Product Number: 52416
Achieving accurate bore diameter and groove width measurements demands tooling that can reach confidently into confined internal features and hold a precise reading for transfer to a micrometer. The Draper Expert Telescopic Gauge Set (6 Piece) — SKU 52416 — is designed exactly for that purpose, making it a practical choice for engine rebuilds, cylinder head work, and precision component inspection in professional workshop environments. Each gauge operates via a spring-loaded plunger that expands outward to contact the bore wall. Once seated correctly, the knurled locking screw holds the plunger contacts firmly in position, allowing the gauge to be withdrawn and measured against an outside micrometer without any risk of the contacts shifting. The satin chrome finish resists corrosion and maintains a clean, professional appearance during regular workshop use. The set of six gauges covers a combined range from 8 mm to 150 mm (5⁄16" to 6"), spanning the most commonly encountered bore sizes in automotive and general engineering work. The three smaller gauges — covering 8–13 mm, 13–19 mm, and 19–31 mm — are 115 mm in length, whilst the three larger gauges — covering 31–54 mm, 54–89 mm, and 89–150 mm — are 145 mm in length. Metric and imperial ranges are marked on each gauge for immediate reference. The complete set is supplied in a PVC storage wallet with each gauge's range clearly marked, keeping the instruments organised, protected, and ready for use.
Expert Quality, for measuring of bore diameter and groove width. The spring - loaded plunger expands within the hole. Knurled locking screw allows plunger contacts to be held in position, removed and measured with a micrometer. Satin chrome finish. Supplied in PVC storage wallet with ranges marked.
