These small hole gages are well balanced tools that are ideal for accurately measuring small holes, slots, grooves, and recesses in all kinds of work.

The radius on each gage is less than the minimum diameter to be measured, which provides the two-point contact necessary for maximum accuracy.

They have smooth, sensitive adjustment for better feel, giving more accurate measurements. The adjustment of the gage beyond their range is restricted by a safety stop that prevents breakage

Accurate measurements are obtained by slightly "rocking" these gages in the hole to be measured. This will guarantee contact at the true diameter. The final size is then obtained by measuring over the ball contacts with a micrometer.

Furnished in a vinyl pouch.

Customer Reviews (4.6 / 5 · 5 reviews)

Grace ★★★★★

The radius being less than the minimum diameter really helps me get accurate readings in tight slots without any guesswork. I’ve used them on a few small engine parts and the balance makes them feel precise in the hand.

Sofia ★★★★★

The radius being smaller than the minimum diameter made it easy to get into tight slots I've struggled with before. The balanced feel really helps you keep a steady hand when measuring.

William ★★★★★

Finally, a small hole gage that doesn't wobble in my hand—the balance is spot-on when I'm reaching into tight spots. The radius cut makes getting into shallow recesses way less fiddly than my old set.
