Do you mean like a tpms valve stem? The ones i had were best case scenario i guess just the standard style valve stem.The hole is roughly the size of the valve core all the way through, but my beads were jamming right away aswell.The vibration definitely helped speed up the process its worth a try an oscilating saw sounds like a good idea if your saw has the guard dont have to worry about damaging the valve stem. However i found more vibration was better so still may wanna try a high speed drill if the saw doesnt work.

@@diyoutube6061 I dont think so. There's no sensor. just a finer orifice in the bottom. Maybe it makes it tolerate more pressure or something

Not that simple. Doesn’t always work a lot of the time both beads will unseat together if the tires stretched. If you’re gunna run beads instead of a proper balance why bother going through all the hassle, especially if you mount by hand tools without access to a machine.
