Battery pack opening method with Dremel rotary tool.

[Tuomas]

Thanks, Tuomas,

I have the EZ-lock mandrel and the metal cutting wheels but I hadn't realized that Dremel made a type for cutting plastic. Another tool for my arsenal, I've added them to my Amazon shopping basket.

You're welcome.
Those plastic cutting disks work specially well with little harder plastic types. Like ones in the motorcycles etc.
But they work nicely with softer ones too, if used lower rotating speed.
Good thing is that those lasts very long.
