  1. R Granada

    What’s not to like about this power drill? It has a hammer function, 3 speeds, LED Light, metal bit holder (can’t think of the actual name of it right now), ergonomic and light weight. This unit was the tool only and didn’t come with a battery.This drill performs flawlessly and the bit is straight with no wobbles. The trigger is pressure sensitive and it includes a little clip to hold onto your belt if you want.

  2. Mara Wells

    This is a replacement for a previous Dewalt drill that reached the end of its service life. The old batteries fit this new drill well. Love the LED light feature so I can see the target much better. Drills fine. If I want to get serious, I will pull out my Dewalt corded hammer drill. But for convenience and 90 percent of most around the house drilling duties, this one is fine.

  3. C. M.

    Upgraded my 12 year old NiCad 18v to this and am very impressed. FAR more torque and probably 4x the RPM’s and even more ergonomic than the older version. All steel chuck is really nice until you accidentally hit it at full speed and burn your hand so be careful there. The light is more handy than I first gave it credit for. Only downside is the batteries are WAY overpriced so save a bunch and get a generic.

  4. Dan Nickels

    I had the Exact same drill for years and it worked PERFECTLY building tons of decks, etc.Then I dropped it about 20 feet off of the ground and it died:( So I ordered this same model.I Love the drill. It has two speeds both of which are operated by a variable trigger. This little guy has screwed WELL OVER a hundred pounds of exterior screws and showed NO degree of slowing down (Until I dropped it).There is also an led onboard that lights up where you are working [This One detail you will immediately fall in love with]. It has a brightness level and auto times out after releasing the trigger.It also has a hook which will hook onto a belt, etc….I’ve ALWAYS just used my jean pocket to slip the hook into.Feel funny saying again that I LOVE this drill but I just do. It’s been a major workhorse.

    An excellent drill and driver. It’s lightweight, compact and powerful. I also bought a 4Mh battery, which I can use on other Dewalt tools, and a charger which does a fine job. The drill has a lot of torque settings, and the light is directed onto the subject perfectly. It also stays on a few seconds after pressing the trigger, which is handy.

  6. brian

    Far better chuck, love the option to choose light settings. The clutch seems far stronger/ blew clutches on two original designs. Rubberized impact zones. I’ve put it thru it’s paces building a new steel pole barn. Very satisfied, take the battery stars as you will as I purchased the bare tool but am still going strong on my first gen batteries.

  7. Jonathon

    After owning cheap brushed motor drills, I’ve been very impressed with this DeWalt. I cannot believe how much torque the brushless motor puts out.The battery life is spectacular. Even the small 2Ah batteries will last incredibly long. I really appreciate the LED light in the base, although it inevitably casts some shadows.I hope it holds up.

  8. CRS

    The first one I received must have been a defective unit, I drilled 3 holes with a very small drill bit into my stainless steel toolbox to mount some handles and it froze up. After trying to free it for a while without resolve I decided to have amazon send a replacement unit. This is one main reason to shop amazon, the replacement came within 2 days, couldn’t believe how fast it was here, I boxed up the old one and shipped it back immediately and they let me know when it was received and credited. The new unit has worked flawlessly and I have put it through its paces. with a lot of holes and driving a lot o screws , not issues yet and I don’t expect to have any. the drill is solid.

  9. Kevin Adams

    The Dewalt 20V drill I was using was very powerful and a big step up from the old 18V drill it replaced. But this drill is a major step up in torque from my other 20V drill and powerful enough get you in trouble if you underestimate it.My one complaint is that it is amazingly LOUD when using the hammer drill setting.

    The media could not be loaded.  Awe some drill. Battery lasts forever. Watch my video to properly install drill bits to ensure they never come lose.
