuring range makes it particularly useful for checking shaft diameters, machined parts, and general engineering components that fall within this popular size bracket. Constructed with an enamelled frame and heat-insulated plates, this micrometer minimises thermal expansion that could affect accuracy during extended use. The satin chrome thimble and sleeve provide smooth, tactile adjustment, whilst the 0.01mm graduations deliver the fine measurement resolution required for quality control and precision engineering work. Carbide-tipped anvils ensure long-term accuracy even with frequent use, and the integrated lock allows you to secure measurements for transfer or comparison. The ratchet stop mechanism ensures consistent measuring pressure, eliminating operator variation. Supplied complete with calibration rod and C spanner in a protective plastic storage case.
