Question: Is the impact driver really only 1/4", it looks like a 1/2" in the photo.
Document: 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 have several cordless drill options but decided it was time to get an impact driver. Bought the combo because more drills are better. The battery life is great even with the lower amp hours I got 1.5. Power is awesome, drilled and drove lag screws into oak 4x4s all day long. The only glitch that I don't like is that the drill chuck seems to loosen by itself pretty regularly.
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.
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.
Very light, the batteries charge quickly and hold a charge for awhile. I like the LED's lights in the front. They really help light up where I'm drilling. I kinda wish for the price of these drills that they came with a hard case but they didn't. I guess thats just a personal preference of mine.
I also like the built in LEDs to light what you are drilling/screwing/driving. Very nice feature. Good power even when boring large holes with spade bits. I can't really add anything new that hasn't been said before. If you are on the fence about this set I highly recommend them. After using them for the first job or project you will be kicking yourself for waiting. Especially if you are doing overhead work.
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.
I would have preferred Makita but since it was priced really low, I gave it a try. Just finished replacing 2x6 decking boards with the drill, have no complaints with how the drill and impact drill worked. I would be 100% satisfied with this Dewalt combo set but only give 90% or 9 out of 10 rating. Comes with nylon bag and it is just not going to protect my tools in the long run.
I've only demo'd the product and have not worked with it extensively yet. Will update the review later, if possible. This is my first DeWALT product and it won't be my last!Features I like initially:* DCD790 Chuck seems very tight. Driver is speedy and has lot's of torque (in both low and high settings). Work light very bright at bottom of driver handle. * DCB203 Charger is quite fast at charging battery from 0-max (40 min.
Great drill so far. Powerful, lasts long, and great ergonomics. Have not found any negatives yet. Have not used the impact driver yet so can't comment on that.
Answer: yes
