When I do composite work (fiberglas, epoxy, etc) I only use disposable HF die grinders for my sanding tasks. The last thing you want to do when laying up structural composites is to contaminate them with any kind of oil, so I buy them with the express intent of running them without oil (something I'd never do with a "good" tool), knowing that I'll just toss & replace when they finally lock up. There's a time & place for just about everything <g>.
Yes, there's a place for everything.
