what can I do with a weak-a@@ motor?

I bought a grinder from Ace hardware for $9. It was marked down from $20. I thought it would at least be good for putting a final edge on a tool or buffing or something. I figured at $9 it was worth playing with.
I brought it home plugged it in and tried it out. It has absolutely no torque or power or anything. If I somehow attached a brand new endmill to the end of the shaft of the grinder and turned it on I could probably stop it with a gloved hand. That's how weak it is.
Is there a shop tool that uses a motor that spins fast with no load? The thing indicated pretty dang straight and if it had some power it would be the best tool in the shop.

Perhaps a sensitive drilling machine?
Small drills need plenty of speed and don't take too much torque.

I think it might be strong enough for that. I might put a very fine wheel on the other end for honing cutters. But I didn't think of using it for a drill. Thanks for that and problem solved.
Now I'll have to buy the universal pillar drill kit from Martin Models

I checked the motor's info and it is a terratek 6" bench grinder #PBG6.
120B-60Hz 1.1A
Spins at 3450.
Could I use it as a tool post grinder? The shaft only has .001" TIR and it has the speed.
I don't think I would be grinding so heavy with it I would bog it down so I think it's worth a shot. And the shaft is threaded so I can make an ID grinder attachment.
Any comments on this idea?

Unless my maths are out, I make that motor about 125Watts about 1/5 HP !

It would spin a small chuck for a sensitive drill though.
