Hi

Just a quick question from any tradesmen or diy enthusiasts? I am looking to buy a cordless screwdriver/drill for a christmas present. I see voltages of 3.6v, 12v 18v etc. What would be a good voltage for general and slightly heavy work, i.e drilling small holes, screwing wood, sockets, plasterboard etc

Thanks
 
I've a worx 24v. Cheap, powerful enough and will drill small masonary holes with the hammer action.. If you're drilling holes i definately wouldn't go for anything less than the 18v...
 
The higher the voltage. the more powerful the drill will be.

This is because of Ohms law ! (the only electricity law I remember from school).

Amps = Volts / Resistance

For a given resistance, if you increase the volts, the Amps will also increase. Volts * Amps = Watts, and the more Watts, the more powerful the drill.

My battery drill is 14.4Volts, it's fine for drilling holes in wood, and also masonry. But I was drilling a hole in a piece of metal today, and it took my drill ages (about 3 minutes to make a 3mm hole in a thin sheet of metal) :(
 
I use a 12v bosch model all of the time. I find that it's lightness makes it very easy to use (especially overhead) and for getting in to small areas.
I wouldn't use it for drilling steel though and it doesn't have hammer action.
My main advice thought is to go for a known make and one that comes with two batteries.
 
18V plus is defo the way to go..........my dad just bought an 18V makita from B&Q with a drill bit package fro €150....I was a bit suspicous before I saw it, giving it was that cheap.....but it is the job in fairness for that price
