JT#6 chuck: drill questions

[ron in sc]

What chuck, JT#6 would be up there in quality with a jacobs?

I saw a "high performance drill chuck" in grizzly catalogs hundreds less. the jacobs seem astonishing.

suggestions?

Don't laugh at me, but I didn't even know they made a JT larger than 5, what size stuff are you working with?

You might be thinking MT5. There's generally JT3, 33 and 6, at least readily available.

Anyway OP Albrecht is my favorite. But any of the "premium" or heavy-duty imports are probably good enough. There used to be Golden Goose import chucks (which had a picture of a duck or something on the box) that guys quickly figured out were excellent Asian copies, but then one day they were simply NLA

I dunno if he's still around but don't buy anything from 800Watt on eBay.

I should add import chucks are just like import machine tools: probably work well for awhile but parts will be non-existent if needed. Albrecht chucks OTOH are completely rebuildable and VERY easy to service, with every single part available (although not cheap). I believe the same is true for higher-end Jacobs chucks.

Nope, I just always assumed that I had the biggest chuck jacobs offered, how silly of me. Now I have to find a larger one.

A #5 is much bigger than a #6.

As others have already told you Albrecht chucks come from Germany and they are well made.

Great, I still have the bigger chuck, I win!

Rohm spiro chucks are quite good as well. Also German and rebuildable.

If OP is looking keyless the best way to screw these up is to use a big hole saw. They self-tighten and the leverage from a larger hole saw will cause them to lock down much too much; I actually spread the shell of an Albrecht doing this.

Since then I turned a Milwaukee 7/16" hex arbor down to 3/8" (+/- .001") and use in a collet. The other solution is a keyed chuck.

I like that idea, now if I just had a working lathe and mill, notice I said working.

Look at LFA, as well, made in France I believe.

Ron, I have a Jacobs 20N 1" drill chuck on a 3MT arbor I would sell reasonable if that would work for you.

 

[pstemari]

Never mind. Already mentioned.

Good job! I forgot about Rohm chucks also top quality.
