My Rigid 18 V Lithium-Ion drill has a locked up chuck. No matter what I try, I can not unlocked the chuck and removed the drill bit. Have put machine oil in the chuck, let it sit overnight, still can not unlock it. Any suggestion? Ben

don't think there is much to it. See page 4 in this manual

Pull the chuck out to unlock it and push the drill bit and chut back in to lock it.
Hope this helps.

The drill uses a cordless chuck (part bits go into) you will need to hold the outside ring of the chuck and spin it to loosen the jaws on the bit. Then spin the chuck the opposite way to tighten

Try holding the bit with pliers and running in reverse, maybe with a shot of oil. That might free it up. You can also try tapping it (firmly) on the side of the bit

TAKE THE OUTER CHUCK PEICES OFF THE IMPACT!! THERE WILL BE A C-CLIP, WASHER, SPRING AND ONE OR TWO BALL BEARINGS AND THE OUTER HOUSING, IN THAT ORDER! WITH ALL OF THAT OFF, MOUNT THE ANVIL IN A BENCH VISE WITH BRASS JAWS OR BETWEEN TWO PEICES OF WOOD, UPSIDE DOWN!!!!!!!!!!!!!!! THE TRICK IS TO HAVE THE BIT FALL OUT OF THE CHUCK ONCE IT IS LOOSE!!!! NOW WITH IT MOUNTED IN THE VICE AND PRETTY TIGHT, TURN THE TOOL ON UNTILL IT FALLS OUT, IT WORKS GREAT IF HAVE DONE IT ABOUT 75 TIMES!! MOST PEOPLE THINK I'M A WIZARD!! BUT IT'S REALLY EASY. WITH IT MOUNTED SOLID IN THE VISE THE ANVIL HITS SO FAST AND HARD IT VIBRATES THE ANVIL, IF YOU DO NOT REMOVE THE BALL BEARINGS HOLDING THE BIT, YOU WILL BE DOING THIS ALL DAY. SOMETIMES, IN THE CHEAPER BITS IT WILL ROTATE AND GALL UP SO BAD THAT IT WILL NEVER COME OUT, IN THAT CASE YOUR BUYING A NEW ANVIL ASSY. JIMS TOOL SERVICE

Hi,
Soak it with WD-40 and let it set so the lub runs down into the chuck and then try...

heatman101

The chuck is probably attached to the shaft with a left hand thread. Engage the spindle lock and turn the chuck clockwise to unscrew it.

Other than two quick squirts of WD40 and nice new chuck key?

grasp the chuck and put drill in reverse position and pull trigger gently this will open chuck and re-insert bit do same in forward to tighten bit into chuck

according to my breakdown its a drill. do you checked if there is a screw inside the chuck. if there is one remove it by turning clockwise.open the chuck fully & insert allen key 5/16 or 3/8 short side to the chuck.tighten the chuck & wak the allen key with a hammer counter clockwise. do it again if required.putting back together the other way.
