   Definitely keyed. Keyless chucks don't take as much abuse and don't tighten as tight.
   My 2 cents,
   John

   *See the article "what's the difference" in this months' FHB and you'll know. Don't buy a hammer drill. If you are planning to drill holes in concrete or masonry get a rotary hammer. There is NO comparison, once you try one there's no going back. Joe H

   *That's interesting Joe; what I got out of the article was that if you don't do a lot of heavy drilling in concrete, just the occasional tapcon or whatever, a hammer drill is the appropriate choice. I absolutely love my Milwaukee 1/2" KEYED CHUCK hammer drill. It's perfect for my needs. Keep the overgrown monsters--I'll rent one when I need it.

   *I guess I was a bit opinionated there.....IF you're going to use it for drilling concrete, and I mean a 1" hole 6" deep or more, you wanta SDS or something bigger. A small one like a Bosch Bulldog is no bigger or heavier than the Milwaukee, and it will drill those 6" deep holes one after another. I have a 1/2" Milwaukee hole shooter & an old Hole Hawg arm breaker, but I love that Bosch SDS for masonry. Joe H

   *I have the milwalkee with the keyless chuck and it works great 95 percent of the time but it will slip under heavy use, and is also sometimes hard to loosen the chuck when i tighten it too much.

   Would you buy the keyed or keyless version of the magnum hammer drill? I am an infrequent user and I my main objective is buying something that causes me no problems. Thanks.
