Foredom knockoff


#1

Hello,

I bought a foredom “style” flexshaft from Grizzley Tool about a year
ago and it works for what I need it for. I do have a question
though… I am thinking about buying a foredom hammer handpeice and
was wondering if it would fit this? Has anyone seen one of these? The
handpiece it came with looks like a Model 30 foredom.

Thanks
Steve

Dear Steve,

In my experience there are very few Flexshaft systems that have
different shaped shafts. And it is the shaft that dictates the type
of hand piece that can be used. For instance, the Foredom H series
has a square shaft and will only work with hand pieces the have the
"H" designation in their description. All others, that I have seen,
have a round shaft with a “fin” at the receiving end of the shaft.
This fin fits into the hand piece and is what drives it (the hand
piece). Please keep in mind there are a lot of products similar to
Foredom so I could be off but I doubt it.

Now, all this being written, it’s harder to match the off brand
inner shaft to the motor than to a hand piece, so when you purchase
an off brand flexshaft do your homework on replacement parts.

I hope this helps.

I haven’t seen the unit you described, but have seen a similar unit
sold by Harbor Freight. My guess is the one sold by Grizzley is also
made in China, so is probably a direct ko of Foredom without
anything being held to close tolerance. The unit sold by HF will
accept any other the Foredom type quick disconnect hanpieces.

Steve, Hammer handpieces SHOULD fit the shaft/sheath combination you
are working from. Just make sure the blade on the output slides into
the slot of the input. And now, THE BAD NEWS. Keeping rpm’s low is
key to your hammer handpiece surviving. You should not exceed 5000
rpm going into a hammer handpiece. The mechanisms that translate
spin into impact are delicate, and burn out at high speeds. On a
budget, put a stop-block of some kind on your foot pedal, to prevent
full depression, or “stepping on it.” Have a benchtop dial rheostat?
Keep it low! IJS sells a combo foot/dial unit that may be the
ticket.
