I bought a used milwaukee 5351 hammer drill and can figure out the process for changing bits. I've unscrewed the head (counter clockwise) seen all of the internal parts there but can't get the existing bit out. Can you help
The parts are obsolete to replace in the most case if it will come out the driving guidance is often worn in the bit holder and a
lockup will repeat soon

The spade bit sold with the hammer drill was actually too large for the hammer drill. We found that the spade bit had over heated (not from overuse or heavy use as only two ladies were using the hammer drill) but because the bit was too large it put too much weight on the drill. The bit had to be removed from the chuck using a hammer and force causing a bearing to come out and the chuck now needs repair. Solution repair the chuck on the hammer drill and buy a lighter spade bit. Then continue jackhammering the cement out of the shower cubicle.
SOURCE: my drill bit doesn't remain secure in the chuck of my drill.
grind bits shank in a triangle to let the drill chuck get a better hold of bit but be carfule because this also takes away the drills ability to slip if it hits something solid.
SOURCE: Can't remove the chuck on a drill.
There are one-way (non-reversible) and two-way (reversible) drills. Mine is one-way. Methods for chuck removal are different for these two types.
Procedure for one-way (non-reversible) drills:
Drills of this type have no chuck screw, so one have to hold the spindle with a wrench, than to sharply strike the wrench with a hammer to spin it off.
Procedure for two-way (reversible) drills:
Open the chuck up and in the bottom is a screw that holds the chuck on
the shaft.The screw turns in a clock wise motion to be removed and then
you can top the chuck off the shaft.
SOURCE: When I was done using the hammer drill to drilling
open your chuck as far as it will go look down inside the chuck and you should see where it has come from ,if that is where it came from it will be right hand thread probably allen key or very small socket
SOURCE: New bosch psb 550 re with hammer action. Hammer

I had same issue, So I down loaded Milwaukee,Canadian tools,Amstar Corp.,Service Parts List Bulletin No.54-24-3023 Catalog No. 5351-6 for 3/4 Rotary Hammer with starting Serial No.488-27500 (Part No.48-86-0050 Drift pin) I found one in tool box the Rotary Hammer came in, I had know idea what it was used for though. So I unscrewed dust cap and removed it, I inserted the drift pin into slot under bit base (I used it with the slanted side up against bit base) then tapped it inward with a peen hammer a few taps the bit was loose enough to lift out. One would think that it would be easy to remove the bit when you loosened the dust cap, then it is designed to exert brute force downward on the bit into a rock hard surface pretty much jamming the bit into the chuck spindle. Not a convenient way to change bits but beats the living heck out of drilling into concrete any other way. If you don't have a drift pin to tap in, You can order one or a flat piece of quality steel like a thin chisel or quality flat head screwdriver would probably do in a pinch. Hope it works for you.
