RUNNING A CORDLESS DRILL ON HOUSE CURRENT

[venomballistics]

See post #9, it works. http://smith-wessonforum.com/lounge/192408-cordless-drill-question-poll-decision-has-been-made.html

yeah .. this does work ... for a short time, and each time gets shorter.

I soldered the cordless battery to a cord and some alligator clips that then connected to a motorcycle battery. This in theory gave me an almost unlimited supply.
The hitch came when after my son used the setup on a project, he had left my tools sitting on the driveway, and after I hollered at him he picked up the tools and threw them in a pile in the garage. The battery was not properly protected from a short and in no time, my garage was on fire.
I think that it would have been better to have rebuilt the factory battery.

and thats why you never leave any electronic project in open air.
Proper enclosures and plugs keep these issues at bay.

Please read no critique or ill will in this response as I know times have changed.

HOWEVER, I wouldn't have had the balls to not properly return my Dad's tools to where they belong and I'm pretty sure I wouldn't have aged a day more had I left them out in the driveway and then tossed them in a pile after being TOLD to pick them up. I'm pretty sure I wouldn't have made it past the driveway part!

Almost all my tools are corded and expect them to last forever but I find it real handy for quick jobs to keep one cordless drill/driver. I suffered through the Dewalt Nicad with batteries not holding a charge and eventually having a battery life of driving one screw. I switched to a Makita lithium and the batteries hold a charge for months and last a long time. It's worth the extra bucks for the convenience. Any real work I haul out the corded tools.

Switching power supplies

Ham Radio suppliers like AES have switching power supplies that deliver 5-15VDC @ 30Amps for probably less than you would pay for a couple sets of batteries.

switch mode into a motor is a big smoldering no no.
inductance aint always your friend

My old Makita 9.6 volt drill is still going, but it's still using the older black nicad "banana" batteries while the silver lithium-ion ones have quit. Otherwise, everything else is on a cord. The corded tools generally outwork the portables, size for size, and as others have said, last a lifetime. I have a half-dozen Milwaukee drills and saws, a couple of them 30+ years old, and some Porter-Cable, Makita and Bosch tools. I've been pleasantly surprised at the quality and endurance of Ridgid tools.
And to the OP - don't overlook a Bosch hammer drill if one comes along. We've used them commercially for years and they are equivalent to our Hilti tools. The Hilti line was popular when the rep in the red truck would show up at a job site with a replacement tool in the nick of time. They're good, but Bosch is, too.
