Keep in mind that any and all steps described below could hurt you financially, physically or even morally if done improperly. Always follow the instructions of tool manufacturers and apply the most rigorous logic to situations.

Jack's answer makes sense. I have done something similar to clean vacuum hoses, and it works. One additional suggestion would be to use a grease cutter product as a second stage after the dish soap. They sell stuff like this at automotive and hardware stores.

Start out by soaking the hoses in hot water and blue Dawn dish soap. It's the best for dissolving grease and I'm not affiliated with them in any way. Then you'll want to thread a heavy string or rope through the hose and wrap one end around a big rag and pull the other end so the rag gets pulled through the hose. You'll have to do this a few times to get rid ...

This worked extremely well. I ...

I've had this happen when hammer drilling as well and I put the drill in reverse and stuck the drill back in one of the holes. This was able to loosen the hammered death grip the chuck had and I could easily remove it. Although, if you do it too long it might remove the drill bit from the chuck.

Try the following "low-intensity" method: Apply WD-40 (or other similar "penetrating" lubricant?) generously to the maw of the chuck. With a small hammer, gently tap different points on the chuck's surface, from different angles. Nothing that would cause a dent, just slight mechanical vibrations. Might help lube seepage. Wait a while (an ...
