You compress the ball head, insert it into the bore, release it to expand against the walls, lock it in place, and then withdraw it. The locked measurement is then read using an external micrometer for a precise internal dimension.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What range of bore sizes does this 4-piece set cover?\u003c\/h4\u003e\n\u003cp\u003eA: This set covers a measurement range of 0.125 to 0.5 inches (approximately 3.175 mm to 12.7 mm), with four individual gauges of varying sizes to handle different bore diameters within that range.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What materials are these telescoping gauges made from?\u003c\/h4\u003e\n\u003cp\u003eA: These telescoping gauges are constructed from corrosion-resistant stainless steel, making them durable and reliable for repeated use in workshop, woodworking, and machining environments.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Do I need any other tools to use these gauges?\u003c\/h4\u003e\n\u003cp\u003eA: Yes, to obtain a final measurement reading, you will need an external micrometer. The telescoping gauge captures and locks the internal dimension, which you then measure across the ball heads with your micrometer for an accurate reading.\u003c\/p\u003e\n\u003c!-- production-packaging-notice --\u003e\n\u003ch3\u003eProduction \u0026amp; Packaging Notice\u003c\/h3\u003e\n\u003cp\u003eTo maintain high stock availability and fast shipping times, our items are sourced from multiple verified manufacturing facilities.
