Did anyone try both Plain Bearing and Ball Bearing drill press chucks and can share his
thoughts? Are BB chucks really worth the difference in price?


Thanks,

My favorite chuck (and I have been through a bunch) is a Jacobs 3A plain chuck.
It's real close to dead nuts on, doesn't slip on bits throughout its whole
range, and just plain works great.

Supposedly the 16N (the ball bearing equivalent) tightens down better, but I
always - ALWAYS - turn the key in all 3 holes, and the bits don't slip for me.

I'm confident Grant is quite right.

And this is really not a response to your question at all!

Far and away my favorite chucks are the 1/2" Keyless chucks. I scored an
Albrecht at a flea market, and have purchased two new Jacobs versions
from J&L when they are on sale. I'm sure they are not the end-all for
everybody, but it's a very rare moment when I switch back to a keyed
chuck, or even think about it.

Except when you need to run a left-hand drill bit (if your drill
press happens to be reversible). For that, most keyless chucks will
release very quickly under cutting load.

--- Black Holes are where God is dividing by zero ---

The up side to a BB chuck is that the actuation is MUCH smoother, the down
side is that for a given size they are about %50 bigger in diameter. I have
both and ocassionaly use both, my 1/2 is BB and I LOVE it, my 5/8 is plaine
and it works... Like Grant I was taught to ALWAYS use the key in all three
holes and even do that on the BB..

If you have a Milling maching you'll probably use a much smaller chuck for
the under 1/4 inch bits and then use turned shank bits and a collet on the
bigger ones... Long ago I used to think turned shanks were for people who
couldn't afford a big chuck (or were using an oversized bit in a wimpy hand
drill) then I got my first mill drill with collets and realized what a
turned shank was all about... Now on my BP with power downfeed I KNOW what a
turned shank is for :-)

FWIW I can usually get by with using a collet even on the smaller bits, just
depends on how much you want to 'spring' or compress a not quite exact fit
of shank size to collet...

All my better bits above 1/4 have turned shanks and I even have a few of my
bigger bits (1 inch range) in MT for the tailstock on my lathe... It's my
lathe that I wind up using chucks much more than I do on my BP. Some day
I'll be rich enough to afford a better lathe with collets for the tail stock
too. :-))

Yes, although they are bigger, as was pointed out, which can sometimes be a
problem.

The aim of untold millions is to be free to do exactly as they choose
and for someone else to pay when things go wrong.

In the past few decades, a peculiar and distinctive psychology
has emerged in England. Gone are the civility, sturdy independence,
and admirable stoicism that carried the English through the war years
.. It has been replaced by a constant whine of excuses, complaints,
and special pleading. The collapse of the British character has been
as swift and complete as the collapse of British power.
