Draper 6 Piece Telescopic Gauge Set PTGS

The Draper 6 Piece Telescopic Gauge Set is a precision measuring tool designed for accurately determining bore diameters and groove widths in engineering and machining applications. This comprehensive set provides coverage from 8mm up to 150mm, making it suitable for a wide range of internal measurement tasks where direct measurement with standard tools isn't possible. Each gauge features a spring-loaded plunger that expands within the bore or groove being measured. The knurled locking screw securely holds the plunger contacts in their expanded position, allowing the gauge to be removed and the precise dimension measured using a micrometer. This two-step process ensures accurate internal measurements in cylinders, bushings, and machined components. The gauges are finished in durable satin chrome for corrosion resistance and longevity in workshop environments. The set is supplied in a practical PVC storage wallet with measurement ranges clearly marked on each gauge, ensuring quick selection of the correct tool and organised storage between uses. Ideal for automotive technicians, machinists, and precision engineers requiring reliable internal dimension measurement.
