طقم مؤشر اختبار قرصي، 0.3" × 0.0005"

I was a bit worried about the dovetail mounts fitting my setup, but all three included positions work perfectly. The frictionally adjustable contacts made zeroing in on measurements quick and satisfying.

The jeweled movement is incredibly smooth, and the .0005" graduation lets me read tenths of a thou without squinting. I use it for tramming my mill head; it's been dead-on accurate right out of the box.

The frictionally adjustable contacts are a real lifesaver when I need to switch between hole depths mid-job. The jeweled movement is smooth as silk, and the .0005" graduation reads crisp and clear every time.
