I bought a box of assorted burrs at a garage sale. There were two Foredom
handpieces in the box, one of witch I have not been able to find anything
about on the web. The mystery handpiece was in an original Foredom plastic
sleeve labeled "HANDPIECE NO. 7". As far as i can tell there is not a
conventional collet or chuck. The nose of the handpiece tapers to a pointed
snout with a aprox 7/64" hole.
If anyone has any info on this I would appreciate it. As I said google does
not even tell me that a #7 handpiece exists.
What is it designed for?
Is it discontinued and if so why?
Is it safe to use and if so how?
See a picture of the handpiece at:
if you go to foredom's site you can download a pdf of their current
in it there is no no. 7 handpiece. however, there is a no. 15
handpiece, which is a teeny tiny jackhammer (more or less). it also has
a picture of the pionts used by that handpiece. think they might fit
foredom does not make all of the handpieces they sell. I have a very
nice one made by some outfit in germany, branded foredom, but obviously
not their manufacture. the no. 7 may be one made by some third party
who went titsup sometime in the past. it would be interesting to find
out the history of your mystery handpiece. you might give foredom a
call- somebody there may have some information for you.
OK, found it.

if it's anything like the one I have, and I think it probably is,
you'll find it an absolute joy to work with- as long as you stay within
it's fairly narrow performance envelope. it is for delicate work at
high speed using sharp cutters on non abrasive materials. since the
collet is machined directly into the shaft, it will run very very
true..... note however, that the collet in not serviceable- if you
damage the collet the handpiece is dead. so don't try to use it for
hogging out, don't run cheap bits in it and keep the collet clean- and
you'll figure out that cleaning that collet isn't easy, either.
nice score. have fun with it...
