Sealey CP3005

Best price: £342 | Battery: 18V Li-ion

Part of Sealey’s Premier range, this wrench really packs a punch and is rated up to 650Nm – most here are around half that. No surprise then that we’d barely pulled the trigger before the test bolt was spinning. The price you pay for that grunt is weight, although the CP3005 is quite well balanced. We tested the new-for-2015 V2 with high-capacity 4Ah power packs – up from the 3Ah of the previous version – although we’re told there should be no price difference so our price is for the older kit.
