Something like this, with TorqKey written on the shaft (I think one company makes them for a number of brands)?

If so, does yours have a tiny bit of play in the shaft when you push / pull the bit towards / away from the handle?
Just dropped mine while doing a bit of fettling and my OCD is going haywire!
When I can be arsed to go upstairs I'll have a look for you ๐
The bit is pressed into the shaft and sometimes have play, sometimes the bits fall out completely and need gluing back in. Hope this helps.
Ah, I misread and thought you had play between the shaft and the handle. The bit on my 3 all pull out so you can switch between different sizes (4, 5, t25...)
@simondbarnes yeah its the shaft that has a bit of play.
@wheelsonfire1 its the actual shaft that has half a mm or so play in it rather than the bit itself. That looks solidly glued in there with epoxy or something.
Mine have all got a bit of play in the shaft
@simondbarnes legend, thanks for checking!
A bit late but yeah the Bonti has a milli or so up n down play in the shaft with a little clunk, I used a soldering iron on the fixed bit on mine to heat it just enough to melt the glue and pull it out, then I glued a little magnet disc inside so I can change bits like the Ritchey one.
