Hi Stephan,
I have the flex shaft and I was planning to use this in my CNC
driller but I have changed my mind about it. 1= it gets VERY hot so
if you are going to use it for longer time drilling you must provide
good cooling for the handpiece. I have not tested to see how warm the
shaft is though. 2=I think the best way to apply the motor/shaft is
haning the motor above your drill press. This flex shaft is very good
but is ∗limited∗ to ∗normal∗ hobby use and that means short interval
usage, othervise be prepared to buy some extra BB:s as they will wear
due to overheating.
Bengt
ps. havent had time to finish my fuser yet, but soon I hope....
