Square holes on aluminum.... how do you do it?

I wonder if there are any high speed dremel type tool that will withstand heavy-duty usage? I used a regular type for this particular time. Well... it got awfully hot. Also locking mechanism jammed so I had to take it apart and fix it. Maybe something like dentists use?

I am thinking a compressed air "Dremel" would be tougher and last forever. Have you been to a dentist lately?

Yes, in Spanish I have always called those saw blades "hair blades" because they are so thin. That arc is smaller and gives the user much better control. Mine has a wider arc with longer blade and more reach. It allows reach into deeper places but is also more cumbersome to use. Maybe I sould get a smaller one for finer work. In fact, I could use broken blades from the bigger one.
