What is the higher accuracy of phi 25H8 reamer and phi 25H9 reamer?
This is not a problem of higher accuracy, but a problem of tolerance and fit.
H8 be a little taller. But the H8 accuracy of the reamer is not high
The 25H8 reamer is more accurate than the 25H9 reamer. The so-called, refers to the hinge hole of high precision H8 H9 high precision hole hole.
