The DEWALT DCF921N-XJ is an 18V XR brushless impact wrench with a 1/2 in square drive and a hog ring for socket changes, listed at £129.00 and rated 4.6 out of 5 from 224 ratings. It comes second in this guide, and it is the most straightforward listing of the ten on the point the guide keeps returning to: it gives two different torque numbers and tells you which is which. The bullets and the spec table both say up to 406 Nm of fastening torque, while the item highlight in the same listing adds 610 Nm of breakaway torque. That is the split — one figure for doing a bolt up, a larger one for cracking it loose — that several other listings in this article leave you to work out for yourself.

What the listing does not spell out is what arrives in the box. It gives the operation mode as Battery and the voltage as 18 V, but names no battery and no charger, so the £129.00 price is not confirmed either way as the price of a tool you can put straight to work. The spec table gives 995 g and a 24 cm item length, which sits with the compact body the bullets describe, and the star breakdown shown adds up to 100 ratings rather than the 224 the listing reports. Everything on this page comes from the Amazon listing, not from any test of our own.

## Questions people ask

**Does the DEWALT DCF921N-XJ come with a battery or charger?**

The listing names neither. It lists the operation mode as Battery and the voltage as 18 Volts, and gives the price as £129.00, but no battery or charger appears in the listing details, so the box contents are not stated.

**How much torque does the DEWALT DCF921N-XJ have?**

The bullets and the spec table both give up to 406 Nm of fastening torque, and the item highlight in the same listing adds 610 Nm of breakaway torque. The listing keeps those two figures separate.

**What sockets fit this impact wrench?**

It has a 1/2 in square drive with a hog ring, which the listing describes as being for fast, hassle-free socket swaps. One reviewer notes that DEWALT impact sockets are wider than normal chrome sockets.

The spec table lists 995 g and an item length of 24 cm, with the brushless motor described as compact for tight spaces.

**What control modes does it have?**

The listing describes a 4-mode switch that includes Scaffold Mode, plus a variable trigger to adjust speed and power. A reviewer describes a mode that slows the tool once a bolt is loose and pauses briefly when a bolt is snug.

**What is the rating on the listing?**

4.6 out of 5 from 224 ratings. The star breakdown shown in the listing adds up to 100 ratings, so it covers part of that total rather than all 224.
