It's a blade holder that fits in a multi-function oscillating tool. The
holder then accepts a 3-inch saw blade plus various spiral-toothed blades.
With this tool and blade in place, the result replaces a coping saw and
other tools for detail work.
This is a fairly new tool and prices are all over the place (Rockwell,
Bosch, etc.). The best price I found was from Amazon for the one made by
Dremel, a few pennies less than $20.

I experimented a bit and found the tool to do MUCH better than my ham-handed
prior attempts at molding coping.
In what brand/model Twitchy-Tool did you try it in?
I just bought a HF variable speed and gave my single speed to my son.
I hear the variable speed has a universal mount, but I haven't tried
any non-HF attachments yet.
Oh, yeah. The Harbor Freight Miracle Multifunction Mandible Oscillating
tool. Since I couldn't justify a $300-500 Fein, I stepped down a notch to
the $14.99 HF offering. I've got three of them now; buying the kit is
cheaper than buying the blades that come in the kit separately.
I'd be surprised if bits from other manufacturer's DIDN'T fit. HF seems to
be following the Gillette business model: Give away the razor and sell the
Read what you wrote. You may be right, but your post doesn't make your
point very well.
If HF wants to give away the tool so they can sell you the blades, why
would they make it so the tool works with other manufacturer's
attachments? Seems like they'd use a proprietary mounting system so you
would have to buy *their* attachments.
I'm pretty sure you can't use a Schick blade in a Gillette razor for the
very "business model" reason you brought up.
You could switch blades with razors back in the day when all that were
available were single- and double-edged razors and blades... not counting
I'm sure various MBA types have determined that making cheap attachements
is, to some degree, counter-productive. I suspect because if, say, Dremel
began marketing a blade that would only fit their tool, it wouldn't take
Bosch or HF ten minutes to jury-rig something to compete. Meanwhile, Dremel
would get flogged for "non-standard" stuff.
First, Dremel is a division of Bosch, so I suppose what fits one will fit
And, yes, I'm almost certain you can use a HF blade in a Dremel (or Bosch)
or Fein or Rockwell or anybody else's tool.
Buy a HF blade. Try it out. If it doesn't fit return it for a full refund.
I don't have any other brand than the HF, so I can't test their claim, but
the text for the 2 attachments shown below say that they fit a long list of
manufacturers, including Bosch and Dremel.
It was my (unsubstantiated) understanding that once HF changed from the
slotted-hole mounting system to the round-hole mounting system, their
attachments became universal.
What's strange is that most of the blades that they show on their website
show the slotted blades, but all of the accessories that came with my
variable speed model (purchased in January) have the round-holed mounting
system, even the same blades that show as slotted on their website. I
wonder if they jut haven't updated the images on the site yet.
This one, even though it says it fits other brands, shows the slotted
mounting system. I think it's an image issue and that all of their
attachments have the round holes now. I'd have to swing by a store to

The design is much different, not that it matters to me but it is way
different. They fit the same on my HF with no problem. So I guess they are
going after more business. My only gripe is I would like a good hacksaw
blade for cutting metal. The bimetal just does not do it for me. For little

I read that before I bought my last HF blades, too. Useless. Bosch
does have a disk that fits over the blade mandrel to make it more or
less flat (small bumps, intended to grip the blade apparently). Using
that, anything, sorta, fits but it doesn't hold the blade well and
there is nothing to really center the blade. I ended up using it
yesterday because the new Dremel blades don't fit the Bosch, either.
