Rank #9 in Best Cordless Impact Wrench 2026: 10 Ranked, Torque Claims Checked
TaskStar 1/2in Brushless Impact Wrench, 1200 N·m, 2 Batteries
Price and rating as shown on Amazon when we collected them. Both change.
The TaskStar Cordless Impact Wrench is a 1/2-inch drive, 21V cordless gun that sits at number 9 in this guide. It costs £84.99 and carries 4.7 out of 5 from 55 ratings. Its headline claim is 1200 N·m, written in the title as 1200N·m(900ft-lbs) — 1200 N·m converts to roughly 885 ft-lbs, so the bracket is a rounded-up version of the same figure. Worth noting: the first bullet calls that 1200 N·m the breakaway torque, the number for undoing a seized fastener, and no tightening torque appears anywhere in the listing.
What makes this entry worth reading is that the advert does not agree with itself on size. The bullets describe a tool at 3.96 lbs with a 6.46-inch body, which is about 1.8 kg and 16 cm. The specification table in the same listing gives an item weight of 5.34 kg and an item length of 42 cm — roughly 11.8 lbs and 16.5 inches. That is around three times the weight and more than twice the length quoted in the marketing copy, and both numbers come from TaskStar's own page. Everything below is taken from the Amazon listing; we have not tested this tool ourselves.

What buyers actually say
Quoted from customer reviews on Amazon
Verified purchase“Bought this to undo hub nuts on my Fiat Ducato 130 van. These are torqued to around 500nM. Fitted a 46mm socket to the impact gun and held it on for a few minutes. At first i didn't believe it would work. Then the nut slowly began to move. Brilliant.”
Verified purchase“Very impressed so far. Looks great feels great and works well. So far the hardest bolts I have removed with ease were 140nm . I did them back up on setting 3 and it took them to a higher torque in seconds.”
