Rated 5 out of 5 by from power a plenty I have bought this DeWalt driver to use for the bigger screws and bolts for heavy duty woodworking projects and wow does it do the job the only problem is you have to be very careful when using the 3rd speed setting its lighting fast and with so much power to can a drive a 6 inch screw straight through a two inch timber no problem

Rated 5 out of 5 by from Different league to Clarke Used to have a Clarke impact wrench of which the charger failed. Bought this one to get me out of a hole. The difference in every part is amazing. More than enough torque for removing wheel nuts.

Rated 5 out of 5 by from Beast!! Bought this gun as a bare unit along with a 4ah battery as it fitted my existing 10.8 volt charger, so far its been excellent, will remove 32mm truck wheel nuts and haven`t found anything it won`t shift yet, with the 3yr Dewalt warranty (when you register it online) and the great Screwfix price, You can`t go wrong.

Rated 5 out of 5 by from Weapon Extremely impressed with the power of this driver. Removes anything I can put in front of it. It's a little heavier than others but not an issue.

Rated 5 out of 5 by from Dcf899 Magic bit of kit, works like air wrench in my garage, will carry with me all the time

Rated 5 out of 5 by from Great tool honest review! Ordered gun over the phone had it delivered next day and recieved it before 11am brilliant service from screwfix. The gun is a little heavy but compared to an air type its around the same if anything alittle lighter but does feel more balanced once a battery is clipped in the build is solid and everything feels well built only used it to test it out and its got alot of power wheels nut are not an issue with this gun, cannot comment on reliability and use over time though it has got a 3 year warrenty if you register at dewalt. I opted for the detent pin over the hog ring as you can use it two ways lock it onto the socket or just slide the socket on without lining up the holes my big worry was taking the sockets off when using the hole in the socket and the anvil pin but i can say i have tried all brand new bergen bluespot halfords us pro and they all pull off easily was watching youtube vids were people make it look hard its really not. The hog ring design is harder to push on and off untill the little o ring wears but when that happens you have a chance of the sockets flying of and hitting someone or something. Overall im really happy with it and its going to be a big time saver when i need to change the wheels on the car.
