Achieve precise internal diameter measurements with this metric telescoping bore gauge set. The knurled satin-finish body provides a secure, non-slip grip for positive adjustment, while the hardened, radius-ground plungers ensure consistent, accurate readings when used with a micrometre. Ideal for engineering, machining and workshop applications, this tool covers a measurement range of 8 to 12 mm, making it suitable for a wide variety of small bore inspection tasks. For even smaller diameter measurements, simply pair it with a compatible small hole gauge to extend your measuring capability. The satin finish helps reduce glare under strong lighting, improving readability and control. Supplied in a durable plastic wallet for easy storage, organisation and protection, this gauge is an excellent addition to any professional or hobbyist toolkit requiring reliable internal measuring performance.
