For heavy duty work - like driving screws - I like a corded 3/8 or 1/2`
drill and an extenstion cord of at least "12 gage", (I have a fifty foot
'10') pluged into a 20 amp circuit.
Guy accross the street tried doing some heavy work and couldn't
understand why the plug on his '18 gage' melted after 15 min.
Why the 120 volt corded drill? Much more power than any battery operated
drill and much cheaper.
Longer run times between recharges of the battery packs. Marginaly more
If you are going to build a deck, get a "CORDED" drill and add a dry wall
adapter to limit screw travel. Or for about $100. you can get a corded dry
wall screw gun and have that feature built in. IMHO the corded models get
heavy after several hundred screws and the bigger the battery pack, the
heavier it is. Corded drills are relative light weight and very strong
compared to a 18 or 19.2 volt mode.
No, it is not "marginally more power", it is DRASTICALLY more power. I
have owned 9.6v DeWalt, 16.8v Craftsman, 19.something Craftsman, and our
tool crib has 24v Dewalt. The power goes up markedly with each voltage
increase. And I am talking about driving #14 screws into mahaogany,
maybe a few dozen at a time. Into poplar, pine or soft lam beam I can
slam them in with no pilot holes at all if the motor is strong, which
saves a bunch of time. Buy the big one. Any brand, most are Chinese
Of my three cordless drills, a Dewalt, a Porter Cable and Metabo, the only
one that stands up to repetetive work is the Metabo 15.4. It is not the
size of the battery, it is how the drill is geared. A 450 hp Kenworth can
tow in excess of 100,000 pounds, could you do that with a 750 hp race car?
But if the truth be known, I agree with Leon, for a deck I would use a
corded 120v drill. Why would you lay a beating on a cordless drill when you
are that close to a power source.
FWIW ... anyone interested in getting a below par cordless tool battery
"rebuilt" and operating better than when it was new, definitely give
Primecell a try:
I just sent them my second DeWally 18v. The first one I sent them came back
with noticeably more power, and a _much_ longer life before re-charging.
It will end up costing the retail price of one battery to upgrade two ...
well worth the $$, IMO.
How do you drill with that impact Makita of yours..
I have had a similar problem with Bosch drills... Starting in 1986 I broke 3
all in the first day I used them... Oddly a Bosch rep got me to try one and
it broke when I used it at a WW show... All of them had a problem in the
gears. I started with a Panasonic and those are superb. Still using 2, 9.6
DeWalts and a Makita right angle cordless. The battery is about pooped on
the Makita, it does not hold a charge very long, but it is about 20 years
old.. ;~) I got the extra DeWalt because it was cheaper to buy in a kit
than to buy 2 new batteries. Still using the original DeWalt cordless that
is 7 years old.
It's primary function in my shop is screwing; not drilling. However,
with the hex bits, you CAN drill with it too. I'm not going to invest
in MORE bits, just so I can say I use it for drilling too!
I would agree with this poster. A corded drill will have much more
power for longer than a cordless drill, assuming a reasonable
extension cord. The cordless drills (I have four) are best when a cord
would get in the way, or is not available. MOstly, when looking at the
larger battery voltages, weight is a major factor. I use 9.6v or 12v
cordless for overhead or other 'raised' elevations, because of the
weight. For a deck, where you will mostly be working downwards, the
corded drill is a fraction of the cost and a better solution.
Also, in general, the larger battery size will give you more screw
driving time before the battery needs a recharge. If you are going to
drive a dozen or so screws, the smaller battery sizes will work fine.
And the opposite for driving a lot of screws. The number of screws
that could be driven on a single battery charge used to be a major
criteria in the Fine Woodworking tests.
Also, for a deck. consider the new auto-feeding screw systems. You can
buy a complete system (drill and feeder), or just the feeder. When I
expand my deck next spring, I'll probably get a feeder to put on my
corded DeWalt. There is even a lo-o-ong model for standup work. I
haven't tried one yet, myself.
For a deck I would think that the charging time would be as important as
the battery voltage and capacity. You're going to be going through
batteries every 30-60 mins, so you'd need a model with a quick charger. Or
save a lot of $$ and just get a corded drill. You're already going to be
out there for a while so a lot of the benefits of the cordless (quick
setup) aren't really valid. Plus you'd probably save more time with the
corded drill due the its more powerful motor.
