Bore Gauge Set 50-160mm Dial Cylinder Measuring Tool 12 Rods

A bore gauge set for comparative measurement of internal diameters in cylinders, machined bores and similar openings. It covers a 50-160mm range and is suited to workshop inspection, machining checks and fabrication work where consistent internal measurement matters.

Used for checking bore size, wear, taper and out-of-round in cylinder bores and other internal surfaces, this type of dial measuring tool is common in engineering shops, manufacturing environments and repair workshops. It is useful when comparing bore dimensions during machining, servicing or component inspection, helping users monitor changes accurately rather than relying on estimation. For regular workshop use, the wide measuring range makes it practical for handling different jobs without needing separate gauges for each size.

Self-centring measuring heads help the gauge sit correctly in the bore during use, while the guide bridge supports stable comparative readings. The set includes a dial bore gauge, 12 measuring rods covering 55-105mm, four spacer rings in 0.5mm, 1.0mm, 2.0mm and 3.0mm sizes, plus a 60mm extension bar for added reach where required. A stated tolerance of 0.01mm makes it suitable for close measurement work, and the included components give you flexibility when setting the gauge for different internal diameters. That makes it a sensible choice for repeated measuring work where access, range and consistency all matter.
