Bought this only because I have multiple products that use the same battery from Worx. They all have worked great, and this drill/driver didn't disappoint. Has been a great addition and I personally think it will replace my DeWalt set at some point. I am already noticing that I choose this over my other drills/drivers every time. Great buy. Shoot, I found Ace stores starting to sell Worx products. Worx is really getting popular! Great Job!

4.0 out of 5 stars Nice solid home drill; plenty of power, lightweight, comfortable.
Reviewed in the United States on April 16, 2018

I like almost everything about this drill. Almost.
The weight is very good; lightweight without feeling cheap.
The trigger is solid, it is easy to feather it for slow starts and it doesn't wobble.
I really like the chuck-lock. Most auto-chucks require you to hold the chuck while using the trigger to tighten or loosen. With this chuck you activate the chuck lock by rotating the lock, blue ring just behind the chuck, about 15 degrees right or left and it automatically opens/closes the chuck. It took me a bit of getting used to but I'm a real fan of this feature. It seems to lock the drill bit in solid but i have yet to test it in a situation where the bit might grab, such as sheet metal.
Like any good 20V Li-Ion battery it holds plenty of charge. I set about 40 wood screws, #8 or #10 x 2-1/2 or 3", in pine and oak with no noticeable loss of power.
It has three operating modes: Screw, which uses the AI torque control I discuss below; Drill, which has no torque controlled stop - if the trigger is pulled it drills; and Pulse which gives short pulses of power and I could see being very handy for removing old screws. The only issue I've had with these is operator error - forgetting to set it back to 'screw' after drilling pilot holes.
So far I've only used it in full daylight but I can see that the LED, mounted just above the battery, will be handy when working under cabinets or in crawl spaces. The whole thing even shipped with a pretty sturdy canvas bag.
The one thing I'm not sure I like is the AI torque control. It is supposed to sense when the screw is set to the right depth and then stop. So far this is has had mixed results. For most of the screws I've driven it stops when the screw is ~3/4 driven. It restarts with no issues with another trigger pull. Most of the screws are set with the heads fairly flush with the face of the wood but sometimes, like when I am driving through pine into oak, it wants to pull the head into the top board. I have yet to try this on any fine screws into delicate wood but I could see it over-driving the screws if the operator is not careful.
I'm not foolish enough to rely on this type of tech all the time but it is a major feature of the tool. Even the classic torque settings on regular drills are not foolproof and rely on operator skill to use the tool to best effect.
Overall I am happy with this unit and I would recommend it for the home hobbyist or DIY and well worth the $68 tag. I'm not ready to recommend it for a work environment just yet.

5.0 out of 5 stars Best drill I've ever used so far
Reviewed in the United States on October 23, 2018

I used to have a bulky, corded Black & Decker drill with a chuck key, and man, that thing was cumbersome. So, I decided to replace it with a 12V Black & Decker cordless drill with a keyless chuck that was fine for small around-the-house jobs, but was lacking in power and battery life. Finally, I arrived at this Worx AI drill, and it completely blows those other two drills out of the water. It's very powerful and the battery seems to last forever. The LED light is a nice touch, but what I really love is the Bitlock feature. It's so incredibly fast and easy to change bits! This means it's really easy to switch back and forth between drill bits and driver bits if necessary, and I've never had a problem with the bits being off-center or unsecured.

On one hand, I'd sort of like to have a clutch for drilling screws, but switching it to the "screw" setting is good enough. It stops and begins pulse-assist when the torque gets too high, which is essentially what a clutch would do anyway. For big jobs that require a lot of screws going through a lot of wood, I'd recommend an impact driver instead of a drill, but you can't drill holes with an impact driver, so if you can only have one, this is a fantastic choice.

Love the drill, have used this thing for so many projects. Only issue is the chuck seems to have moved or something happened as there is a slight wobble to it now.

Wish I could replace the chuck, as I loved this drill.
