Moore and Wright 901M Internal Micrometer

The Moore & Wright 901M Internal Micrometer is a precision measuring instrument designed for accurate internal diameter measurement in engineering and machining applications. Part of the professional 900 Series range, this metric micrometer is ideal for quality control inspections and precision engineering work where accurate bore measurement is essential. This internal micrometer features a measuring head, a set of extension rods and a spacing collar to facilitate alternative measuring ranges within its 50-210mm capacity. The detachable extension handle provides improved reach and ergonomic operation when measuring deep or hard-to-access bores. With a graduation of 0.01mm and a 10mm head range, this instrument delivers the precise readings required for professional engineering tasks. Supplied in a fitted storage case for protection and portability, the 901M conforms to BS959 Standards, ensuring compliance with recognised UK measurement standards. This makes it suitable for workshops and inspection facilities where traceable accuracy is required for quality assurance purposes.
