Greetings and Salutations.

I wonder if anyone here has any experience with a curing/paint drying cabinet?

there are a couple of well rated units that can be set for specific times and temperatures.I believe that they are used for plastic models as well as brass models and other practices with scenery such as making tunnel portals out of plaster and walls of various kinds. 
it is basically an integrated warm air convection system which circulates warm air around the model of choice.

A post asking about motor tools got me thinking.  It has been a while since i looked into bits for my motor tool.  I dont use my motor tools as much as probably i should.   So i was wondering if perhaps there are bits that i dont think about of know about or uses i don't take advantage of?

So what are the best bits you have for your motor tool and what do you use them for?
