I newly bought a Bosch PSB 500 RE strength drill and already I kinda screwed increase the machine.

You are watching: How to take out a drill bit

The chuck is keyless, consists of two components which I"ll describe as the head and the base. Girlfriend would host the base and also rotate the head loved one to the base to ease or tighten the bit.

The device is also equipped with a grip the is situated on the drill body just prior to the base of the chuck.

While drilling this grip slipped and caught the base, quit it from turning, for this reason that only the head the the chuck was transforming in the fixed direction.

Now the totality chuck is as well tight and it appears I can"t release the bit any type of more. Any kind of solutions?

Edit 1

I tried wearing gloves, that didn"t help. I likewise tried putting some WD40, yet that didn"t help because the little bit is way too tight.

I heard the the chuck assembly have the right to be replaced, what perform you think?

Put the drill in reverse, steady grip the lining (the part you were calling the head) and gently to express the cause up the point that friend cannot organize on. If you hear clicking, and also it doesn"t torque really much, you should turn the torque setting up come the maximum (the highest number, or the drill setting if it has one). If it still doesn"t budge and also you"re no able to organize the chuck against the force of the drill, you may want to usage something more powerful than your hand to hold the chuck. A strap wrench is fine designed because that this task and also won"t damages the chuck.

That happens as soon as in a while with such chucks. Been there, loosened that. Don"t worry.

When every else falls short I plunder the chuck ring in cloth and use a pipeline wrench. Sometimes only much more torque deserve to help. Simply be sure you"re transforming it in the appropriate direction.

I tried all the suggestions I could find top top the web that worked for others, however none functioned for me together my drill little bit was way much more stuck than theirs ns guess!

The proposal (and the result, for this reason you are warned what might go not correct if you shot it!):

hold the chuck and run the drill in reverse - I virtually burned my hand. Make the efforts it through a thick gardening glove on, and still almost burned mine hand.soak the head in WD40 to loosen the bit - nothing obtained from this because that mehit the drill little into the chuck as this helps release the jaws inwards - regardless of multiple bashes through a hammer nothing budged and the drill bit was no more loosened than once I an initial starteduse a strap wrench - the only means to perform this was to grip around the chuck and also run the drill in the contrary direction. As the drill bit was so stuck and the drill torque to be so high it to be the drill (rather than the chuck) that started to rotate and started relocating towards drilling into my arm!

In the finish I supplied two strap wrenches, one at the allude the chuck have to be turned and also one simply below. With the drill battery disconnected i was nearly standing on the lining to put sufficient force right into the strap wrenches. There to be so much force the lining distorted into an oval (and this to be a high quality drill), yet eventually the popped and also the drill bit came free.

Incidentally ns oiled the chuck afterwards as it was very stubborn (despite the previous oiling) i beg your pardon was most likely a contributing aspect to exactly how stuck the drill little was.
