Spring bar removal tool problem

[SKILLEFFECT]

Hello guys,

I recently bought a spring bar removal tool from eBay that came with several needles with different sizes. It is exactly the same as Bergeon 6825, however I can't seem to fit the needle in the springbar.. The space to access the bracelet springbar is smaller than the needle width.. This in a 126710 BLRO.


There's a pair of needles with supposedly 1mm that I can fit inside the gap of a 16610 SUB to access the springbar however it is super tight, it feels as if I need to force it a little bit for it to enter. On top of that it doesn't sit flush on top of the spring bar, feels like if I start to pull it it will slip at any moment and the spring bar will fly across the room..

Am I doing anything wrong or something? Picture of the different needles in attach.

Thank you!
