Advice on toolholders

[m_c]

Is it just the light/reflections, or is the taper on that toolholder look like somebody's sanded/filed it?

I've got the easy change system on bench top mill, and my holders all lock in that tight, I usually have to use a screwdriver to break them away from the taper to get them out.
Could it be the ratchet mechanisms not working correctly?

I'd perhaps give Coventry a phone, and see what they say. It could be as simple as the spindle adapter needing stripped and cleaned, although I have no idea how they separate.
