Pendant moter Vs Micro moter


#1

im sure this debate must have been played out many times on the
Forum before but i would like peoples oppinions on which drill i
should get and which brands are better. i’ve done a fair amount of
e-research but i’m just aftersome users views.

i hadn’t even considered a good quallity micro moter untill someone
suggested that to me.

i am after a moter that will be versitile and addaptable. i do a fair
amount of stone setting so slower speeds would be better i thought.

thanks for you’re help on this…

Most important for stone setting is full torque at all speeds. If you
do not have full torque at low speed, when you start the burr catches
amd jumps out of the setting and usually causes damage to the
setting. Took me years to discover the problem as I was using a
Foredom “cc” model.

I have a micromotor and several regular flexshafts. Micromotor is my
favorite, use it 90% of the time. Smooth and quite, it is always a
pleasure to work with. I can use foot control or set constant speed,
it has forward and reverse, does not get hot, hand piece is very
comfortable.

Chris,

Author of the “Making the Most of Your Flexshaft” book here, so let
me address your question.

As a side note, there are only 200 copies left from 5000, so if you
want a book, get one soon.

By “pendant” motor, I’m assuming you are referring to a hanging flex
shaft.

It’s a fair question and honestly, it depends on the work you do.
Personally, I use both. I have a Foredom TX which is very versatile,
allows for a #30 Jacobs chuck for tiny drill bits up to heavy carbide
burs. The TX and the newer SR reversible is great for lower speed,
heavy torque, perfect for stone settings. Why use large and gigantic
carbide burs? Recently I was drilling out acrylic for making a die on
for a hydraulic press. I could have hand filed the whole thing, but
my Foredom TX and a heavy duty cylindrical bur chewed through the
plastic in half the time.

The micromotor on the other hand is another great tool for my bench.
Even in the limitation of the handpiece using 3/32 inch mandrel
(sorry, we are still backwards in the US), the speed needed for
polishing applications, like the radial bristle disks which need
high rpms is quieter and more gentle on my hands. I have the option
of setting the speed once and knowing that with all the polishing
options, the rpm will be high enough for polishing. With this
operation, it doesn’t need the torque. The handpiece is very easy on
the hands, delicate, great for making perfect slices through a bezel
for cabochons using the slim separating discs. Most accessories will
accommodate the micro motor handpiece.

Deciding on which one to buy is sort of like the car you drive. Do
you haul stuff where you need a truck, or can your sedan pretend
it’s a truck and be able to jam stuff into it.

If I had to choose one, I would go with the hanging flexshaft. It’s
cheaper, and you can do everything with the flex shaft that you can
do with the micro motor. However, if you are experienced, set a lot
of stones, then yes, a micro motor will work great.

Best,

Hi Chris. If you can afford it, get both. I’ve gotten so I couldn’t
get along without either one. I’ve been very pleased with my Gesswein
micro motor. It was $300+. And of course you can’t go wrong with
Foredom.
