Penetrating oil. It's surprising how much it will help - the best war story with it was a morse 6 adapter on a morse 5 tool I bought from ebay.. REALLY jammed - tried it first with force like you describe and didn't succeed. Some penetrating oil, some heat, let it soak for a day, and it just came off with quite limited force.. It was clearly visible how the purple oil was on all the inner surfaces of the morse taper..

Best penetrating oil is the liquid penetrant used in non-destructive testing, looking for cracks.. Available in spray cans at welding supply stores - you don't need the developer.

The drill is toast, so you can destroy what's left of it. Often the shanks are soft. Can you drill and bore out the remainder of the drill's taper?

Are the reduction sleeves hard?

If not then they've probably all spun and galled together. It may well be a write-off, unfortunately.

Scrap it an move on. you could try heating it a little, immersing it in kroil or something similar, but the time you take to do it is worth more than the parts damaged, and even when you get them out they wont be right. ( twisted, bent, gauled)

We have some of that penetrant on hand at work... I will give it a try and leave it for a few days. Randy

So, did you get the parts apart?
