How to remove coventry easychange chuck/toolholder

[magicniner]

Because the tool holders are on a taper they can be a little sticky, it's not always easy but turn the ring to it's limit of travel and bump the holder, I just bump with my palm and the holder will usually release.

Ok, thanks, it works. I have removed it with a small rubber hammer.
It was a bit rusty.

The System isn't really bad, only very expensive. If I see it right, its 4 times the price of a BT30 toolholder. If one have a lathe, then he can turn the taper to 10° from a BT30, who have the same max Diametre. After that, it needs the recess for the clampballs.
