Here is a question to all who have done a mix-n-match leaf spring. What did you use to drill out the holes in the XJ main leaf. I need to drill out a couple of the old leafs from 5/16" to 3/8" and I have used steel, titanium nitrate coated, and cobalt bits and they are kicking my ass?:bawl: What am I doing wrong I'm using a very strong 1/2" drill with cutting oil and I have also tried a drill press with cutting oil and I have gotten very little progress and a lot of dulled bits.:anon: Any help will be appreciated.
