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.

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.

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.
