Milwaukee M12 cordless drill chuck runout

[90zcar]

I said something about this under another thread but I recently got a Milwaukee m12 combo kit and the drill I noticed the plastic sleeve grip for the chuck is somewhat wobbly when spinning. I stuck a drill bit in it and the bit doesn't seem to wobble like the plastic sleeve does. I'd say it remains somewhat true when spinning. I just want to know how straight these chicks are supposed to be on this and is it worth returning to try to get a better one. I actually found a video on YouTube that is identical to mine and basically doing the exact same thing.

Like I said this is not my video but it's doing exactly the same thing

The kit I purchased recently had the same drill with the same problem. I returned the kit to Home Depot and exchanged it for another one. The drill in that kit was fine. Great little drills.

So there are other ones out there then that don't do that. Well then it looks like I'll be returning it then..

Maybe I'm just being picky and this is how it is for a $100 drill. When I stare at a bit spinning in it...it is pretty true for the most part. That wobbly plastic grip is what's bothering me I guess. Just hate to run out and try and return it only to find out they are all like that and I was just over thinking it

What matters is if the bit is staying true. If your going to return it go for the fuel model with a metal chuck.

The fuel models are well worth the xtra$$$$ with the drill and impact driver

This one has a metal chuck, not sure why I said plastic. The fuel drill alone costs more money than this combo kit

Are you seeing the textured grip wobble and not the chuck? Sometimes they are not cut perfectly square and thus giving the allusion of a wobble.

The black grip definetly wobbles. The silver metal ring at the end of the black grip also wobbles. When I make the 3 finger chuck small and extend it out to where I can see it I can't quite tell if it wobbles.
A senior simple 3/16 or small drill bit I can't tell if that wobbles either but a large spade bit definetely wobbles but who's to say those bits are true and straight.

Stick a ground dowel pin in the chuck if you need a reliable straight reference. You can use a dti to measure runout if you can clamp the drill in position.

So I went to Home Depot today and played with about 15 other cordless drills only to find out most all of them have some degree of wobble. Mine tho was pretty bad compared to the rest so I returned it and opened the box at the return desk and said I wanted one that was atleast better than mine. I found a pretty decent one so I exchanged it.

That being said tho I have come to the conclusion that pretty much the chucks now days just **** period

Mines is a bit clunky too but that's to be expected with these things.
If you need something with higher accuracy and quality look for a cord or air hose.
I have a nice IR but it's a nearly $200 piece. I also seldom use the thing
If I need real precision I'll get it under the drill press or use a mag drill.

 

[90zcar]

Exactly. No matter how good your chuck is you aren't going to get high precision with a handheld.
But the chucks on cordless drills years ago were never this bad.

Mine is not too bad it was the first thing I checked. But I heard some people get bad ones out of the box

Works ok I have pushed uni, Forstner, holesaw on it and it still maintained trueness. I thought I would start warping the chuck for sure.

I use it for everything now..

True, but this is what the consumer wants...years ago it cost $300+ for a cordless anything.... back in 99 or so I bought a Makita 12v and it cost me +/- $200, today you can get the M12 Drill, Impact Driver, 2 batts & charger for 99... Love my M12 drill.

-M12 Drill Kit - $99
-Complaining about "runout" on an entry level, hand held drill - Priceless

Cost is not relevant here IMO. With modern manufacturing concentricity should not be a foreign concept.

If you choose to chuck up a dowel pin realize that 10 thou and possibly more is acceptable. I once read where Jacobs won't guarantee better than .006" in a mill, and most basic lathe 3-jaws are happy to hold 6 thou as well.

Oh I'd say it has everything to do with it. Starting with the Design of the chuck. Comparing a Super Chuck to one is an easy example...Super Chuck is pretty much all machined components, ball bearing thrust surface, etc. This Cheap drill chuck has a faction of the machined components, and I'm sure the plastic sleeve is cast/pressed onto the guts after the fact...so its "hard" for them to ensure the sleeve is concentric in relation to the jaws..

Materials & MFG Methods were chosen to meet Financial Constraints.

I've got an offshore Super Chuck knock off which cost a fraction of the cost of a true Jacobs, but runs just as true as my genuine 14N. In this example, I would say yes...cost is not relevant cause the mfg methods were the same...and like you said, using modern MFG methods and tools, concentricity is not an issue.

I spent $150 on the drill and driver. If you don't think that's a lot of money that's fine but it's still $150 out of my pocket and if I'm not thrilled with the runout of the drill I don't that that's a far cry....especially when these milwaukees are hyped up so much. It's not like I bought a $30 harbor freight special.

It took 3 drills tho to find one that I feel is acceptable. There is no consistency at all.
