Sawsall WILL cut Boron(with the right blade). We're fast approaching the limits of what ANY cutter will do if we keep employing the "wrap"(layered) technology with Boron reinforcements that are showing up now. A GOOD sawsall will be a REQUIRED weapon of choice in the future.
...and it will take the "right"sawzall blade a lot of time, multiple blade changes, and a lot of heat generation to get one post cut.
We carry multiple sawzalls. Their use is becoming more and more limited as the boron-rated cutters and combi tools show what they can do and how fast they can do it.
