I have the Benetech GM130 & I'm satisfied. 🤔😊

its not .006", or 6 thousandths off. It was a difference of .0016". The 6 at the end is ten thousandths and requires an outside micrometer with a veneer scale to measure. And I am betting that the dial "very near" calipers is the less accurate of the two. Wish that you would have used a true outside micrometer for the comparison.

I have heard the same thing. I think that it is rated up to 6" and I am not sure on the bottom end of the scale.
