- Reviewed in Canada on February 11, 2025Verified PurchaseWow this impact is the best tool i.ever owned very powerful took the lugs off with no effort at all useing my 5 ah battery, and when tightening the lugs I just hit the trigger for one second when the nut was against the rim I then grabbed a socket wrench to see if I move the nut in.the tightening position and could not budge the nut this dewalt impact is sick, I highly recommend this gun.

- Reviewed in Canada on July 2, 2024Verified Purchasehard to get socket in and out ???
- Reviewed in Canada on June 14, 2025Verified PurchaseYou don't need a mid range wrench with this thing, it's putting out incredible numbers, it says 450 nut-busting but this thing is more in the 500 to 550+ depending on the battery.. I put a 6ah flexvolt on this and it's taking off lugs it has no business doing, I can just Imagine the torque numbers with the new 8ah powerpack batteries

Reviewed in Canada on December 3, 2024Verified PurchaseTrès léger et super performant..; la pose et la dépose des pneus est rendue une corvée moins pénible.!
Bon prix et reçue chez-moi en 48 heures..!
Nice DeWalt as usual....
- Reviewed in Canada on January 9, 2024Verified PurchaseWhat a great little impact! Just finished boring some 2 1/4 holes through some rafter blocking for attic vents. Chews through in no time. Just needed the quick change adapter- 1/2" square to 7/16 hex. Make sure to get the detent pin version so it holds sufficiently when removing the bit from the hole.
Also is perfect for driving timber screws, lags, etc.
Makes quick work of running wire through studs and joists too when paired with a self feeding auger bit. Fits nicely between floor joists even with the 1/2 square to 1/4 hex adapter.
I do have the dcf899 which has been great, but honestly haven't used it since I got the 922. Also incredibly useful on the car, tucks in nicely to access various stubborn bolts!

5.0 out of 5 stars Amazing tool!
Verified PurchaseIt’s a great impact gun. Incredibly powerful for its size. The fact that it slows down after a nut loosens is fantastic.
My only complaint is that it’s very difficult to get a socket onto it. I have the Hog Ring Anvil Model (DCF921B), and perhaps the problem is my sockets, but getting them onto the gun is nearly impossible at times. Very annoying.

Verified PurchaseAl principio no contaba con batería para ponerlo a funcionar ya que adquirir las baterías superó mis espectativas al utilizarlo para retirar birlos y tornillos con demasiado torque

5.0 out of 5 stars Dewalt created a beast
Verified PurchaseThis little impact wrench is a beast, and the shipping was great; I got it sooner than I thought. Glad I found this tool, it was exactly what I needed to replace my tractor Tiller blades.
