I have noticed that there are a lot of drillers who use the 6 inch reaming shell pretty exclusively, so in this blog I wanted to talk about the other sizes available and how to know when you should use another size. Reaming shells are used to maintain the diameter of the bore hole and to make sure other drilling equipment does not get stuck down the hole. The outside surface of the reaming shell has natural and synthetic diamonds embedded in a resistant matrix.
Reaming shells come in 6, 10 and 18 inches. How do you know when do you use each size?
