Review on 📏 6-inch Outside Spring Caliper by Starrett 275 by Roberto Manzer

Absolute professional precision tool. If used correctly and with the right touch, you can feel a 0.001 inch difference in size on a round shank that has been turned on a lathe. This is due to the shape of the caliper, its inherent spring tension and the tip shape that gives it this characteristic. I've used imported calipers from China and India since my business to save money. After getting this from Starrett and using it for measurements, I threw the imports straight into the trash. You will have it for the rest of your life if you don't abuse it.
