New Dremel cordless

depends on the RPM... I tried my corded (up to 15000 RPM I think ) dremel on a model once...... ONCE....

with a soft felt tip it dug right into the plastic and I had to break out the putty... I would find out the RPM and go with the slow one... the slower the better....

I have found my Dremel works best on styrene WAY under the minimum rpm of a cordless tool.
Just my two pennies, but you might be better off (if plastic is the reason for the purchase) to spend a little extra and get a variable speed control to go with the Dremel, because there will be times when only a couple hundred rpm are really needed!

I personailly would not buy the cordless due to speed adjustment which is nearly none.Digger

You definitely need speed control if using a Dremel on plastic. The high RPM just melts styrene. I don't know the minimum RPM on the cordless, but if it's high then it's a problem.

I have the mini might dremel and have no problems at the low speed. Just pay attention to what you are doing and use a good touch.

Thanks for the replies all. I think I'll forget about a cordless and just get a variable speed control add-on for my corded dremel.

Thank you,
