DCD710 12v max drill - making it right

[helidriver]

Hello all,

This is my first post here but I wanted to share something I did in case it helps other people.

I bought the 12v max drill/driver a year and a half ago shortly after it came out and I couldn't stand the chuck wobble. I took it for warranty twice and by the third chuck I realised the "Jacobs' 4000 series" is junk. Using small drill bits (which is primarily what I use a lightweight drill for) was imprecise because of the wobble in the chuck. I understand of course, cheap drill is going to have a cheap chuck and I suppose its a miracle it has a ratcheting chuck at all really considering its price point.

I've always had great experiences with chucks built by Rohm from germany. Dewalts best drills come with the rohm chucks, and so did an old porter cable cordless drill I had from before they were bought out by black and decker. In fact the chuck that old cordless drill had on it is still the same one on the 20v max premium hammer drill today. I did some research and with much difficulty found out the name of that chuck (Extra RV) and that it comes also in a 3/8 -24 size which is the arbor that is on the 12v max drill. I've used many chucks and this is the best one out there in my opinion. It will never slip or become stuck and too tight unless you don't turn it enough to feel the ratcheting motion...  It doesn't have the carbide teeth at that size but its not a hammer drill I'm not too worried about slippage.

For anyone interested, the ROHM model number is 893351 for the exact chuck that perfectly fits the 12v max drill/driver.

It is far superior to the stock chuck but of course costs a lot more. Almost as much as a bare tool drill itself. It doesn't effect the balance or weight in any noticeable way.

Hope this helps someone.

sorry I guess I posted this in the wrong forum. Moderator could you please move this to how to's

hi, you must have a very steady hand because the "wobble" of the stock 12v max drill does not bother me... in fact, i have not noticed this wobble myself. also, i don't believe this tool is sold bare, i wanted to buy another for home use bare but i googled and nothing came up... the drill/driver alone with batteries is 160 dollars here.... combo kit with the impact is 180. BTW, the stock chuck works for me... i just twist it to really grip bits. so all rohms don't have wobble? and all rohms have hand ratcheting chucks? i guess i don't understand what you are saying... sorry.

[helidriver]

Yea clearly you don't

I didn't say all Rohm chucks are perfect. I couldn't know that. I do believe Rohm makes the highest quality chucks though from my personal experience.

In my opinion the Extra RV is the best cordless drill chuck out there. If you don't notice the wobble in your 12v max then I am happy for you. Either you don't care or maybe you got a really good one. Either way you dont have to spend the extra money that I did. I tried 3 different stock chucks and they all wobbled, and I do care. I bought one Rohm chuck and it was totally true. It also feels more durable being all metal.

When I ran the stock chucks at high speed the vibration was noticeable in the drill. With the Rohm Extra RV there is no vibration at high speed and the tip of the drill bit is perfectly in place without moving around.

Like I said, the premium quality chuck isn't for everyone, not every one cares enough to spend the money and I understand that.

You can buy a brand new bare tool 12v max drill off ebay for ~70 dollars.

I bought the drill impact combo and the chuck wobbled on the drill, returned and exchanged and the replacement still wobbles, but not as bad the first one.  What's disappointing for me is that I paid a premium price for a tool that appears to be built with substandard quality. For what this drill costs, it should not wobble.

[tooljoe]

sorry but you sound like a salesman... provide evidence of this "wobble" and then i can believe you.

[helidriver]

As much as I would love to go to the trouble to change chucks and make a video of it then change back just to show you what I'm talking about, I think I'l pass. Its not my desire to convince people to change their chucks. I am just trying to help people, I really don't care if you disagree with my opinion of the jacobs 4000 series chuck.  The only reason I made this thread is so that if there are others that are bothered by the same thing as I was, they know the right size and model of a more premium chuck that will fit the DCD710 and work well with it.

It is intimidating trying to find the right model and size chuck for a drill when you don't know and even harder yet to find a place that sells it. I can't help you find a place that sells them, but I posted above the right model number you are looking for that fits this drill specifically.

(I actually emailed rohm after I figured out the model number, asking who sold them in Canada. A CEO of all people emailed me back informing me of a supplier who in turn referred me to a retailer that could order it for me!)

my intentions are/where not to be a bad guy, just that of a judge in a court of law... i am just tired of hearing BS from people to be honest....and i am sure you are too. that is why you just do your own thing.

you don't even have to change chucks, just take video of your recent chuck and i can figure out the rest. plus, once i find out for what you are your using your drill/driver, piece of cake to see if you just have ADD or the chuck "wobble" is reall a huge problem... not that i don't like perfection...i do, but don't make it sound like this wobble cripples... i am willing to analyze my jacobs chuck in an out for anything...

see, if you want me to be technical about things, nothing is perfectly balanced... and some jobs require more balance than others... trust me, i have been taking aprt things since age 9 yrs old... so i can tell you that any motor out there is out of balance unless the main priority is to be 100% balanced, and even then, that cannot be achieved... 

sorry, i even googled for jacobs wobble problems to no avail... so that eliminates the "wobble" problem. for the time being at least...but not big enough to cause a panic. so if you don't bother to go through the "trouble" to show your issues, might as well not mention it at all... IMO.

look at this brave soul... see the confusion it can cause?

[helidriver]

I don't feel the need to prove to you what I already know for myself. I have nothing to gain but winning an internet disagreement and as enticing as that is, its not worth me making any videos or uploading them anywhere. You might see yourself as a judge but you are not. You are nothing but another user who happens to have a different opinion than me.

I've used drills all my life. This one had the most wobble of any I've owned. Its also the least amount of money I've payed for a cordless drill. I tried to warranty the problem 3 times with varying degrees of success. I eventually solved the problem on my own. I am providing the information for other people who might happen to have a similar experience.

The end.

take a look at this video i took myself of a dewalt frame less motor commutator...

i guess since it is not BALANCED i should replace it...

see the Milwaukee has the same chuck...so why just make it sound like dewalt makes jacobs chucks...  i am sure other drills use jacobs.... so i guess they are bad...but bad for what? what is your trade guy?

You are awfully defensive,

I only said the jacobs 4000 series has been wobbly for me. I never said or suggested that dewalt was the only user of jacobs chucks, I also never suggested that ALL of the dozens of different styles of chucks that jacobs makes are crappy.

The milwaukee 2410 has an all metal chuck which is different than the one on the dcd710 and I have no opinion on it since I haven't used it.

Not sure what confusion you're talking about.  My drill chuck wobbles.  The noese ring of the chuck does not run true, nor does a bit when it's in the chuck.  For most hand drill applications, this isn't an issue.  After taking on drill back I chose to live with the wobble.  I went with Dewalt after returning two Bosch 12V compact drills that also had chucks that loosened and began to wobble.  I solved my Dewalt problem by buying a Bosh 18V drill which just about the same size as the Dewalt 12V.  Of these new 12V max tools, the drill has really disappointed me.  The screwdriver and impact are great, just wished the drill had been built with quality that Dewalt claims.

all you have to do is prove your wobble, that is all. the rest is just shooting in the dark. i can say i can jump 10 feet high, but with out the proof, i guess i am just talking about it.

i am just trying to understand "your wobble", that is all. what does this wobble really looks like in video or in real life, is what i ask myself.  also, does an all metal chuck has no wobble... of course, based on your logic, all chucks that have plastic do?

[tooljoe]

BTW, i missed this part, how do you know a CEO replied to you?

A CEO of all people emailed me back informing me of a supplier who in turn referred me to a retailer that could order it for me!).

guy, is it that hard to show the "wobble" on video? (reminder, you are posting to help others, so come through! i need help and so do others) help please. explain the wobble with a video at least?

[helidriver]

I don't think it matters what I type in here becuase you either don't read it or understand it anyways. Green tiger slush party turbo escalator mitten mattress. Wild donkey sword fights! lol

As for your search for proof I am going to make this as simple as possible, maybe this time you will understand?

Me install new chuck already.

Too much work to prove wobble.

Me not care if you believe me or not.

Still with me guy?

All kidding aside though guy, I just can't understand your train wreck of a post. You need to re read your messages before you hit the "post" button so we can understand what you are writing. Thanks sport!

Oh and you were wrong about milwaukee drills. Turns out they make their own chucks they don't use a 3rd party like jacobs or rohm. I also never said all metal chucks can't wobble either! You gota stop putting words in my mouth tiger!

I'm reviving old thread here.  After doing very much research I went with the dcd710s2. I disassemble many devices and power screwdrivers work the absolute best of course. 30+ screws etc.

I went with the 3/8 drill instead of 1/4 screwdriver so I could it for household DIY type stuff.  I bought a Dewalt 14.4v many, many years ago. Best drill I've every owned. Year was 2000 to be exact.  Was awesome.  Other guys I worked with were using 18v Dewalt tools. Zero complaints and never even heard of chuck wobble.

I did research and everything pointed to the dcd710s2. Was actually excited when I got it.  Still am to be honest. Been using cheap battery powered screwdrivers that don't last.  I found a used 9.6v Makita while back and its just too heavy for my work and batteries are wasted.

Anyways, I paid $120 shipped for the dcd710s2 shipped which is pretty sweet.  I don't mind paying more for basically just a screwdriver as long as its proper. I believe everyone would agree, right? Having a proper tool that will last and work the way I want is well worth 2x that to me.

The first day I had it I was testing it out.  Zero chuck wobble.  None at all. I was very happy with it.  Second day actually working with it(same 1/4 magnetic bit holder never moved)and its wobbling and vibrating when I use it.  WEAK. No matter what I do.

It still works just fine for what I do but having a 'brand new' tool that has chuck wobble just isn't right to me.  I was searching around and found this post. Haven't seen anything else on the internet talking about which chuck to upgrade this one to.

I am calling in warranty tomorrow but something tells me its a waste of time.  Going to call anyways and see what they say.  

My whole point of this post was to give a huge THANKS to the OP for the valuable info. I'm down to spend some bucks making this thing work the way I think it should.

BTW, if you guys want me to run any test or anything to show you what a day old dcd710s2 chuck wobble looks like I'll show you. Granted, its not bad but Dewalt is supposed to be good.  I still like it though. Much better then what I was using before.

EDIT:If you're wondering why I don't return it, its because I bought it online. This isn't really a seller issue to me and returning it wouldn't be the best thing to do. I'd rather mod it and have it work properly then do that.  Hopefully Dewalt is doing something to correct this issue though.  Maybe they are using proper chucks for the problem ones idk...
