Can a diamond chain cut rebar?

Yes, No 4 or 5 (12 or 16 mm) bar is not a problem. Anything over number 8 (25 mm) is difficult. Large amounts of rebar will reduce chain life. Caution: Rebar or steel must be surrounded by concrete or aggregate material.

When does the chain need tightening?

Diamond chains tend to run better when slightly loose. It's normal for the drive-links to hang completely out of the bar.
