Built for stubborn wheel nuts and suspension bolts, this cordless impact wrench combines a brushless 21 V motor with 850 Nm of maximum torque. The kit includes a 4.0 Ah Li-Ion battery, fast desktop charger, three deep Cr-Mo impact sockets, a shoulder strap with carabiner, LG 2 gear grease and a protective carry case, so work can start straight out of the box.
- Applies up to 850 Nm via a hardened 1/2" square anvil, driven by a heavy hammer delivering up to 2700 IPM.
- Adjusts between Low and High speed ranges (0-2400 RPM, 0-2700 IPM) with a single button on the control panel.
- Holds the loosened nut: rotation stops automatically in reverse, and the quick-stop brake halts the spindle in under 0.2 s.
- Fits deep over recessed wheel bolts on alloy and steel rims with 17, 19 and 21 mm Cr-Mo sockets that spare the rim edges.
- Protects the 4.0 Ah cells against overheating and overcharging with a BMS, plus a 4-LED charge indicator.
The brushless drive has no carbon brushes, so there is no sparking, less heat build-up and up to 40% energy saving – more bolts per charge. A vulcanised rubber anti-slip grip resists oil, petrol and workshop grease, vertical weight balance reduces wrist strain, and the wide battery base keeps the wrench standing upright on the bench, with or without the battery. Japanese LG 2 synthetic grease is applied at the factory; refill it after roughly a year, or every 6 months with intensive daily use. All parts sit in foam slots inside an impact-resistant case with thick clips. A strong upgrade for any garage – order the set before the next wheel change.
