Keyless chuck drill??

I've always used my trusty drill with a keyed chuck, and it worked fine til I modded the battery....

But anyways, the keyless chuck on my new drill always causes drill bits to slip... how do I properly use one???

I never trusted those. Always had a regular keyed chuck
 
Turn it to the highest torque setting, insert bit, grip chuck, pull trigger .......shouldn't slip and I'm pretty sure you are already doing this.

 
Damn, I always use a keyless at school when working on sets and crap for the plays. Easiest way is to hold the chuck with one hand and pull the trigger with the other to loosen and tighten. Then you just have to get used to how hard you hold it in place so it gets tight enough, but doesn't start killing you hand. Never had a problem doing it that way, and it's insanely fast.
 
i've got a cheap B&D 18V thats keyless. usually i just grip the chuck as tight as i can and pull the trigger. larger drill bits i'll use two hands and twist. but on big bits that take up the hole chuck i have to use a couple pairs of water pump pliers as keys.
 
RTFM!

If your chuck is not biting the bit, then you need to tighten it by hand, which is a counter twist of the chuch itself. Again, read the manual, you will know how to do this. If this doesn't work, you could have a defective chuck, or bits that have already been "grooved" by a bad chuck on another drill, and if that's the case, those bits may never work in your present drill, unless you insert them at a different point in the chuck. Also, you might want to degrease the jaws of the chuck to prevent slippage.

The final thing I can think of, is just maybe you lack the strength to properly tighten the chuck by hand. 😉
 
I DID RTFM!!!
It's a cheap discount model that doesn't have any decent instructions lol
And no, I don't have weak hands 😉
 
Ive been working with my drill a lot lately.

I grab the top like im about to choke something, and then grab a little lower and make a twisting motion like im wringing someones neck... that usually gets it tight enough it doesnt slip, if it does, try again harder.


could just be a suckyass drill

That may be your problem, as I have never had any problems with "slippage" with keyless chucks before, maybe the chuck is just to cheaply made to grip it properly? How are you inserting it?

or you can just get the bits that have hex ends on them, they cost more but would eliminate any chance of slipping.

Yeah.......and end up stripping something in the motor if the bit gets held up. There's a reason drilling bits are 99% round.

FWIW, Dewalt and Panasonic use a keyless chuck that you can tighten with one hand without pulling the trigger. Very sweet. Each tiny bit you tighten the chuck, it locks.

I'm afraid to use drill bits with the hex shafts.
 
Hex shafts are great. Don't have to worry about the chuck getting jsut a tiny bit lookse and then the bit not gripping.

But to answer the OP, either grab the chuck and pull the trigger. Or turn it with two hands until it's tight.

with a round bit, if you run into something that you can't drill through, it'll slip in the chuck... with a hex bit, it'll do one of two things... because it has a better grip it'll either stop it from slipping and strip out your gearing, or much worse IMO it'll make your drill wrench your arm unexpectedly... this is worse to me because if I'm on a ladder doing something, I don't like being pulled unexpectedly... just an idea

**edit**

those hex bits are really designed to be used in speed bit systems...basically, you have a round bit that goes into your chuck, and then the end of that bit has a hex opening in it that you pop the bits into... best of both worlds

Really? I've never seen a speed bit holder with a round end that goes into the chuck; always seem to be hex as well.
 
you could buy an after market keyless chuck made by Jabocs which will be stronger than then one that came with your cheap drill
however it will cost 1/2 as much as the drill

Isn't that what the adjustable clutch is used for - controlled slippage?
 
Just to be certain... you aren't attempting to drill in the wrong direction, are you?


Oh... the questions you learn to ask when you have housemates that aren't quite the handymen.
