I made a new chuck for my Milwaukee Installation Drill

[@ToolShow]

Well that was freak'n genius. Thanks for sharing James!

[@james.a]

Thanks! Working on more stuff like this 👍

[@steelbak-customs]

This is amazing. Open source and sharing is the way of the future. If it is open source and/ or shared with everyone, anyone can improve on it and we all benefit. Thank you! I look forward to more of this kind of content.

[@james.a]

Open source is the way 🙌

[@greglavardera9178]

What you’ve done is a make an adapter that goes from Milwaukee’s mount to Festool mount. If you changed the printed cone to expose the Festool mount you could mount any of the Festool chucks, which is not so useful, but the mount is shared with Metabo, Hilti, DeWalt, and Fein’s multi chuck drills. So you could mount any of them - for instance the Hilti drill chuck has 1/2” capacity.

[@james.a]

Interesting. Is the Hilti chuck available to buy on its own?

[@NeilDunlop]

That's an amazing piece of work, James! And kudos to you for sharing your hard work. I never even knew you could print metal until I saw this 🤠 FWIW, a Wera "Rapidaptor" will take and hold a Centrotec bit along with normal hex bits. But I'd imagine your chuck will do that with less play so hat's off to you!

[@james.a]

Thanks! Yeah the barrier to entry is generally pretty steep for 3D printing metal but it’s cool that places like Shapeways make it accessible to people who don’t have access to the tech yet in a consumer product. It’s not cheap but it’s possible and I’m sure it will get cheaper over time.

[@adrianbrewer1708]

Hi there James. Nice job. If you make them I will be happy to buy one. Keep up the good work

[@james.a]

Will keep that in mind. If I can reduce the cost it might be worth selling them to anyone interested. Thanks for the kind words!

[@chrislosada6701]

my dude, I'm getting this drill just because of this attachment.

[@james.a]

Nice! I added more links in the description. Uploaded all 3 parts to Shapeways for anyone who doesn’t have their own printer and wants to order the parts. Also shared all the models on Printables for those who want to download them and make their own that way. Included an Amazon affiliate link for anyone interested in buying the drill. It really is great drill.

AWESOME!!!

[@Jtx_Tools]

Amazing bro I wonder does that Milwaukee 1/4 Bit chuck fit on the Festool drills?

[@Jtx_Tools]

This is brilliant! I do have a question Did you not want to modify the centrotec chuck to fit the Milwaukee?

[@nominalvelocity]

Pretty cool! I don't use any Festool stuff or centrotec bits, but with this it's definitely more appealing!

[@james.a]

Centrotec really do have the best fit of any bits I’ve ever used. No wiggling at all once they’re in the bit holder. Maximum benefit when using with a Festool drill but you still get benefit on the Milwaukee compared to other bits.

[@reggiecoupe]

[@CygnusRising]

Do you need specifically the Hex head, or can you use any head for the donor parts?

[@james.a]

You need the hex head. They all have slightly different parts.

[@aaronlambert5815]

James, i thought you said you printed a certain piece in metal, sorry for my ignorance in just now starting to print 3d, but how do you print in metal. Or do you need a different machine for that?

[@aaronlambert5815]

By the way loved the video, thank you very much.

[@james.a]

Yeah. 2 parts I printed myself in plastic. 1 part I uploaded to Shapeways for them to print it in stainless steel for me. Costs about $40 for the metal part which is pretty reasonable considering metal 3D printers are pricey and not really available for households yet.

[@matthewroberts7942]

Do you know what size the ball bearings are? I dont want to tear apart the main portion of the adapter. Looks like i need a snap ring remover which i dont have

[@james.a]

Just took it apart to check and my calipers are showing 3.94mm diameter for the ball bearings.

[@mccrich8094]

James, great job. Very clever. Just curious as to why you did not also print the black Milwaukee back plate parts(?).

[@james.a]

I knew I was going to need some of the parts from the Milwaukee attachment so I just made the parts I needed to make it work. I might go back and model more of the plastic parts but I would still need to source other hardware like the metal ball bearings and the spring. Also the back plate that meets the drill is metal so I would possible have to print that in metal too because it keeps the whole thing from spinning I don’t know if plastic would hold up. Thanks for watching and commenting!

[@kobie4238]

Cool

[@wingsdesire1]

Hey James & every one have you managed to find a drill driver bit (e.g. Phillips) that fits centrotec that is not Festool?

[@james.a]

SnappyTools has some Centrotec compatible bits: www.snappytools.com/product-category/festool-centrotec-compatible-accessories

[@wingsdesire1]

@@james.a thank you James ☺️

[@AlexK07010]

Nicely done. do you have a link to the bearings? also what orientation did you print the 3d printed parts?

[@james.a]

I purchased an additional 1/4" Hex Bit Attachment on eBay so I could disassemble it and use some of its parts for my Centrotec Adapter. Includes the bearing portion. Washer I printed flat. Housing printed short side down. And the metal part was printed by Shapeways so I’m not sure of that orientation they chose.

[@AlexK07010]

@@james.athank you. My metal part just arrived

[@AlexK07010]

What material did you print the 3D parts in? Pla or petg? Did you use supports for printing? Finally got all the parts and ready to assemble

[@james.a]

I used PETG since it’s more flexible and less likely to crack. I can’t remember right now if I used supports though.

[@AlexK07010]

@@james.a thank you. Printed them out. How much filing and sanding did you have to go do the metal print? I’ve been at it for over an hour already and still not fitting

[@james.a]

@AlexK07010 I can’t remember how long but you’ll want to keep checking the size often so it doesn’t get too loose. And make sure to do each side evenly so it stays centered.

[@AlexK07010]

@@james.a yep that’s what I’m doing. Outside ones need sanding as well to fit the centrotec

[@james.a]

For the centrotec part to fit I attached the metal printed part to my drill so I could spin it fast while holding sand paper wrapped around the tip to sand it a bit quicker.

[@PhilippFedorov]

hi, great work, can i order one copy from you?

[@james.a]

Thanks! I shared the 3d models if you’d like to make one. I think the cost would be too high for the amount of time it would take me to make them for sale.

[@james.a]

​The breakdown of materials was around $35 for a used Milwaukee attachment that I could take apart to use some of the parts, another $41 to print the main 3D printed part in stainless steel, and then I just printed the other 2 smaller parts in plastic myself for probably about $1. So that's about $77 in material costs not to mention the time I spent putting it all together. So how much do you think I should charge to make it worth my time getting all the parts and assembling them? In my honest opinion I think I 'd have to charge more than people would be willing to pay so I shared the design so anyone who wants to can make one of their own can. Sorry for the rant. Hope this answers your question!

[@mackwoodcock7484]

I’ll buy 1

[@james.a]

I guess the question is: What would be a reasonable price?

[@mackwoodcock7484]

@@james.a $50 USD?

[@james.a]

@@mackwoodcock7484 The stainless steel 3D printed part alone costs $40 from Shapeways unfortunately. If I can recreate the rest of the parts I borrowed from the disassembled Milwaukee hex attachment then printing those in plastic would be relatively cheap. Then I’d need to source the 3 tiny bearings and a spring. 🤔

[@gf2e]

Good luck! Most people have no idea how much engineering goes into making mass produced parts be cheap. I kinda want one for my Bosch installation driver, but I don’t have any Centrotec bits. I’m just annoyed at wobbling hex bits :)

[@duckels1]

@@james.a theres probably a decent enough market for this that you could do a bulk order from shapeways to bring the cost down, have you tried any other materials to see if they'll hold up?

[@duckels1]

awesome stuff, really genius design James is the washer not already part of the piece it goes into because its a consumable? just curious what the reasoning behind it was

[@james.a]

A few reasons: The washer is separate so it prints better without needing too many supports. Also I was adjusting the size of the middle hole many times for the right fit. And finally, I thought that part kind of rubs a lot when the metal part is spinning a might need replacing over time but I need to use it more to see how it wears.

[@MrPatateHead]

Awesome mod! Can someone explain to me the advantage of Centrotec? After watching a video about it, the only thing I see is a clone of the classic 1/4" quick change bit holder but incompatible with 1/4" just so they can sell their own version of every bit/drill/etc. Am I missing something?

[@james.a]

They're basically just way more precise than most other bits. The tolerance they make these at means they cost more but I've never had to repurchase any Centrotec bits so far. You lose a little of the precision when pairing it with a Milwaukee drill instead of a Festool drill but they still wobble much less compared to using a Milwaukee with regular bits. The metal 3D printed part is a very snug fit so you have to lightly file it down to fit just right. This is by design so when you are trying to drill with a long bit it doesn't wobble back forth from being a loose fit.

[@MrPatateHead]

@@james.a thanks for the clarification!

[@mrniusi11]

@@james.a precision? in what way? snugness to fastners?

[@james.a]

Snugness to fasteners is better and less wobbling of the shaft when spinning.
