When I see folks attempting or proposing accurate production-type
performance with HF tools, my initial response is Are You Serious?

I know in some minds cheap is better than quality, it replaces quality with
imagined performance and value.
But.. some RCMers have had moderate/good success with some HF products,
usually combined with a lot of time and effort.

I think it was Bob (La Blond yumabassman) that achieved a certain level of
sucess with high speed milling of mostly aluminum with HF's flex shaft
rotary tools.
He was making molds for fishing lures on a CNC'd mini-mill.
IIRC, the spindle speed was about 15k RPM.

I don't know how the new Goog groups search works anymore, I can't even get
postings to display, and I dunno another way to search RCM archives.

I believe there were at least a few others that have utilized major brand
name laminate trimmers for high speed spindles.

Harbor Freight's 1/4 inch electric die grinder was tried

So you actually tried a Horrible Fright die grinder (showing a complete
lack of good judgement), and damned a brand-name quality-controlled
laminate trimmer without actually trying it, because in your judgement
they are exactly the same?

From here where? Go small. "Smaller tools, smaller runout" seems
reasonable.

Your reasoning is flawed. Better bearings, smaller runout. Proper
collets = no need for shady adapters. Or you buy tools with the proper
shank size for a collet you have. And not from HF. Not any of it from HF.

"precision rotating machinery" and "horrible fright" only go together in
the manner of: Don't buy "PRM" from "HF"

Likewise, if you want a decent "thing that resembles a Dremel tool"
neither Dremel nor the cheap knock-offs are a good bet. Crummy bearings.

I suspect from your choices thus far you are beyond help. Have fun.
