Where to buy from sound and led 1/2" shank or ER25 edge finder, ?

Smallest I have seen was a 16mm on aliexpress, doesn't er25 go to a 15/16mm collet seen a few sets that included 16mm. I think ER20 1-13 and ER25 1-16mm

I have 2 of the 20mm shank ones. Not worth the effort... they are hardly any better than a trusty edgefinder. My issue with them is that they are so long that they run out all the time. The only way they make sense is if you have ISO40 ISO50 size taper tooling and you get then set up correctly.

The only other one I have seen was an american made one with an LED inside it. 10-12mm shank exactly like the link to Teng above

That one is ok but no ball. If mistakenly turn hanle to the other side could be damaged. But seems no other choice for now. Anyway, it's for my small mill, which i use for drilling. So i need it to find faster the edges

I have seen that one, the american, with the ball, but is expensive.

I was wondering the same thing though, if a Starrett edge finder would be better and more reliable. But as i said, on the CNC i have the MachStdMill screen set which is much better than any edge finder

How about this?
I bought the UK one above and made a push-fit ball adapter.
I used 01 Tool Steel for the sleeve, a 6mm Stainless Ball Bearing for the ball, a bit of spring wire I had laying around for the spring and spring retaining pin.
The spring is soldered to the bearing, I used a big old fashioned flame heated 1lb copper soldering iron and Killed Spirits for flux. Cleaning the excess solder off with a file doesn't touch the bearing and a quick polish on a coarse wheel cleans off any residual surface solder.
I've made the spring a little strong but it will do for now and the main bit is that it works rather well and I'm not scared of hitting the work with it ;-)

Sorry for being dumb...but what's the benefits of having the ball on the end?
