Great product
I got this product as a gift, and I am so happy that I did because I use it more than any other tool I have! It is very strong, lightweight and the battery lasts forever! It is one of the most helpful tools I have in my house!

Absolutely the best!
If you are not sure about purchasing a Greenworks product, don't think twice! They are absolutely the best power tool we have ever owned! I have 3 drills including an impact, a blower and I also have the 2000 psi pressure washer! They are the best!!

I liked this drill so much I bought a second one!
I bought one of these and it is really powerful for a cordless drill. I later bought a drill and driver pair -- the driver was not a flexible chuck and the drill was not nearly as powerful, so I returned the pair and bought a second hammer drill. I often use both at once to pre-drill for screws and then with a screw bit to put the screws in. The chuck is easy, they are durable, and they are powerful.

Works great, battery interchanges with trimmer.
I recently bought the hammer drill, partly because it shares the 24V battery with a Greenworks pole hedge trimmer I got as a gift. The keyless chuck works flawlessly.
The torque/speed adjustment feature is great for specific jobs. The battery delivers plenty of power for quite a while and recharges quickly. I dismantled a VERY high "tree fort" with it, which would have been much more difficult with a "wired" drill.

Does this hammer have the function of both drilling and hammer-drilling separately? or it is just a hammer drill?
