Price and rating as shown on Amazon when we collected them. Both change.
The ONEVAN 1/2in cordless impact wrench is the tenth pick in this guide. It is a brushless, 1/2in square-drive tool sold with two 4.5Ah batteries, a fast charger, six sockets (14mm to 22mm) and a carrying case, for £102.89. The listing leads with 1,700 N·m (1,254 ft-lbs), and that is the biggest number on the page.
The same bullet that carries the headline also splits it in two: 1,500 Nm for tightening and 1,700 N·m for disassembly. That is exactly the gap this guide is about — one figure for cracking a seized nut with hammering force, a smaller one for holding a fixing tight — printed by the same seller in the same sentence. There are smaller wrinkles too. The star breakdown adds up to 100 ratings while the page quotes 70, and the spec table records "Unit Count: 1.0 count" against bullets that list two batteries. Everything on this page comes from the ONEVAN's Amazon listing, not from any test of our own.
