I have a large Makita 18V hex impact driver now but it ***** for driving screws.
Looking at the Makita CX203SYB set but the driver doesn't have any torque adjustment.
It seems like I've seen a Makita impact driver that has the fluid-drive system -
the one in this review might be what I'm thinking of.
+1 for Makita.
3 LXT (18v) Makita's I'd suggest would be:
Makita XST01Z- This is a "oil impulse" impact driver and is very quiet in comparison to a regular impact driver. Adjustable power settings, but no clutch. That said, I've dialed mine in perfectly over the last year and I love this tool for light/mild work. Might be overkill for you as a dedicated screw runner. The oil impulse units from Makita are favored by many because of lack of noise they generate indoors on job sites. If you have ever had your head burred inside hanging cabinets all day with a regular impact, you will love this tool. It's also very, very smooth.
Makita XPT02Z - This tool gets hate for being underpowered for an impact driver, but I argue it's perfect for 99% of homeowner needs. There is plenty of adjustability for this to be your go-to screw gun and more. There are
very few other options in this tool space, but this is a do it all type of tool, with a screw gun, impact driver, drill
and hammer drill all in
one tool. I love mine and it's my go-to for general purpose repairs around the house. It's not a cheap tool (made in Japan) but unless your looking to do construction work with it day in and day out, it's a good buy.
Makita DDF083Z - This is probably your best option, but not easy to get in the USA. It's basically an LXT 18v, brushless 1/4" hex screw gun with a clutch. I had to get mine from eBay (from the UK) and it was about $200 shipped (bare tool). Makita makes another version of this for the US market but it's not brushless. If I just need a screw gun and maybe some light drilling (1/4" hex drive drill bits), this is the tool. It's light, fast and the battery lasts forever. It's way powerful for a screw gun, but the clutch settings are easy to use and adjust.
The above are all gun style drivers. Makita makes several "pen-type" drivers as well, even an impact rated one.
