They just updated their site. No idea about them at all other than Modded listed them. Since they were listed before without issue, new links are:
Standard: https://www.brw.ch/en-CH/rego-fix-collet-chuck-er-339000

Can’t speak to the others mentioned as they don’t appear to list runout specs at all. Let alone if they are an average, AQL, etc. Although, I’d bet good money they are better than the “Amazon specials” you get that can be as bad as relabeled scrapped goods.
The others I am aware of with measured collets since my previous post here are Haimer, and Pioneer. Kennametal does too but they appear to be a lower grade than the standard used by the others (DIN 6499 Class 2, 0.015mm/0.00059"). Haimer is all at least “UP” and Pioneer has “PG”, “UP”, and “EP”.
Techniks appears to now be part of Eppinger along with Parlec. They seem to have the same strategy as before a “standard” unmeasured grade and a AA or “UP” grade at a higher price. Don’t know if after this Techniks are still SYIC sourced.
Appreciate the @ and link Will.
For those that want more on collets here’s some other threads I know of (was involved with/rambled in):
And the previously mentioned one by will… Also, the last one goes a bit off the rails.
Short version in general is:
Runout effects chipload, higher precision collets have less runout, therefore more consistent chipload coming out to less waste of chipload/feed and better cuts. Matters more when your chipload gets smaller as you have less wiggle room (harder materials, smaller tooling, deflection limited, etc).
Let me know if there’s something I can help with.
