Bought a Used Albrecht Chuck

[DR]

I recently sold my two Albrecht 1/2" chucks because I got tired of the hassle of loosening them when they self tightened beyond hand force under heavy load. Out of frustration there was always the temptation to use a pipe wrench.

And there was the issue if them loosening under reverse rotation if used to hold a tap.

Anyone that can't figure out how to use a Albrecht chuck should maybe take up knitting.

Most people use ER collet holders for holding drill bits in CNC machines.
They have a backstop to hold the Z in place.
An Albrecht chuck is totally variable where the tool is in the Z.

Obviously your mileage varies from mine. Besides, “most people” don’t run machine tools.

Thanks for the replies!
Bought a Shars R8-JT6 collet (23 bucks with shipping) it has .0007 run-out and with the used Albrecht Chuck, holding a gage pin it has a total run-out of .001.2.

Absolutely . Such should not be allowed to own any precision tooling. :-)

I know how: don't run it in reverse. My keyless Kawasaki chucks will rum in either direction of course.
