Differences between these two drill chucks?

[drummerdimitri]

I've ordered an extra all metal drill chuck for my Fein cordless drill as I had thought it would come with a plastic bodied chuck as seen in many pictures on the internet but upon receiving it today, I was surprised to see that it actually comes standard with a metal chuck so now I'm left wondering if I have bought the other one for no reason.

This is the one that came with my drill driver:

And this is the one I ordered thinking the above was plastic:

It is not clear what the difference is between the two as on paper, they seem to have identical specs but since I'm not a drill chuck expert, I hope someone here can find specific use case scenario(s) that would make the supplementary one useful.

If they are not differentiated enough, I will try to ask for a refund or store credit as it did cost me a pretty penny.

Looks like the 2nd chuck (64203006010) has some sort of "automatic retensioning"? I'm not exactly sure what that means or how it works, but I assume it means that bits are less likely to slip in it. It also looks physically larger than the other chuck.

The 1st chuck (63208005010) is a very tried and true Rohm chuck that many professional brands use. My Metabo drills use the same exact Rohm chuck, and I think they're fantastic. They ratchet and lock down on drill bits very tightly, I've never had a problem with anything slipping.

Having multiple chucks is a big reason to have any quick change chuck drill. If you only have one chuck, you're kind of wasting the advantage of being able to change the chucks out.

I have 10+ chucks for my drills, and I load them up with all the bits I need for a task so that while I'm actually working I almost never have to take a bit in or out of my drill chuck. One time I was doing a project with a whole bunch of 1/8" rivets, and I loaded up 2 different chucks with 1/8" drill bits. I would change the chuck out every 3 or 4 holes to keep the bit from overheating.

Yes I read about that automatic retensioning however, I have no clue what it means and there is no user manual or datasheet that explains that so not sure if I will ever figure it out. Might need to get back to my dealer and have him contact Fein directly to get more info about this.

It doesn't ratchet like the stock one and has triangular jaws that make a "point" contact with a drill.

Not sure if either has an advantage with drills that have 3 facets at the bottom vs the conventional round ones.

As you have mentioned, it is never a bad idea to have multiple chucks that are easy to fit in/remove as it makes life easier instead of having to change out the drill every time one needs to make a different diameter hole so I will most probably be keeping it but I am really curious to know what benefits, if any does it have over the stock chuck.

The second chuck is a Rohm/Roehm Supra type chuck.
These are mostly machined steel, maybe with a couple parts made from plastic and/or formed sheet metal.
The first chuck is either a Metabo Futuro Plus, or a Rohm Extra keyless chuck. These are a mixture of machined steel, formed sheet steel, and plastic parts.
They tend to be lighter in weight, and also usually have lower guaranteed concentricity.
I’ve read that the lighter weight chucks might both be made by the same manufacturer, maybe Metabo.
Some of these chucks might be made for hammer drilling and dome not, but I’m not sure which chuck type is used in each, since the lighter chuck design comes in designs for both impact and non impact use.
The lighter weight chick does appear to have carbide jaw inserts, which the Heavier Rohm Supra chuck will not have.

I think the Rohm Supra chuck is also likely safe for hammer drilling.

I'm pretty sure Rohm chucks are made by Rohm chuck company.

I'm pretty sure Rohm chucks are made by Rohm chuck company.

The lighter weight Rohm and Metabo chucks look almost identical except for the stamp, and I think Monte or someone ina past thread mentioned something about one of the chuck lines being manufactured by the other company.
Rohm offers a wider range of sizes, which leans towards Rohm, but Metabo only seems to sell their heavier Futuro Top chucks to Hilti occasionally, so other than their own drills, they may have extra cspacity if they actually manufacture the lighter chucks.

The first chuck has carbide jaws.
