I cannot release the drill bit installed. What or how I remove or exchange bits
The black thing at the end is the "keyless chuck". Grasp it just behind the silvery tip of the chuck with one hand, and grasp the knurled ring just behind THAT area with the other hand. Twist the "front" hand counterclockwise while you twise the "rear" hand clockwise. That will loosen the chuck so you can change bits.

Hi,
the Chuck should be 2 Part.
Use 2 pair of stillsons Or pipe wrenches, Tight On the 2 Chuck Parts, Crack in opposite Directions.
Alternative, Use Wrench On Chuck Jaw, Short sharp Blow With Hammer.

To remove the chuck on your drill follow the instructions for the type of drill chuck you have:
Instructions for removing a keyed chuck
Most reversing drills have a left hand threaded screw located inside the bottom of the chuck.
1.) If the unit has this screw place the chuck key, with the chuck facing toward you, into one of the holes on the right side of the chuck. Strike the key in a clockwise direction with a wooden mallet or similar object. This will loosen the screw inside the chuck.
2.) Open chuck jaws fully. Insert screwdriver into the bottom of the chuck to engage screw head. Remove screw by turning clockwise this is a left-hand screw.
3.) With the chuck facing toward you place the key into one of the holes on the left side of the chuck. Using a wooden mallet or similar object, strike the key sharply in a counter-clockwise direction. This will loosen the chuck so that it may be unscrewed by hand.
There is no way to stop the motor from turning.
It may require several attempts to loosen the chuck

2.) Insert the short end of a 1/4" or larger hex Allen wrench into the chuck and tighten. Facing the tool strike the long end of the hex wrench sharply counter clockwise as it is a standard right hand thread. This will loosen the chuck so that it may be unscrewed by hand.

lock the drill in a vise so you can work on it. Then try working a very small screw driver tip into the jaws as you at the same time back up the jaws. They may be jamed against each other.

Hold the chuck by its sleeve, put the drill in reverse (make sure it's set at high torque if you used it in a drill/driver) and go full speed. That should release the bit.

That tool comes standard with a keyless chuck so all you should have to do is grip the collar and turn it to loosen bit. If it is stuck you might try a rag of some sort on the collar and use the motor to loosen it up. Let me know if you need more help.
