What grease to use on electric power tools?

[scottmandue]

I have two old Milwaukee drill motors and a Milwaukee sazall kicking around the garage remnants of my HVAC installer days some thirty years ago.

Whereas now I only use them around the house for projects every month or two however back in the day they got daily use and abuse. As you can imagine they have gotten rather crusty and clunky.

I got the crazy idea into my head to rebuild them... pretty sure I could find new cords and brushes for them, however they need to be taken apart, cleaned, and lubed.

Can anyone recommend a a good grease to use on the bearings? If you have a good link to old Milwaukee parts that would be nice too. (I haven't even looked on the Internet yet).

Thanks in advance!
