110 AC here...... would love to have a cordless but I bring almost all my projects to the garage/driveway area anyway..... I think a generator would suit me better than cordless stuff.... I'm a big power hog and cordless stuff is great and handy (couldn't live without cordless drill as it gets used so much as a bit driver) but need nonstop power and lots of it for cutting and what-not.... of all the cordless high power draw tools I've used, they have to be big name brand to really do the job and make me impressed and thats a lot of money to invest in tools, plus the cost of the batteries when they need replaced is sky high. I think a generator would be more affordable than buying all the tools i'd need in a GOOD cordless version, that I already own those tools that simply need a power source....

But again, all my projects come within range of an extension cord so I keep it simple for now. I always use some used motor oil as cutting oil when I'm drilling holes in steel, never really done that with sawzall but should work fine...... Normally the cut isn't big enough to worry about it, and I have a harder time not bending the blade than keeping teeth on it....
