Heavy DutyShopello TorqueMax 400 Cordless Impact Wrench
Perfect for
400 Nm cordless 1/2 inch impact wrench for wheel nuts, suspension work and stubborn bolts.
Accepted payments
The TorqueMax 400 is the tool that ends the four-foot breaker bar. With 400 Nm of torque and a 1/2 inch square drive, it cracks wheel nuts at the recommended 110 Nm without a warm-up, and it will shift hub nuts, suspension bolts and rusty exhaust clamps that a hand ratchet simply cannot. A variable-speed trigger lets you start a nut gently and then lean on it, and three torque modes including a reverse loosen mode give you control rather than one violent setting. The brushless motor is more efficient and quieter than a brushed equivalent, and the built-in LED lights the arch you are working under. The kit includes two 20V 4.0 Ah batteries, so one charges while the other works, with roughly 30 minutes of continuous use per pack and 60 minute charging on the fast charger. The composite body weighs 1.6 kg with the battery fitted, and everything lives in the supplied blow moulded case that sits neatly in a boot or under a bench. Every kit includes the impact wrench, two 20V 4.0 Ah batteries, fast charger, four impact sockets (17, 19, 21, 22mm), extension bar, blow moulded carry case and manual, backed by a two year warranty with free UK delivery and 30 day returns.

Very capable tool
The torque is there when you need it and you can be gentle on small bolts. It's bulky around tight engine bays, so I still reach for a ratchet there. Great for wheels and anything underneath.
Rusty exhaust clamps gone
Was ready to cut the clamps off the exhaust, this undid them with a bit of patience. Being 1/2 inch drive it takes all my existing sockets, which is why I chose it over a 3/8 kit.
Bought for my son's first car
Wanted something safe and manageable rather than a breaker bar for him to swing on. It's simple enough to use and the case means it lives in the boot without rolling about.
Comparable to the big brands
I've used a well known brand at work at twice the price and this isn't far behind. Brushless motor is quieter and the trigger control is smooth. Sod of a job doing the family's winter wheel change, now it's easy.
Heavy but worth it
It's a serious bit of kit, so it's not light above your head for long stretches. For anything at ground level or on wheels it's brilliant. Case keeps everything tidy in the garage.
Sorted my suspension rebuild
Used it on hub nuts and drop links that were seized solid. Reverse mode walks a stubborn nut out rather than shearing it, which saved me a drill-out. LED is bright enough to see under the arch at night.
