Dremel- how hot is too hot?
Using my Dremel 395 to cut slots in aluminum brackets yesterday, the tool got fairly hot. Hotter than I expected anyway. I've had the tool for a few years but its been very little used, never for as long or hard as yesterday.
Do these things normally get pretty warm or is mine toasted?
Thanks much.

Not sure how hot is "too hot" but I did my last one in without really overworking it. Thought it was the brushes but when I tried to replace them, they were welded to the armature. Sent it to the factory and they sent me a brand new one free. Their website does say however that there could be "up to" a $35 charge. Still cheaper than a new one. Good luck.

It'll get pretty warm when used hard for long periods at a time
As it's a high RPM/Low-Torque tool, if you are pushing on it (say, cutting metal that maybe you should be using a higher torque cutter on) it will get warmer faster....sometimes real fast

You're probably right. What I'm doing is cutting a slot between 2 1/4" holes in 1/8" thick aluminum to create an adjustable L-bracket (4 of them). The Dremel is the only cutting tool I have that is small enough. Perhaps I just need to be more patient and work more slowly.

Oh I push the heck out of mine
It takes a licking etc....
Cutting the rusted leaf spring U-bolts off the Jeep it got a little warm
-though I do now have an air cutter for that lol
But still, sometimes the dremel is the only thing that will fit
That job doesn't sound too tough though
Is it running for like 10-20 minutes straight while you're pushing on it?
Which disc are you using, the HD "waffle"?

Its intermitant pushing as the cutting disks wear down or break very quickly. Don't know what type they are, whatever it came with. I have to go buy more at lunch today as the 4 I had are history after 1.5 brackets done.

See if they have some of these guys:
They are the Heavy Duty Fiberglass Impregnated Cut-Off Wheels
Sometimes known as the HD waffle disc
Beefy
I have done some seriously crazy stuff with these
(I may have mentioned I push the Dremel sometimes)
Even if you don't use them for this project, it would be good to keep some on hand
Sometimes when you need them you really don't want, or can't run out to grab some
Although I keep a varaity of cut-offs in the Dremel box, there's always one of these already mounted
