Re: Which has the better cordless 18v. drill: Bosch or Hitachi

| Just checked out the Panasonic web site. First thing that struck me were
the prices! $510 for the top cordless drill model (15.6V Multi Drill &
Driver with 1/2" Keyless Chuck). As you say, all nice and compact. But the
high price made me think that Panasonic tools must be an elite brand. Then
checked out prices for these very same Panasonic models at several online
retail tool vendor sites, where I found the prices to be much more in line
with the competition. For example only $299 (virtually half the price) for
the above model at Tool Authority
(http://www.toolauthority.com/manufacturers.php?MID=21). One observation
though, in general the Panasonic cordless driver lineup seems to offer
somewhat less torque than competition such as Hitachi or Bosch drivers, even
in models where the voltages are the same. But I guess the extra compact
design of the Panasonic drivers I guess could very well account for this.
BTW, another question I have just came to mind: what is the
significance of "Ah" (e.g. 2.0 Ah, 2.5 Ah, 3.0 Ah, 3.5 Ah, and so on)
rating of a cordless tool's battery-capacity? Up til now I had just assumed
this referred to amperage-per-hour output (which, like the amperage rating
of a corded tool, if multiplied by the voltage [e.g 12. for 12v. cordless
models, between 110 and 120 for all corded models] yields maximum energy
output [or consumption, respectively] per hour). But I'd like to somehow
find out for certain from someone if I am on the right track in this or
not... Because if this is true how can the most powerful cordless tool
possibly keep pace with an average corded one which has far higher, both,
amp and voltage numbers? Thanks.

The AH rating is how much power is available. Some tools use that power
more efficiently than others.
None can truly keep up with a corded tool long term. They may have equal
power for a short time, but there are compromises to get decent run time
from the batteries.

Going to be interesting to see how the new Milwaukee V28 Ion line holds up.

I love the Pit Stop and Helicopter commercials. Check their web page if you
haven't seen them.

Hadn't seen the helipcopter commercial before. Thanks for the link. :-)

Consumer reports says that the drill they tested had quite a bit of
power. So much so that it burned out its motor during their test.
Ouch.

Further to my inquiry below, does anyone happen to know how a typical corded
driver would rate if actual torque specifications were provided for corded
drivers like they are for cordless? For example, roughly how many
inch-pounds of maximum torque from, say, my 4.6 amp (Skil "Slugger", geared
to rev up to 2600 rpm) corded drill?

| I am not that farmiliar with the Panasonic line as they are not retailed
widely in my area but I can tell you that the Ah does stand for amp hour and
tells how many amps are delivered for one hour by the battery or vise versa
1 amp for x number of hours. So the higher the number the better, but no
cordless tool will be able to compete with a good corded rival. As for
prices on the Panasonic site I would think like most manufacturers they will
publish the full list price on their site so their resellers can always
sell for less than that price. Many manufactures don't list any prices and
thoese that do usually put up a high recomended list price which no one
sells it for and that price makes every reseller's price look good.
I personally like Porter Cable the best .
hope this helps

Amazon seeks to have the best prices on Panasonic drills. That's where I
got mine several years ago and still love it.
