I have just had to purchase a new Badeco Hammer Handpiece for
flexshafts (my old one finally, after 25 years, gave up the
ghost/bit the dust, said adios).
I have a question, that has been at the back of my mind for these 25
years, about the speed at which this type of handpiece can be run.
Since my flexshaft motors can run up to 10,000 rpm and the
manufacturer-recommended rpm for the handpiece is only up to 5000
rpm, how can one determine and accurately control the rpm at which
the flexshaft is actually running?
You would think, after the many years of using my old handpiece, I
would know the answer to this, but how can one tell the rpm while
using the tool, and how precise must this be?
I have a Lucas rheostat (pedal), which is quite sensitive to my
control. Other than that, what would I need to do to protect the new
Thanks, in advance, for any and all answers to this inquiry.
