Jump Ringer System


I’ve been making silver chains now for a couple of years, and I’ve
realized that it is time for me to finally be making by own rings!
I’m interested in buying the Jump Ringer System, but have one
question. The I’ve seen says that you need to use a
Flexshaft handpiece/motor. I’m trying to minimize my costs right now
and was wondering if it is possible to use the Dremmel tool that I
already have.

Thank you very much!

No, it has to be a flexishaft w/a type 30 handle, I believe…went
through that myself a few years back…it has to deal with the saw
attachement fitting onto the end of the flexishaft. It won’t on a

Hello Carol,

No, the Jump Ringer System requires the use of a flexible shaft
machine to drive the blade that cuts the coil into rings. The model
we recommend is the Foredom model S.

The reasons we designed it to operate with this machine and not the
Dremel is that while the Dremel will produce the necessary speed, it
lacks the power of the Foredom. Its motor would be stressed and
would burn out . The Foredom will give you a lifetime of service for
this use and many other uses while the Dremel will not. In addition
to this, the Foredom hand piece has an infinitely adjustable Jacobs
chuck while the Dremel uses collets. The Jacobs chuck allowed us to
design in a larger diameter shaft on the blade arbor for greater
strength. There are good reasons why professional jewelers use
Foredoms and not Dremels.

I hope this fully answers your question. My father taught me many
years ago:

Thanks for the kind words!

I need to make one correction though; my ISP change it’s name, my
address is now: @Dave_Arens.


there is a koil kutter made to fit a dremel. It is available from a
Company in tucson, az. It works at least as well as, if not better
than, The jump ringer made for the foredom and only costs $ 70 to
80. I have both types and recommend the koil kutter to my students.

The Koil Kutter uses a Dremel, and it costs about $70 plus shipping.
I’m considering getting one for myself because I do cut so many
coils. Here’s a tutorial on its use (and the coils look crookedy
after the cut because they move when you take the lid off the cutting

And here’s a couple of old Ganoksin post about how to get the Koil
Kutter and what it does:

Hope that helps.
