DEWALT Drill Chuck for Impact Driver, Quick Connect (DW0521)

Perfect fit for my impact. So far so good on toughness ,little to no wobble and keeps me from having to switch to my drill when I definitely prefer my impact more.

When you try to buy drillbits for your Dewalt power driver, they should tell you you have to have this chalk to use the sets of drillbits

Strong grip, quick change

Great quick change chuck

I have purchased three of these for various uses and all of them break within a few uses. The chuck is threaded and then glued onto the post that inserts into the drill. After a few uses the glue or adhesive that holds the chuck together gives way and the chuck separates from the post. Because of this, the chuck can no longer be loosened and the bit is stuck. Not only can you no longer use the chuck but you lose the bit as well. I love my dewalt drill but this chuck is very poor quality.

Dewalt. That says it all.You get what you pay for.I like it. Exactly as described.

Exactly what I need

Gonna keep this short - three serious issues to mention:1. Because of the torque threshold of an impact driver, you cannot tighten your drill-bits beyond that threshold. Unless you can manage to find a way to do it manually, which I have not. Maybe my fingers are too large to get a grip on both parts of the chuck? I believe you may be able to use a hex-key to secure the bit, but I'm a big fan of quick connectors and fast-bit swapping, and do not like carrying around 10 different keys for 10 different tools.2. My Dewalt impact driver engages a fast-break action when you release the trigger, stopping the drill-spin almost instantly. I'm not sure how unique this feature is between other brands/models, but will assume most impact drivers employ it. When the auto-break engages, the reverse-angle velocity of the break loosens the chuck's grip on the bit. So every 1 to 5 spins of the drill, your bit will fall out of the chuck, likely into some tiny hole of the device you're building, never to be seen again.3. The shaft (the part the drill holds onto) will come unthreaded from the chuck (the part that grips the bit), and will never work correctly again until you super-glue it back in. However, this issue was very easily fixed with super-glue for me, and has not caused nearly as much grief as problems 1+2.The only method I've found to get around problem #2 (mostly caused by problem #1), apart from using a hex-key (if that is possible) is to manually release the trigger gradually, to avoid engaging the auto-break. This sounds like a simple thing to do, but it is not. The break engages very easily, so you have to release the trigger very gradually in order to avoid it.Finally, a tip to the manufacturer: Please redesign this chuck to better allow manual tightening of bits with your hands. Or redesign it to allow tightening bits without turning the chuck at all, if that is possible.
