These are known for the spring in the nose (#12) to fail.
Using an o-ring pick or small screwdriver remove the hog ring on the end of the bit holder (#17).
Slide the washer, spring, and sleeve off (Be careful not to lose the small lock ball)
The spring that pushes the lock ball forward (#12) is usually the culprit.
Reassemble in reverse order DeWALT DCF886D2 20V Impact Driver Parts
Remove the ring clip which holds the chuck outer sleeve in place and take out the washer and spring, the outer sleeve should now slide off, under the sleeve you will find two steel balls in the holes of the driver shaft, remove them (use a magnet if they won't come out easily) you should be able to get the bit out now, if not clamp the bit in a vice and using a soft face hammer strike the end of the driver shaft to release the bit. Note: dismantle the chuck over a cloth in case the balls fall out so you don't loose them
On this particular tool, you can't really tighten the bit in the anvil like a bit in a drill chuck. The bit is free floating but held in place by a small steel ball. The steel ball is held in place by the sleeve that slides up and down to release the ball so the bits can be changed. The sleeve is held down by a spring. Bits falling out can be caused by: Using bits without the groove in the bottom of them for the ball to catch in, dirt in the bottom of the anvil so the bit can't seat properly, the ball is missing or stuck, the spring is broke or binding, or the sleeve is bent or too dirty to slide up and down freely. Use compressed air to clean the anvil well and WD40 to clean and lube it further. If bits still fall out you'll have to take it apart and see if the ball, spring or sleeve need to be replaced.
Chuck is the part that holds the drill ...normally you would tighten and loosen by hand. There are three jaws that actually hold the drill bit. ... You have an impact driver ... if yours is like the tool pictured, you don't have a drill, you have a impact driver which had a 3/8 or 1/2 square drive.
I hope this answers your question ... thanks for your visit today.
Hi, Yes.... the bits can "spin" just a bit and will jam in the chuck sometimes... Grab the bit with a large pliers and spin it backwards with a hard jerking motion... then the bit will release...you can also use the pliers to get a better grip on the bit to pull it out easier when the release is pulled back... But it is just twisted a bit in there and you just need to twist it back again...
VERY GENTLY. . . . use a flat tip screw driver to try to push the collar forward so that it will release the bit. You may need to gently hold the handle of the impacter in a table vice or something like that to steady the tool, then push forward on the collar with a screwdriver and use a pair of pliers to pull outward on the bit at the same time.
Or instead of a screwdriver try vicegrips that are adjusted loose enough to just lock but not squeeze when closed. Pliers that grip too tightly may bend the collar and keep it from being able to slide forward to release bits.
Could be 2 problems, first are you using the right type of bit to lock in this tool and second the ball that locks into the detent of the bit might be stuck or the ring holding it in has moved. Give me a brand and model number and I will find a breakdown for this and see if I can give you more help
My husband explained this, via phone ..... made it simple....... grab the silver ring area beneath the black top area where the drill bit is located. Hold the silver area firmly, while you twist the black top. You will see the release, then remove drill bit. Laymen's terms, but it worked!!
