...I can only tell you that the tool needs to drop in farther than you describe. It's either the wrong tool or there's some obstruction in the ring teeth or inside where it needs to drop in. Is this one of the tools with a pilot pin, or is it just like a regular freewheel tool (no pin) ?

Sometimes you need to coax those babies a little with some love and stronger emotion to get them in there where they need to be.
