Why are people ignoring the OP's requests?
Cordless. Low buck $80 dollar range.
I've not seen a air powered cordless, please let me know as that would be sweet.
Been using electric and air powered for a while starting with porting bikes in the 60's.
Now I have lord knows how many air grinders from big to micro but they all share one problem.
A big ass cord, and a clean air supply ready on demand.
Number two not a problem for me since I pay to have air on all the time 24/7. Not the same for some so you sit while the pressure builds.
That on demand air supply is a killer for many users. Those of us who have it think it like a 120 volt plug. Not so for others.
At home if I want to kiss a bit of off something and have to fire up the compressor and wait.....puck that grab a file, good enough.
Sometimes that little weenie Dremel is just what the doctor ordered.
I have 2 of these in the cabinet for people to use. Quick relese chucks, low powered, miles of runout, not robust. Get used a few times a month.
But just the ticket for a quick fix.
Problem, they have cords. So that's $3-8 dollars to go get an extension cord and lay it. (Not to mention the OSHA violation when doing this.. trip hazard.. don't get caught there.)
Same problem with air but worse. (yes the air grinders make it up in speed....usaslly)
Cordless makes so much sense to me, the ease of use and flexibility would pay off.
Before you pounce I know the difference in working with a Dremel, NSKs and the in betweens.
Low price, cordless, die grinder type tool?
