Rank #3 in Best Impact Drivers 2026: 10 Ranked, and Why the Torque Number Lies
DeWalt DCF850N-XJ 18V XR Compact Brushless Impact Driver
Price and rating as shown on Amazon when we collected them. Both change.
The DeWalt DCF850N-XJ sits third in this guide, and it is the odd one out among the tools ranked above it. Where the ONEVAN, Dong Cheng and DCA listings each print two torque numbers — one for loosening and a smaller one for tightening — this DeWalt listing prints a single figure, 205 Nm, and uses it for both the Maximum Torque and Torque fields. Whatever gap exists between cracking a seized nut and holding a fixing tight, this advert does not tell you, because it only ever quotes one number.
Where the DCF850N's own fiche goes wrong is elsewhere. The spec table lists Item Weight as "1 g" while a product bullet says 0.95 kg for the tool alone, and the Battery Capacity field reads "18 Volts" — a voltage, not a capacity. The Item Dimensions field gives 8.2L x 5.5W x 15H centimetres, while a bullet quotes a 101 mm length for the same tool. It is a bare unit at £99.95, rated 4.7 from 1,099 ratings. Everything on this page comes from the Amazon listing rather than from any testing we have carried out.
How those 1,099 ratings break down
An average hides its own shape. This is the spread behind the 4.7 stars.

What buyers actually say
Quoted from customer reviews on Amazon
Verified purchase“Absolute belter of a tool! 100% recommended. Tons of torque (so beware cheap bits and screws - you'll shear them off) is a tiny package. It's become my go-to daily driver (pun intended).”
Verified purchase“Feels strong good torque very light even with 5a battery in. Dewalt usual great quality”
