Question: May I use 20V 4 Amp H, instead of 2 Amp H ?
Document: Also be careful using the standard chrome sockets. If you will be requiring a lot of torque, you may consider getting &#34;impact&#34; rated sockets. I say &#34;may&#34; since this impact driver does not have the torque of 3/4&#34; air powered impact wrench.
Whether it is for the DIY'er or Jack of all trades, this set is perfect.I found that the DCK286 20V Max is perfect for me.I have not had a chance to use this on any major projects yet to test the limits of the Drills, but I will update this review when I do.Note:If you are not familiar with impact drivers, they are great tools, but be aware there are somethings that you need to know.
After reading reviews on the various 18v and 20v sets out by Dewalt, I decided to upgrade from my 5 year old Makita 14.4. It's been a tough little set, but didn't quite have the power co-workers had with their 18+ equipment. I must say I'm VERY pleased with the power, lightness, and battery life after a couple of weeks as handy man tools.
The impact driver and hammer drill that came package are by far the best two tools iv'e purchased in the. The power that the cordless 1/4 inch impact has was unbelievable.
I choose this rating because I use these tools everyday and they hold their charge for days and the torque is amazing I couldn't ask for better set of drill/driver combo
I use these drills often at work and put them through some tough tests. There is not one fault I can find with either drill and would highly recommend them to anyone. Each drill is very light and balanced with a lot of power.
Dewalt did it!!!! Fantastic products--small-light-powerful-excellent chuck & clamping of bits. Note that this 20 volt brushless kit has the smaller & lighter compact hammerdrill--greatly preferred for my use. Only regret is I did not have these two products  years ago.
I had to replace my old Makita drill/driver and I have always appreciated Dewalt quality. I held back because I didn't understand the use of the impact driver. After some research I made the jump to this unit, also pleased to get a brushless unit.I've only had one chance to use the impact driver so far but I was very impressed with its ability to handle the job.
Pre drilled everything with the driver and drove the 3&#34; screws in to the 2x4s with the impact. I'm far from a woodworker, and thought these things would be overkill for my use, but after using this set, I know now just how valuable a good set of tools really are. Absolutely in love with these things.I used this set all day (8 hours in total) and the impact got most of the job duty for the day.
My husband bought this drill. This is his review...I have been using a Makita 12V drill for the past 12 years. It has been very reliable; it is too slow and lacks the torque I need for drilling 1/2&#34; holes in wood and metal, though. I decided I wanted something with more power and speed, and still be compact.
Answer: yes
