Rank #5 in Best Angle Grinder 2026: 10 Ranked, and the Wattage Claims That Fail
DEWALT DCG406N-XJ 18V XR Brushless Angle Grinder, 125mm
Price and rating as shown on Amazon when we collected them. Both change.
The DEWALT DCG406N-XJ is a 125mm cordless angle grinder that takes fifth place in this guide. It is an 18V XR brushless model with a 9,000 RPM motor, electronic brake, electronic clutch, and a two-position side handle. The listing quotes a price of £136.47 and a rating of 4.7 from 530 reviews.
That same listing also carries figures that do not match an 18V tool. The wattage field says 3,600 and the horsepower field says 1,000 — numbers no 18V battery can produce. The item dimensions are listed as 3.37 metres long, 1.25 metres wide and 1.56 metres high. Everything on this page comes from the Amazon product listing, not from our own testing.
