Impact Wrench, or Impact Driver...?

[The Seer]

Done a little research into this, and so far I'm still not 100% what tool to buy.

In the coming weeks I'm due to construct a workshop from timber, and figured the an Impact Driver would be more suited to this job than an Impact Wrench...or would it?

As such and I really should have one for the garage to work on the car, I don't have an Impact Wrench. Question is will an Impact Wrench with its greater torque be suitable for both jobs and thus eliminate the need for buying both Wrench and Driver?

I'm looking at a rechargeable lithium unit as opposed to an air or 240 volt tool.

Any ideas? Thanks

An impact driver will be almost no use for working on the car. It's not really designed to loosen nuts and bolts.

An impact wrench will more likely be too powerful for screwing into wood even on a low setting. It's more likely to strip the heads off than spin them round. If it has a variable speed trigger and if your careful you could get away with it

For driving screws into wood, I would have thought an ordinary corded drill with a torque limiter would be all you need.

You’ll want an impact driver for the timber frame. Makita or dewalt will be fine.

...is the correct answer.

Am impact driver is the daddy for driving in screws. Easy to use and light in hand. Buy something cordless with a couple of batteries. I went for a Makita impact driver. Dewalt/Bosch etc will come equally recommended. None of them will be much use for working on cars.

Driver for screws.
Wrench for bolts/nuts.

I use dewalt, having same manufacturer's battery/charger helps with cost as the bare units themselves are not that expensive.

Driver will be next to useless for car maintenance.

This. I have a small 10v driver which is great for little jobs, very light. So for driving screws its fine. We bought a large wooden climbing frame for the child which needed deconstructing, moving and reconstruction on site. I bought a cheap impact wrench and it was an abolsute god send as the whole thing was bolted together.
Actually its been quite useful on other things since so I sort of wish I'd bought a better one. But better as in lighter as its torque level is fine.

I have the bosch 12v impact driver and it is great for woodworking/around the house.

I also bough a 1/2 drive adaptor and use it for like impact wrench duties. It won't shift anything tough, but ideal for bleed screws and anything that takes ages (eats spring compressors for breakfast saving loads of time).

I will likely get an impact wrench at some point, but haven't felt compelled yet.

I've just got one of these for a lot of decking work and am very happy with it

It is a lot stronger than a drill/driver for heavy woodworking. You may want to consider torx type woodscrews to avoid slippage and damage to the screwhead
