Foredom hammer handpiece warming up


I purchased a used hammer handpiece, the 15, a while ago for a super
price. I got a diamond tip for it and have been using it at the
suggested lower speeds. After using it for 2 minutes the handle gets
warm and it does not punch like it does before. It kind of skips a
hammer punch.

It does not have a duplex spring. Does anyone know what might be
wrong with this tool? I am assuming I might have to buy a new one,
but I also thought maybe this is just how the piece works or can fix

Any feedback is greatly appreciated.

Thank you,


It sounds like you might have a worn out cam or cam pin on your No.15
Handpiece. Either way you can send it back to our Repair Department
at Foredom for a free estimate for cleaning and repair. Please
enclose your name, daytime phone #, return shipping address and a
note explaining your problem with your handpiece. You can send it to

You might have set the speed or power UP TOO darn high. Lessen the
"pounding" to a lesser notch. Experiment with the various settings or
turnings on the gnurled lever. Why didn’t you get a Duplex spring? My
"Bedeco" Hammer has a duplex spring, and it works wonders for me. All
of the insides are made of steel and not one piece of plastic causes
any heating up to the user. (moi) Another pointer for you, slow down
you motor speed too!..Gerry Lewy!


Several of the US suppliers have repair services, and there are a
couple of Orchid members who repair handpieces.

Either the internal components of the hammer handpiece are worn, or,
less likely, there is too much lubrication that is acting as a
conductor to transmit the heat to the exterior of the handpiece.
Usually it is cost effective to have them cleaned and re-built.

I’ll second this one. Foredom is an excellent company.

By the way, if you are a student at any college, highschool, adult
ed, and you purchase a flexshaft ANYWHERE, save the receipt and they
will rebate you 10 percent of the cost back to you in a check.

The person to contact is Mike Zagielski. He is the nationals sales
manager and is the kindest and very knowledgeable.

If you contact him, tell him you saw this on Orchid from me.

Jane, I don’t know what could be wrong with your handpiece. I have
had mine for about 7 years and have not had any problems with it. I
too would welcome any comment on this.
