- Ever wonder how the SDS chuck works? How does it hold the bit while still letting it move? And what are those slots for?
Let's take a look!

That means more drills, more of the time :)

My knowledge of chucks and ballbearings increased by watching this video. Thank you for the lesson!
The best demonstration of how it works!
Thanks
Interesting explanation. easy, understandable and helpful .. thanks
Informative and well organized. Thank you, sir!
Allah razı olsun dayıcım :)
My old Dewalt SDS chuck is smooth bore with no keys, so the ball bearing takes all the rotational forces. It has no circlip, either.
Perfect.
nice nice nice, keep up the good fight !
Thanks mate! Just doing things I found interesting
how does the bit moving back and forth get joules against what is being driving down or chiseled? I got a post driving bit - but if the bit slides back every time it drives forward - just sliding back and forth pneumatically? I don't see how that creates force besides just pure rpm. How can it push against anything if it just slides back against itself every time?
It doesn't slide when it is pressed against the material. the hammer strikes it when it's pressing and the bit doesn't really move. like if you're chiseling something by hand, you put the chisel on the material and hit it
@@BoltahDownunder Nice! The hammer hits it when it's pressed against the material - makes sense now!!!
Yep. And some drills will only hammer when it's pressing!
@@BoltahDownunder good to know - I'm gonna use this rotary hammer for my shiitake log inoculation. I've been using a 1200 rpm drill and the Bauer rotary hammer says up to 4500. Should save me a lot of time. I need to order that bit though. hahaha.
My dad managed to F up the chuck to my hammer drill - which he, I quote: "needs a new ball bearing" - So is it done with a new chuck - or can it be fixed with a new chuck fixing to the SDS ?
You might just need a new ball or a whole new chuck, I can't say. You'll have to disassemble it and see. It's likely just one of the smaller parts like ball or rings so that should be simple enough to replace, but if the metal tube that holds the drill bit (the tool holder) needs replacing that's a bigger task that requires opening up the whole drill.
Best check with the manufacturer or Google you model number + parts, or chuck replacement to find out
Thank you sir my problem is solve
