How do you get the chuck off - Electrical Supplies

To remove the chuck from a Wilmar KFF-6 drill, follow these steps:

1. Turn off and unplug the drill.
2. Locate the chuck key that came with the drill.
3. Insert the key into the chuck and turn it counterclockwise to loosen the jaws of the chuck.
4. Remove the chuck key from the chuck.
5. Grasp the chuck with one hand and hold the handle of the drill with the other hand.
6. Turn the chuck counterclockwise to remove it from the spindle.

If the chuck is stuck and won't loosen, you may need to apply some penetrating oil to the threads and let it sit for a few minutes before attempting to remove the chuck again. You can also try using a rubber mallet to gently tap the chuck counterclockwise to loosen it.

If it is a reversible drill there is almost certainly a left-handed thread screw or allen bolt through the centre of the chuck into the drill shaft and this must be removed before the chuck can be removed.

If it is a keyed chuck select low gear if there is one, fit the chuck key and then strike it sharply with a hammer to jar the chuck in an anti-clockwise direction. Usually it takes only a couple of blows before the chuck is loosened.

Keyless chucks are more problematic. I hold them in a vice and use the drill in reverse which has proved fairly successful, though sometimes the chuck is only fit for scrap afterwards.

Lots of the keyed chucks can be taken apart for cleaning and lubricating if necessary.

Hello,

With the chuck open as far as possible, look within the jaws of the chuck for a bolt or screw head that attaches the chuck to the shaft. Remove the bolt/screw and remove the chuck. Some chucks can also be screwed onto the shaft, so look for signs of threads at the base of the chuck. Otherwise, once the bolt/screw is removed, tap along the outside around the chuck with a plastic hammer to loosen the chuck. Penetrating oil will help.
Take your chuck with you to a "big box" type hardware store, where a replacement should be available. Any well stocked hardware store should be able to help you. I have found that the somewhat smaller hardware stores are usually staffed with knowledgeable persons, and getting a replacement ordered is easier. One is more likely to be stocked in the larger stores.
The name brand of the chuck isn't as important for a replacement as is the correct shaft size and style of fit.
Best regards, --W/D--

Open the chuck wide open. In the center is a retaining screw, they usually have left hand threads. Remove the screw. Take an allen wrench1/4" to 3/8" in size and fasten the short side tightly in the chuck. The chucks are usually right hand thread, so take a small hammer and strike the allen wrench to turn the chuck to the left to loosen it. Once you have the chuck off, verify the thread size of the drill motor shaft, then go to McMaster-Carr and choose the one you need.

If your Makita matches the one on the picture, you will need a chuck key to attach a drill bit or tool to the machine's chuck. The chuck key inserts to any of the small holes in the front part of the chuck and at the same time its teeth interlocks with the teeth of the chuck. When turning the chuck key you will widen or loosen the grip of the three jaw pieces, that clamps to your tool or bit. Tighten the chuck key by hand until the chuck grips the bit securely. For safety, unplug the power cord whenever operating the chuck key on the chuck.

hi friend,
Step 1. Determine what kind of replacement drill chuck you want - a keyed chuck or key less chuck. Over the years, key less chucks have been widely used for handheld power tool drills, due to their improving grip torque and convenience.

Step 2. If you prefer replacement key less chucks, then you have to know what type of key less chuck you will need - a single sleeve key less chuck or a double-sleeve chuck. You can simply determine it by checking your current chuck. If your current chuck is a keyed chuck or a double sleeve chuck, then you will need a replacement double-sleeve key less chuck. On the other hand, if your current chuck is a single sleeve chuck, then you should get a replacement single sleeve chuck.



Step 3. Confirm the threaded mount size (spindle size) on the chuck. 3/8"-24 threaded mount for 3/8" capacity drill chucks and 1/2"-20 threaded mount for 1/2" capacity drill chucks, but there are some exceptions where just the opposite may occur. To be safe, always check the threaded mount before you buy replacement drill chucks.

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
Instructions for removing a keyless chuck

1.) If the unit has this screw 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.
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.
