Sealey 6 Piece Telescopic Bore Gauge Set

The Sealey 6 Piece Telescopic Bore Gauge Set is a precision measuring tool designed for accurately determining internal bore diameters in engineering and machining applications. This comprehensive set covers a measurement range of 8-150mm (5/16"-6"), making it suitable for a wide variety of workshop tasks from small precision bores to larger cylinder measurements. Each telescopic gauge features a spring-loaded plunger that expands within the bore to match its internal diameter. Once the correct size is achieved, the plunger can be locked in position, allowing the gauge to be removed and measured using a micrometer for precise dimensional verification. This two-step measuring process provides accurate readings for quality control, engine rebuilding, and general machining work. The gauges are finished with chrome plating for corrosion resistance and long-term durability in workshop environments. The complete 6-piece set is supplied in a convenient storage wallet with clearly marked ranges, helping you quickly select the appropriate gauge for each measuring task and keeping the tools organised between uses. Features and Benefits: • Spring-loaded plunger mechanism for easy bore measurement • Chrome plated finish provides corrosion protection • Supplied in storage wallet with marked ranges for quick gauge selection • Wide measurement range from 8-150mm covers most common applications Specifications: Brand: Sealey Nett Weight: 0.27kg Range: 8-150mm(5/16"-6")
