I purchased a new one Sunday and was noticing the new (to me anyway)flex shaft attachments,question is are they any good?

One way to find out is mount a tool bit and see if it moves side-to-side. (Bearing check) If it has a plastic body like the new one I got, it's crap. After exteded use, it heats up and the bearing comes out of the end. http://bbs.homeshopmachinist.net//frown.gif

Forgot to mention:
I just threw mine in my project cabnet and went back to my 25yr. old Sear's model. One of these days, I'll make a new handle for it--Metal handle that is.

Darin I have udsed flexible shafts in Dentistry all my life. We moved on to micromotors without the shaft as there was less vibration and less moving parts.
The drive shaft for a dremmel will not be in the same leauge as we used and they will overheat after a while as they are basically a wire rod greased inside an outer sleeve.That said they are better than holding a dremmel for a prolonged perion i.e much lighter to use and able to get into tighter spots good luck with it Alistair

Thanks,I already knew about the Dremel tool itself,they are light duty,but for what they are intended to do they are adequate.Heck I tried to find a 3/4" two flute endmill with an 1/8" shank,but I don't think they are made http://bbs.homeshopmachinist.net//biggrin.gif http://bbs.homeshopmachinist.net//biggrin.gif

I am thinking that the flex shaft might be better to get into tight places better than the Dremel itself,seems like it was $28.00,just hate buying total crap,I needed a router base on my new one and looked at the standard fair from Dremel,milk jug plastic is what I found.I made my own version today out of aluminum and stainless,after I try it out I'll post a picture or two.
