Is this what you're looking for? A bit priced so you're probably best just getting a donor like this 247. https://www.ebay.co.uk/itm/256805393040

I have no pride. The subseconds pivot was broken when I got the watch. I filed it flat at the point in the arbor where the diameter changes. Chucked it up in the lathe and turned a center for drilling. Using a carbide drill bit, I proceeded to drill a hole. I was making progress and should have stopped, but I didn't. The drill broke off. Not the first time for this to happen. I considered making a new arbor from scratch. I have a mill and a precision indexed rotary table along with some cutting wheels that was part of a recent lot buy. I actually cut a pinion on brass stock just to see what the teeth profile were. I think I could do it, but did not know if my cutting wheel was HSS or something else, so I did not want to destroy a wheel on a fools errand. My metallurgical skills are weak to none, so the prospect of annealing, cutting, hardening seemed like more effort than it was worth even though it would be another great learning experience. So...I set it aside for now. -

I bought mine off ebay, originally i used them just held in my hand, until i got the proxon drill that solved the excess runout that basic dremmel tools have. It was Nev that told me about dentist slotting disks... tbh it's pushing the limits of what a 1mm Swiss screwhead slot should be ( 1mm screwhead not screw thread) , which is more like 0.1mm .
