just a quick one about the 1-1/4-inch 1/4-inch shank bit flush trim bit with top and bottom bearings that gets unruly at full revs.
took off the end bearing and allen screw rev'd up to 23,000rpm and no problem
with bearing back on all hell breaks loose
my guess is that the ball-bearings are piling up on one side and cause things to get eccentric
I may try some bearing swapping if I'm really bored
I sure wish you'd discover punctuation.
Reminds me of the tales of Archy and Mehitabel.

Interesting. Sounds like a bad bearing. It could also be that the hole in the bearing is larger than the screw (i.e. it's not the right bearing for that bit) which is allowing the bearing to shimmy around.
It could also be that the hole for the screw is not co-axial with the bit, forcing the bearing to be off- center.

Hey, he's got a period, a comma, and a 'postrophe in there. How many more punctuation do you want?
John
visual inspection dont reveal anything will clean the bearing and apply some light oil may be a crappy bearing or simply wrong one for this application
there should be no spacing between ball-bearings or it should have a bearing race or something to keep them from moving outward and/or together
not sure the make it has yellow paint
A teacher asked his students to punctuate this sentence:
"Woman without her man is nothing."
The men all wrote, "Woman, without her man, is nothing."
The women all wrote, "Woman! Without her, man is nothing!"
Get new bearings at the Auto Store. They have them or can order from their supplier. We used FAGG in Disk Drives. Long lasting. Sealed.

Take the bearing off and screw back on the screw. See if it runs true.

I picked up one at Harbor Freight.
You get two brg, screw and bushing as a kit.
Outa stock? Buy a complete bit for $5 and throw away the cutter.

VIPER if I remember correct.A BORG item years ago.
