Telescoping Bore Gauge Set, 8-150 mm

✅ Reach an awkward bore. The telescoping body enters an opening that a caliper jaw cannot reach straight on.

✅ Hold the size while measuring. Spring-loaded plungers press against the sides and the lock keeps that span until you read it.

✅ Carry it to a micrometer. Once locked, the gauge takes the bore size to a caliper or micrometer for the number.

✅ Cover a wide range. The set spans 8 to 150 mm across the options, so one kit covers many openings.
