Dewalt is coming out with a new 20V Max li-ion brushless cordless drill driver, model DCD790, which will be released alongside the also-new brushless hammer drill that we previously discussed. While some might look to compare this model to Milwaukee’s FUEL M18 brushless drill, it is worth remembering that Dewalt designed the DCD790 to be more compact and lightweight. The new drill also features a foot-mounted LED worklight, a la Bosch and Ridgid’s designs, for fewer shadows.
Marketing images show that the DCD790 is shorter than other top brands’ competing models, but it is also substantially less powerful. The new brushless drill (center), hammer drill (right), and what looks to be a new impact driver (left, model DCF886). If I could only work with one cordless drill, I would probably pick a more powerful compact 18V drill over this one. That all said, the DCD790 will surely be popular with users that mainly drill and drive smaller or shorter holes and fasteners. Im interested in hearing about the specs of the new brushless impact and the reasoning behind it. But my guess is that the new impact driver shares similar design and construction elements with the new brushless drills so that the same brushless motor could be used in all three tools. I am so impressed with Dewalts impact driver that when money allows I will get this for drilling into steel at work. So you can’t really rely on on-paper specs, nor is it easy to rely on head-to-head comparisons. It’s easy to create comparison tests, but I have yet to find a way to interpret results with high enough confidence. At this point it doesn’t really matter that Dewalt adopted their own metric, now that some li-ion-powered tools shut down before they even get to the max-torque shutoff.
Michael if it was the case that dewalt was trying to hide something don’t you think they would have picked a system that made their numbers look better instead of worse? It’s hard to say, but during testing there were times when I wished the 780 was *just a little bit* more powerful. Direct comparisons are incredibly complicated, especially now that li-ion batteries typically have built-in protection. There is no public UWO to in-lbs conversion, but I believe that the multiplication factor seems to be somewhere between 1 and 1.5. I believe I once read (or was told) that they adopted UWO because it allowed for a true measure of power between different Dewalt models, while in-lbs relates to no-load torque. While tool specs have less meaning than they used to, many buyers rely on them when buying new tools. With PCs it used to be processor speed in GHz, with digital cameras it was the number of megapixels, and with LED flashlights it’s lumens.
I read a while back on the dewalt website that one reason for the UWO measurement was to compare cordless tools to corded tools.
On the other hand the light does now illuminate the tip of the bit, unlike the DCD780 which got in the way of its own light. We have received numerous tips that the DCH253 is powered by a brushless motor, but have yet to receive official comment or clarification from Dewalt. Aside from a couple of new vent placements, a slightly different motor casing, and a higher price, there does not seem to be any major differences between the DCH213 and DCH253 rotary hammers.
Vibration dampening on the DCH213 is excellent, and I can’t see any way that Dewalt could have improved upon it further.
One thing I am happy to see is that the mode-select markings are high contrast yellow-on-black. Anybody has tried to compare the Bosch Cordless Rotary Hammer GBH 18V-EC with the Dewalt DCH 253?
For a detailed overview of the Ryobi Auto Hammer, check out our preview post from when it was first released. Upon opening the Auto Hammer’s box, we found a very nice soft case with velcro straps and mesh pockets, similar to the case included with the previously reviewed Milwaukee M12 drill. Before we get to talking about the actual operation of the tool, we wanted to point out a few key features, mainly the magnetic nail guide and retractable sleeve. The retractable sleeve moves in and out relatively smoothly, and retracts beyond the operating position of the hammer’s anvil to ensure that nails can be driven flush to the work surface. There is also a white LED above the trigger and below the anvil that helps illuminate work areas. The absolute first thing that we noticed is that there is no safety switch, only the trigger. The first thing we noticed was that the Auto Hammer is very loud, well beyond the point at which hearing protection is optional. It is important to note, however, that individual strikes by the Auto Hammer do not seem to be substantionally louder than those by a manual hammer.
If given the choice between the Auto Hammer and a nice sized framing hammer to drive large nails, we’re going to go with the manual framing hammer. When driving smaller nails, though, the Auto Hammer works beautifully well, and is almost a pleasure to use. There were many things that we liked about the Auto Hammer’s look, feel, and overall quality.
Ryobi’s Auto Hammer is a well built tool with subtle details and features that make it very user friendly, or at least until one tries to hammer in some large nails. We would recommend Ryobi’s Auto Hammer as a considerable option for those looking to primarily drive finish nails or smaller common nails in tight spaces.
By no means is the Auto Hammer a bad tool, but it is of more limited realistic use than we would have liked to have seen. At $59, Ryobi’s Auto Hammer will definitely be more appealing to potential customers than it was at $90, and this should also give it an edge against the nearly identical Craftsman Auto Hammer. Ryobi’s Auto Hammer is typically priced at $90 at The Home Depot, but it appears to have dropped in price recently to $59. I was looking forward to buying one of these Auto Hammers next month for a project, and your review came at a great time! It could just be that some stores are trying to clear out excess stock that’s left over from the 2009 holiday shopping season. The Auto Hammer is not the answer to everything, but definitely useful in tight spots with new wood.


Works really well driving in NMD cable staples in cramped areas between joists; once I figured out I could hold the staple in position with a magnetic pickup tool instead of my fingers. As you might recall, Milwaukee is coming out with a new M18 Fuel compact drill and hammer drill. This isn’t terribly compact or lightweight, but it does give Milwaukee a slight edge over the competition. Milwaukee’s current same-class non-Fuel M18 hammer drill can deliver 525 in-lbs of torque. Head to head comparisons can be misleading as well, making it difficult to determine if one tool is absolutely better than another. I have to completely agree with you regarding the Dewalt 20V tools in terms of their ergonomics, balance, and grip. Torque delivery is also a function of being able to hold onto the tool as it tries to break your wrist, I always get a chuckle out of folks who try to use a cordless tool or even a corded tool with a wimpy side handle to drill a pipe clearance hole with a big self-feed bit.
I agree – unless an objective 3rd party is the one publishing torque ratings, I take the claims with a grain of salt. Now, even on the owners manual and the package front the chuck looked just like the ones you see on the website.
The truth is you don’t need all that torque with impact drivers delivering massive torque without twisting your arm off there is no need for anymore then 400lbs to 500lbs of torque.

Sds drills « singletrack forum : My cheapo aldi sds drill finally packed in (motor pinion stripped). The kit comes bundled with their new 2.0Ah li-ion batteries that provide up to 33% more runtime with 50% longer recharge time (45 mins vs. If Dewalt didn’t change the balance or handle profile too much, the ergonomic should be great as well. And if I could only work with two, I would pick a high performing compact and lightweight 12V model (such as the brushless Milwaukee M12 Fuel), and a more powerful compact or heavy duty 18V model.
The DCD790 builds upon the 780’s strengths with a couple of improvements, most notably the brushless motor and metal chuck. I couldn’t get used to the bit release mechanism and put off a lengthy testing session for so long because of this that the sample got buried somewhere.
But that doesn’t take into account that PTI member brands should all be following the same testing methodologies to ensure fair and honest torque comparison.
UWO is almost impossible to calculate and they are the only company that has been doing this type of measurement. When viewing drills side-by-side, customers will see and think that 650 in-lbs is better than 600 in-lbs, even if lesser specs would suffice for their needs.
Ignoring everything else, what would you rather buy for $150, a 650 in-lb drill, or a 600 in-lb drill? I couldnt find what I remember reading but heres an article listing why they chose UWO as a more reliable rating system over torque measurements.
The new rotary hammer is rated as having the same power as Dewalt’s DCH213, and also features active vibration control for improved user comfort. If I had to guess, I’d say that the new model has been redesigned on the inside for greater efficiency and runtime. The markings on the DCH213 are not terribly difficult to read, but the DCH253 markings look leaps and bounds clearer. Judging from the Amazon reviews and your comparison of the two models, I should be happy with my purchase. It’s worth checking back, though, as Home Depot has reanimated deals a couple of times in the past month. The hammer setting on the compact hammer drill can be turned off via the adjustable clutch.
I went to use it today, and killed the battery removing a few screws from a door panel, and drilling a few holes. In fact, Ryobi claims that with their new Auto Hammer, hammering has never been easier. With claims like these, we just had to put the tool to the test! Ryobi includes a single 12V lithium ion battery and a dual chemistry charger with the tool. There are a few smooth surfaces, but the majority of the tool is covered with a soft rubbery texture that allows for a comfortable and secure grip.
For this type of use, the magnetic guide does a decent job for smaller nails, but larger nails will pop out, pivot, and then stick to the face of the retractable sleeve. The LED emits a fairly bright and broad beam, but it won’t be mistaken for a standalone work light or headlamp. However, after a few squeezes of the trigger, we realized that the hammer’s anvil will not engage unless it is in physical contact with and pushing down on a nail.
Instead,  it is the rapid succession of impacts that is almost intolerable without hearing protection. Yes, this would require greater physical exertion, but at least then we’d be able to work at a more comfortable pace.


The tool is still quite loud, and we still feel vibrations transmitted to our hands, but to a much lesser extent. It had great ergonomics, and there a few minor touches that we appreciated: the included soft tool bag, the 12V charger with indicator LEDs  and a legend to help diagnose charging issues, and the slim lightweight 12V battery with its nice grippy bottom.
Attempts to drive 16D common nails resulted in extreme tool and hand vibration that cannot be comfortably sustained for too long. For those looking to drive many larger nails, we would instead recommend alternative options, such as pneumatic palm nailers or nail guns, or hose-less electric and powder actuated nailers.
I don’t plan on using it on big nails, and the lower price does make it an easier sell.
That’s a pretty decent price, and might even be low enough to convince skeptics to give the Auto Hammer a try. I’ve seen tests where one drill leads the pack when used with certain bits and trails behind with others. It seems all of the companies came together to agree that the PTI standards of testing were fair, but no other company will allow published testing results of their tools. In a tool test a couple of months ago, a tool with a higher torque rating conked out sooner than one with a lower rating after its current-overdraw protection kicked in and powered the tool down. In my experience people with complaints don’t understand how to use there tools or expect a cordless drill to do everything.

Read our reviews to find the Best Cordless Hammer Drill and compare photos, specs and user reviews. Packaging should be the same as what is found in a retail store, unless the item is handmade or was packaged by the manufacturer in non-retail packaging, such as an unprinted box or plastic bag. Import charges previously quoted are subject to change if you increase you maximum bid amount. That particular Bosch compact drill is conveniently left out of Dewalt’s size comparison photo.
What role does the new one fill when they already have 2 outstanding impact drivers (brushed and brushless)? For example, a drill’s performance can drastically change depending on which battery is used. In one case, a higher-rated model shut off and a lower-rated model kept pushing until it smoked up.
Some will look at other factors, but a lot of people will go for the one with the higher rating. As discussed, I feel it’s hard to know what to think now that a lot of tools shut themselves off way before they stall. The new grips are fatter and the trigger is farther away: both negatives for my medium hands. Overall, based on appearances and feel alone, the Auto Hammer’s review was off to a great start. The Auto Hammer is rated at 3600 BPM, but we could not verify if this actually translated to 60 strikes per second. In further tests with a better clamped workpiece and while testing larger nails, the vibrations were transmitted to and throughout the supporting table, and when tested indoors the vibrations were felt in the next room.
Logically, smaller or thinner nails proved to be much easier for the Auto Hammer to drive than the larger ones. Note that the 2602-22 is weighed with an XC extended-capacity battery, and the 2604-22CT a compact M18 battery. I like the 20v max grip its extremely comfortable, Makita batteries charge super fast and the tools just last. If you reside in an EU member state besides UK, import VAT on this purchase is not recoverable.
This is further complicated by how some brands have updated their tools and battery packs without changing the model numbers. The shape is similar and would still be excellent if my hands had grown from medium to large, but my hands remain the same so the new grips are too big.
With the 3-jaw chuck you can use the rotary hammer (in rotary-only mode) with traditional twist drill bits as you would with a drill or hammer drill. If you’ve ever used a hammer drill, these vibrations are stronger and more exhausting. I was worried I got dupped by maybe some gray market crap, even though I got it from a big box store.
Torque ratings always seemed to be skewed by the manufacturers, along with RPM’s and other ratings. Do you really think that Ridged’s impact is more powerful than everyone else on the market at a almost $100 lower price point?
If you run the vehicle in the red all day every day your vehicle just isn’t going to last.
I believe UWO is a better gauge of how fast a tool will perform most applications than just listing torque because it takes into account RPM as well. If you have the extra gap in torque between general use and maxed out rating your tool is going to last longer, period.
