Bet this ruined someone’s day

Found this in a big lot I got at auction. That’s a 5/8” drill. Glad it wasn’t me.

The sword, in the stone? I would think heating the aluminum would loosen the grip, and you could back it out?

It looks like a well mounted arbor. Ouch!

At least he'll never lose or mis-place it .

From the looks of the right edge, he already tried the BFH technique - So you can eliminate that, and save time :~)

Just back that screw out on the side. That should release the drill

Seriously though. I hope you take the challenge and remove it. Nothing a vise pipe wrench and a long cheater bar won’t fix. Along with some tap magic for lube.


Cutting oil is my blood.

Experience IS the best teacher!

Can't be that hard to remove. Maybe weld a bar onto the shank of the drill and use a BFH or press.

Coefficient of expansion for aluminium --> 21-24 x e-6 m/(m °C)
Coefficient of expansion for steels --> 11.3-12.3 x e-6 m/(m °C)
Coefficient of expansion for stainless steels --> 10.2-17.2 x e-6 m/(m °C)

However else you tug on it (as well), basically @Aukai has got it exactly right!
HEAT!

Toss it in the oven at maybe 450 degrees for a bit then quickly try to remove it.
