2-6 Inch Precision Dial Bore Gauge Set – 0.0005″ Graduation – Engine Cylinder Tool

If you're rebuilding engines or doing precision machine work, you can't guess—you have to measure.

This dial bore gauge set lets you measure cylinder diameters from 2 to 6 inches with accuracy down to half a thousandth of an inch (0.0005″ grad).

It's perfect for checking cylinder wear, taper, and out-of-round conditions.

It's a new, unbranded set that does the same job as the expensive truck brands.

Comes with all the heads and extensions you need.

Just a heads-up, California residents: this contains chemicals known to cause cancer, so handle with care and wash your hands after use.
