They generally have more power and don't go dead when you need them.
Battery operated tools are also electric, but I think you mean corded and cordless. Corded can be more powerful and will run "forever", but you have to drag the cord around. Cordless are easier to move around with, but have to be recharged regularly.
I love using battery operated drills but I never run out of power when I use corded drills-- I don't have to charge one and use one and I don't have to spend $70 for each battery, and I don't have to worry about spending $45 more for battery chargers when workers crush my charger. However: I must say Cordless Drills also Rock if you hate to be swinging cords over your shoulder all the time.
Corded power tools are generally more powerful and you don't have to re-charge all the time.
There are only a few parts and components that separate a cordless electric drill from a corded electric drill. Having a battery instead of a cord is the biggest difference.ÊÊ
Cordless nail guns are good, but not for a professional framer. Corded nail guns have much more penetration.
That's a tough task for a battery operated tool. You really need a hammer drill. There's a nice Milwaukee cordless hammer drill at Sears but it costs $350. My corded hammer drill cost only $79. To me that is a huge difference for the convenience of cordless.
Cordless drills have only the power available in their built in batteries or battery packs, which must be recharged when depleted. Corded drills plug into an electric outlet and do not run from battery power. CORDED DRILL -- WITH SUPPLIED WIRE WHILE USING AND UNCOMFORTABLE AND CAN DO LIGHT, MEDIUM AND HEAVY DUTY JOBS. CORDLESS DRILL -- WITH SUPPLIED WIRE WHILE CHARGING AND COMFORTABLE TO DO LIGHT AND MEDIUM JOBS. WITH VARIABLE SPEED AND CLUTCH.
Corded tools are almost always more powerful. You don't have to take care of batteries. They are usually lighter for power available.
Not enough info, but divide the Amp/hr rating of the battery by the amperage draw of the machine to get ad approxiamation
In general they do,but the latest 18 and 24 volt batteries are very close.Of course the electricity will keep coming through the cord a lot longer than it comes through
A cordless electric knife would be much safer than a corded one, as you are not going to trip over any cords, and possible fall (especially onto anything hot). Also, there are no cords that could get wet and cause electricity dangers.
The black and decker corded trimmer does feature an emergencey shut off feature.
