Great for Impact Drills
Got a DeWalt Impact Drill and didn’t want to buy all new drill bits that have the adapter - so bought this chuck, and it works great! Love it. Made in Japan and WAY better quality than I would expect for the price. This is a throwback to the best of the best DeWalt quality!

Good, but not great. Slips often
The instructions say to insert the bit, hold the chuck and then let it ratchet a few times when tightening. I did that, but the drill bit still likes to pop out anyway. Annoying, but not a deal breaker. I love being able to use any drill bit with my battery powered drill.

Must have!
Highly recommend! Fits impact, power “screwdrivers” and other power tools. Gives tools the ability to use any kind of drill bits now! Good for work and home use, super durable. Little on the heavy side but everything else about this product is great. Easy to use and install as well.

A faulty design by a good company. Don’t buy it. It jams too easily and is unusable.
How disappointing that a $50 DeWalt tool fails after a single use. I received the chuck today and used it twice. After removing the drill bit after the second time, the chuck could close to tighten the next drill bit. It is stuck in the open, the largest position, I tried to loosen it with a lubricant, banging on the front and back, and using an awl to pry the three tabs that hold the drill bit, but nothing worked. It is shame that this DeWalt chuck doesn’t need a chuck key. That may give you enough torque to loosen it if it jams like it did.

SOLID - HEAVY - Very well made
SOLID - HEAVY - Very well made and most of all it's truly centered so your bit doesn't wobble - I put mine on an old Type I Craftsman drill that has wrist-breaking power so now I don't have to keep up with a chuck

INFORMATION FOR PEOPLE GETTING BIT STUCK OR UNTHREATENING THE ARBOR.
INFORMATION FOR PEOPLE GETTING BIT STUCK OR UNTHREATENING THE ARBOR. So common sense would dictate this is obviously not a single solid cast or machined peace but rather multiple components assembled together to create a very handy keyless drill chuck that ready locks in to your impact driver. As such the arbor is threaded into the rear of the chuck that being said when used with an impact driver you can over tighten the locking ring of the chuck (black ring) to a point that it's tighter than the threads of the arbor that go into the rear of the chuck. Two simple FIXES! If you do manage to unthread the arbor simply apply a dab of red Loctite or even super glue or nail polish reinstall the arbor securely into the rear of the chuck then let it cure. Now use it as normal and get back to work. In the event that your chuck is still torque to a greater spec than you can manage to loosen with your attached impact driver just add leverage to solve your problem put a pipe wrench or channel locks or bench vise pretty much whatever you have handy on the silver forend and another pipe wrench or vise grips on the black ring turn the wrenchs opposite of each other to loosen the bit and now you're back in business simple fix no need to return it or assume you lost a drill bit to the cuck it's a very simple keyless chuck that plugs into an impact driver not much to it (same goes for the Dewalt or Makita version I use both) . Always remember the 10 percent rule! Ya gotta be 10 percent smarter than the tool your using.

Broke after a few uses, But Dewalt replaced under warranty
***UPDATE*** As a homeowner this initially was a nice accessory for the Dewalt cordless drill (which I do like, and use all the time.) This chuck just broke today. The steel shaft that inserts into the drill broke cleanly in half while I was drilling some wood. It failed right at the machined groove that retains it into the drill. Probably been used less than a dozen times, and wouldn't have expected such casual use to have it fail in exactly 5 months. UPDATE: I contacted Dewalt and they replaced the item under warranty. So, I'm glad for that. It does seem like a sturdy drill accessory. Maybe mine was just bad. If it hadn't broke, I'd give it 5 stars. I should add that Dewalt customer service was excellent.

Útil
Comprei a parafusadeira de impacto e várias brocas. Porém, não verifiquei se o encaixe das brocas e so percebi quando chegaram ambos que não batia. Esse adaptador serviu bem. Contudo, me parece que a broca fica meio frouxa. Não cheguei a testar na parede
