220 volt to 120 on screw gun

4010 lyle · Sep 22, 2013

I have a dry wall drill that was made for countries that run everything on 220 volt. Would it work to put 120 cord end and use it? If it worked would it run half speed? Thanks for letting me pick your expertise.

I think all drills/screw guns are universal motors, so it should run on very slow on 110v. Half the volts, half the current and 1/4 the power.

I've never done it. Not totally sure is the variable speed control will have a problem. Better not listen to me, because I'm not a EE, just a BUBBA.

Never try to run a 110v motor on 220v. It will let the smoke out of the motor real fast. I saw BUBBA make that mistake.

I don't think that will work out that way. If it has an electronic speed control, it wouldn't work on half the voltage.

Unlike some other electric motors, I have never seen a portable power tool that you could switch voltage on. It would take a new field winding and armature to convert it, along with the speed control switch.
(Not cost efficient to buy the parts.)

You might rig a cord to a stove or dryer outlet to run it as is.

Brush-type motors like those in drills and screw guns are essentially DC motors. So, yes, in theory it will run at half its rated speed on 120 volts. Given that drywall guns usually run at 4000 rpm, that might not be a problem. The real question is whether or not it will have enough torque to do the job. My guess is it will work at least as well as a cordless gun. Might as well give it a shot.

You have 2 things to worry about with a foreign 220 v tool

Frequency and voltage

Voltage is easy hook it to a dryer outlet and you ll get 220 v

Now frequency. The us is 60 hz and most European countries are 50 hz . So your screw fun is going to run a little faster - over speed

BUT it won't last as the hz difference will cause the motor to heat up and eventually smoke

Sell it on eBay to someone overseas and buy one ment to be run in the us

Could always run it from a generator. Adjust the engine rpm to give you 50 cycles and then adjust the voltage regulator to give you 220v. Some generators can be adjusted and some can't. Some will run at the lover hz and adjust the voltage automatically and some won't

In the end not worth the effort. Cheaper to buy a tool made for the us voltage and hz standard

You can buy cheap converters that have the correct plug on them.
