Does anyone have this 5" Double Cut Saw SKU 68316? If so, what do you
think of it, especially for steel and aluminum? I have other devices
to cut each but it would be nice to have something like this if worth
a flip.

I know that are metal cutting circular saw blades but they are
expensive.

Thanks for any comments.

Is the Patent on the dual saw up? or did HF just rip them off?

Harbor Freight doesn't manufacture anything.

The patent could have expired, or the owner of the patent could have
licensed it to make more money.

Not sure but the "original" was an Australian design. We have two, one
the newer Craftsman unit with the larger motor and blades and the other
is a Duo-Saw. Both work well and the BIG benefit for the Fire Dept is
that they will cut through just about anything on a car without changing
blades. They also generated less heat and sparks so using them on
vehicles is safer than using a normal chop saw. You can take out a side
window then cut though the pillars and glass like butter. Less mess and
safer because the blades are smaller and more controlled than most other
tools.They are also a LOT lighter than most other cutting tools as well.
Quieter as well.

You sound like the infomercial.
None of what you cite is necessarily due to the counterrotation claims. Why
would counterrotation reduce sparks?
It's the net pitch of the blade.

Did sears rip it off ?

Actually there is a lot to see ito infomercial sleight-of-hand -- but no one
really seems innerested in the details.
I think analyzing those bull**** infomercials are great educations, esp. for
newbies or the unwitting.

See my 5/15 thread, Dual Saw Infomercial.
What's HF charging?

Dudn't really matter, cuz the concept is basically bogus, as someone else
indicated.
Yer better off with a fine-toothed trim saw, or any kind of blade on a 4
1/2" angle grinder.
Or a fine-toothed blade on a 7 1/4" circ saw, which you proly already have.
Heh, or a sawzall.....

Note that there is steel and there is steel. ANY saw will cut corrugated
zinc/steel, or any of that bull**** on the infomercial, ANY carbide blade
will go through nails in 2x4, etc. It's really all in the blade, sfpm
permitting.

There are circular saw blades for cutting real steel plate, but they are
proly very expensive, and proly don't have the longest life, bein as the
sfpm is just all wrong from the gitgo, and this type of stuff is proly just
for field-type necessity stuff..

Also keep this in mind:
Even a top-quality dualsaw-type mechanism is complicated, and *therefore*
of questionable long-term durability, compared to sawzalls, circ saws, etc..
Infomercial/ HF quality certainly aren't going to help durability issue, but
at least with HF, you ain't payin top ripoff dollar.
Bargain or not, you gotta know what to buy from HF and what not to buy.

I didn't see this from an infomercial but H.F. email.

No one admitted so in my thread, either.
Some inneresting threads on this on alt.home.repair, as well, altho more
bickering than discussion goes on there.

Keep in mind that I routinely cut 1" thick solid alium, up to 3" thick, on a
radial arm saw, with a fine-tooth 10" blade, from HD -- a two or three blade
pack for about $30.
Be aware of the diffs in climb/conventional cutting, and a cupla safety
issues, tho. Best to to cut thick material conventionally, which in a RAS
means pushing in to the material against the stop -- much greater control,
altho you gotta make sure the blade doesn't lift/throw the material.

There is a video of a shop class instructor cutting mebbe 4 or 6" solid alum
with a circular saw.... wow.....

Also, keep in mind, when all else fails, use abrasive blades. Walters makes
wheels for alum grinding, I'm sure there are abrasive blades for alum
cutting. Just like for ceramics, etc.

Bottom line is, imo, the dualsaw is an absolute ripoff, a kind of "pointless
technology".
No one else here seems to get their panties in a bunch the way I do over all
this, but a ripoff is a ripoff, a mind**** is a mind****. All of it is an
outrage, and imo is part and parcel of the Global Economic Ass****ing.

Abrasive work well. BUT would you like to be sprayed with a shower of
hot sparks while sitting behind the wheel with a couple broken legs and
maybe an open wound or two?

Actually it does the job it was intended for very well. Cutting open a
vehicle with minimal noise and sparks compared to 99% of our normal
tools. It is also MUCH lighter than most other tools used and doesn't
require a lot of extra training to use.
About the only gripe I have with ours is the lube you are supposed to
use between the blades. When the temps climb the stuff likes to get
really sticky and makes it messy. So we generally just use some good
spray on lube, just draw the cut lines on the vehicle with the lube and cut.

saw and uses it regularly? If so, how does it hold up?

Steve needs to do some rationale A/B comparisons with a suitable
equipped/bladed circular saw.
I'll bet the results greatly favor a circular saw.

As far as abrasives/sparks go, sheeit, they DO work for a FD, they should
have spark umbrellas and fire/flash suppressors, no? A Stihl gas-powered
abrasive saws cut through 12x12 ties and 4x4 steel in railroad yards -- I'd
like to see a dual saw do that. Oh, and proly $5 per blade, as well, vs,
what, $50-$100 for a pair of dualsaw blades? Gimme a break.

Now, mebbe there are some rescue advantages to this gadget, altho I sorta
doubt it, but even if there are, that doesn't at all translate into shop
practicality or economy.

Holds up just fine. When we have used it during training it gets used a
LOT more than on a typical call. We will cut the entire roof off, do a
floor access cut, cut through the doors, cut through hoods, Whatever
might come up as a possible use on a call. For actual MVAs we have used
it maybe 10 times. We don't get a lot of calls where you need to cut for
access usually.
For the most part it does as well or better than the normal tools we
would use and it's a LOT faster.
For glass it will cut a LOT faster than something like a glass-master
tool will. With sheet metal and things like A-B-C pillars it is a lot
easier to work with and as fast as the jaws.
We have two of them, one is a newer Craftsman unit with the larger motor
and the other is one of the Duo-Saw units. Both work well as long as you
don't try to overpower the tools. Just like the rest of the gear we use.

Thanks, E.A. for your information.

I guess that I will have to spring for another H.F. 14" abrasive chop
saw strictly for aluminum. Then, try a fine toothed blade in my RAS,
too for aluminum.

I did a longitudinal cut in a 5 foot length of 3/4 inch aluminum and I
had the shop doors open and the RAS grabbed that plate and threw it
against the house about 15 feet away with an awful sound when it hit
the brick wall. I just don't have any idea of what it would have do
to my stomach had I been in the way of it. It really taught me a
lesson. Really, this plate shot out of the shop so fast that it was
very scary.

Yes, I never cease to be amazed on what has happened to the world.
It seems, no it really is that everyone is at everyone else's throat.
I am a ham radio operator and years ago, no matter what frequency that
you tuned in on, not a harsh word was ever spoken and the mantra
hamdom was help the other fellow. If he needed a part that you had,
it was his, gratis. I hate to be so negative but due to our lack of
cohesive, we are doomed.

Enough of my rambling.

Thanks for the tips.

You have to use sharp blades and replace them as soon as they start to grab.

I've got a scar on my gut that looks like a bullet wound.
