Hard for me to believe keyless chucks would grip a bit tightly enough to
work with it.

Are keyless chucks OK with hammer drills???

Never had any problem w/ my Milwaukee one-piece keyless. I would not
say the same thing about some of the two-piece keyless chucks I've used
(nor can I say anything firsthand about how well other than Red ones
work )...

Why would you want to buy anything but a Red One? G

I agree. My Hilti tools are AWESOME!

Not that hammer drill is my primary use for it, but my Dewalt 18v
cordless has never dropped a bit in hammer mode. Their keyless chuck
has a feature which locks it with a slight twist after tightening.

Get a drill that uses SDS type bits. They snap in and can't slip, and it
seems to me, that the SDS Hilti and Bosch drills I've owned, transfer more
punch to the work than any non SDS Milwaukee, Ryobi, Makita, or Dewalt I've
owned

I own 2, a small 3/8" chuck and a bigger SDS type roto hammer.

I would never buy one with a keyless chuck.

Agreed - I can't think of a single time where I would have found a hammer
drill useful; a good SDS makes the heavy stuff easy*, and a conventional,
lighter-weight rotary (and my DeWalt wasn't expensive, yet it's seen a lot
of use) seems to handle everything else.

* except when a chisel bit binds in a wall and I have to leave it there
while I drill around it to free it - grrr! :-)

I suppose I might talk myself into a cordless rotary too sometime, but
probably not in the near future (I prefer having constant power and not
messing with flat batteries, even if it does mean running a cord)

cheers

The answer is yes, no, definitely, and maybe. I would say they are okay,
but still, there is more chance of coming loose than a keyed chuck. Some
bits have a round shank, and some have a triangular shank. The keyless will
definitely hold better on the triangular ones, but once it comes loose at
all, it's wallowing out the metal inside. My recommendation is to use it
for 3/8" bits or less, and bigger than that, go SDS. SDS are so simple, and
reasonably priced, too. Plus, you can get points, chisel tips, different
"bits" for it.
