I was challenged by a recent project that involved re-roofing a jewelry store. Now, I can’t say specifically what was done for obvious reasons, but let’s just say that installing a security roof in this application involved hundreds of 5″ x ¼” lag bolts. Each of these lag bolts had to be driven through a yellow pine 2×6, ¾” torch-down roofing membrane, ¾” plywood and, finally, into the edge of a 2×4… all with no pre-drilled holes. This is a pretty grueling test for any impact driver. Providentially, I was able to get my hands on the new Makita LXDT08 Brushless Impact Driver and, honestly, I couldn’t think of a better test. I was also thankful to get the extra tool on loan, because this was going to be a lot of work.
