What is uwo power

And how does it impact your drill? Do torque and speed have any relation? Why do experts, DIYers always prefer cordless drills with higher torque? Which drill setting can help you achieve the maximum torque?

And finally, there is something that I have prepared for you in the form of an epic cordless drill torque chart. Of course, that was a real challenge to face. But, it finally paid off…. The torque is the measurable amount of twisting force that the drill applies in an inch per pound. Which is represented as In-lbs and it is used for almost every drill.

When it comes to torque and speed, the corded drills are more powerful than the cordless ones. They are pretty famous for their ease of use and extreme portability. While on the other hand, the cordless drills torque adjustment system with variable speeds, clutch numbering, and 3-mode drilling gives you an edge on doing different tasks with a single tool.

Every DIYer, homeowner, industry expert recommends a cordless drill with high torque. Because, it makes your work precision accurate, swift, and efficient. Which means professional work.

Plus, higher penetrating power helps you drill through tougher materials just like slicing butter with a knife. This same unit is also used to measure the torque of a drill.

Thus, due to all these system usages by different brands I had to go through a teeth-grinding issue during my search on high torque drills. In this way, you cannot determine the power of these different drills which have different measuring systems just for torque. So, here I want to make it crystal clear for you. That cordless drill with a higher number always means high torque.

So, no matter which system brands or manufacturers use for the evaluation of their drills. You can do that by using our nm to the in-lbs converter. Our tool automatically converts the drills given newton meter value into inch-pounds. The opposite is also possible. For those people who check their drills torque in Nm. We also have the in-lbs to nm converter. But, sadly there is no system for converting UWO into Torque. Because the UWO collectively gives a full picture of the power and performance of the drill than the torque alone.

Another aspect factor that goes side by side with torque is speed and this speed is denoted by RPM. Thus, the total number of turns completed by a drill within one minute is called RPM. Both torque and speed RPM are inversely related to each other.

If one increases the other has to be decreased. The cordless drills have a separate setting for adjusting between torque and RPM. This setting is known as the speed setting. Most drills have 2-speed settings but there are other cordless drills with the 3-speed settings.

The 2-speed setting trigger gives high torque at setting no 1. Setting no 2 is used for high speed. Now, to attain maximum torque you have to understand the numbers and symbols on the drill and what do they mean?

The numbers are designed with a rotational clutch. This clutch rotates and helps you adjust the drill torque on your cordless drill. There is also the adjustable mode system that comes with 3 gears. These gears are represented with 3 symbols which are:. Thus, this whole intelligent system of numbers and symbols is known as drill torque setting. By adjusting these settings you can adjust the torque according to your work or the material. The best cordless drill with high torque stays with you as a trusty right-hand man to help you overcome different ordeals.

Perfect in the market. Every manufacturer has to select and choose certain aspects that precede others while they lack in some in which other brands exceed.

I had to go through a great ordeal just to get all those best high torque drills. Searching through these buddies and putting them on this cordless drill torque chart took a phenomenal time. Perfect all good anywhere.

They are machines and they have their set of problems and limitations as well. The other factor is that no one I found actually publishes the Constant K figure, which I had to work backward to find from a manual that offered me total watts, max torque output as Newton Meters, and the corresponding no-load max speeds. Combining this together, and using this as anything other than the roughest of estimates would be misleading. I originally wrote this article back in In , Stuart over at ToolGuyd who holds a Ph.

UWO is simply a value for which no useful cross-brand torque specs can be extracted. Well, yes… and no. If you are trying to find what drill has more overall power, Unit Watts Out is a great way to compare. However, two drills can have the same Unit Watts Out rating, but one has higher torque on the low-speed setting. It is a combination of the two that gets results.

Unit Watts Out is measured by a machine that takes into account how much speed the chuck has along with the amount of resistance which requires torque and has several different settings and tells the engineer the maximum that it produced.

This most likely occurs in mode 2 on a three-speed drill. If you need the maximum possible torque for an application, then you need to know the max torque outputs for the drills you are considering. Ideally, knowing the Unit Watts Out and how it is translated as the max torque would be a measure that combines both into a truly useful set of numbers.

It would be great to set up a shootout and know the overall power ratings before I even started testing. It would be great if all of them would put one more line to their spec sheet. Most would need to include that Unit Watts Out value. DeWalt and Porter-Cable would simply need to publish torque ratings again. Then, you and I could decide based on which measurement of power was most applicable to us. One last note about the equations I gave you. Please understand that they are virtually irrelevant.

Statistically, there is too much error there to account for. It will change from tool to tool. On the clock, Kenny dives deep to discover the practical limits and comparative differences for all kinds of tools. Off the clock, his faith and love for his family are his top priorities, and you'll typically find him in the kitchen, on his bike he's an Ironman , or taking folks out for a day of fishing on Tampa Bay.

The battery-powered blower landscape sure has changed since we did our first head-to-head review several years ago. There are a lot more options and the performance is leaps and bounds ahead. So who makes the best cordless leaf blower in ? When you need to grip, position, twist, cut, tighten or loosen various things, pliers can cover a pretty broad range of applications.

Their general design consists of two handles, a pivot, and a head. Consequently, […]. We pulled together some of our favorite tools and gear this year to give you some options for the best tool gifts for Christmas ! Gear and Tool Gifts for Dad […]. How much range?

How quiet? How much weight capacity? These values are a way to quickly filter out the better-suiting options from a pool of too many choices. If they offer a satisfaction policy then I have no problem taking advantage of it. Sites like yours definitely help to narrow down the choices to the ones I actually buy and try out. I stand by my comment as I can assure you from actual use that one particular brands 12v drill that claims 30nm is less powerful in real use than another brands version that claims the same torque.

And this is having used them back to back. I personally treat torque specs as a way to generally characterize a drill. Is it a compact drill? Heavy duty? If the speeds are wildly different, that could be a red flag. The first would have some speed sacrificed for higher torque, which to me would suggest a lower performance motor overall.

A great article but still all confusion. Publishing an actual torque curve, or even just a point along the curve, such as torque when loaded down to half the rated RPM, would also be more useful. Wow I asked if there was a way and you delivered a math equation that took me back to college. Nice write up but way too involved for joe public to convert and then compare Surely a DeWalt marketing scam.

None of any of that matters. I admire the work that took to research and write, but all I care about is which drill will bore the fastest, largest, deepest hole, or which impact will set the largest lag in hard wood.

In my personal experience… I think SBD stopped caring about comparing specs with other brands, and put together a more honest spec on their tools just to avoid lawsuits. Think about it. Is a spec on a box a guarantee that, in all the steps the machines took to manufacture that product, the end product is guaranteed to perform as if it is in the lab at all times? Reality says no.

We, as people who live in Reality, and are not stupid, would therefore never hold a company to those specs in real world conditions anyways. So… Why print them at all? And in THESE cases, I believe the modern tendency for litigation against companies for false advertizing becomes an annoyance that none of these manufacturers want to be bothered with. What if SBD got too big to bother with this? And, ultimately, just pays attention to what the SBD brands compare to themselves?

Everything that they print and advertise as specs is designed for the one purpose and that is to lure you into buying their products. This is why they print inch lbs and not foot lbs on the packaging along with rpm, ipm, and so on and so on.

None of which has anything to do with what matters to the intended use of the tool. In reality Inch lbs are very seldom used to spec a fastener. Everything is done in foot lbs. Set the wrench to the correct foot lb value and squeeze the trigger.

You may have to adjust it several times in order to dial in the exact amount. But in reality ft lbs is the number that counts. Impact wrenches often have ft-lbs specs. Inch-pounds instead of ft-lbs? You need a hard-joint coupler and a properly calibrated torque meter, and you take the measurement as RPMs approach zero. But the units? One dozen, twelve, same thing.

Is it wrong to market a package of 12 bagels vs. Both engineering and sales went down, way down. All because the sales person sold the owner a bag of cow chips. A simple graph showing power and torque at different speeds would make comparison easy and accurate.

Read that again. At what RPM was the measured with. So you know — there is a standard testing model — use for engines for decades. These motors motor gearbox assemblies — whatever are run on a dynamometer anyway. So post up the chart.

OH nobody wants to see that. Golly I bet many of you did when you bought your last vehicle right? Circular saws — golly what torque does it make when running at RPM? It cuts it though, mostly. Impact drivers — X inch lbs. ANd Z impacts per minute. Does it really apply inch lbs on a bolt — in wood. Some of the best testing — as is done on this site too — is practical example. Both using their respective compact batteries.

Because the Hitachi Cocao put in 16 more holes in the test because the motor was that much more efficient. Then it might be other features you need in a drill — like you can carry it without a support crane. It comes in pink, who knows. I mean I could use the hell out of that.

Anyway — great read. Just like in audio systems while standardized a bit. Or you know pick whatever market. Thank you Stuart for the great article. Yellow, red, blue, green, or pink have almost no bearing on how well you us it. I live across the street from an flour mill all built with hand tools and craftsmanship. Logic be damned. Sorry, but this is just more marketing BS, trying to look legit to the eyes of customers but at the same time making it impossible to compare across brands.

It might as well be a label saying good, better, best or a color coded label, etc. Just ask the Dewalt engineers what they look for when they shop for motors: the answer will most likely be a torque- speed graph. This how any decent motor is specified, whether electric or gas. Tool companies can easily produce a graph for each tool model they produce and it would make it easy to compare across brands — perhaps so easy that it will reveal the BS too much.

One other note, it is a bit irritating to see torque specified in in-lbs or ft-lb. I know it is a colloquial expression, but it is really lb-ft. The other way is a unit for moments. The only way I would trust UWO would be measured at the chuck.

Similar to a car, which you measure real HP or watts at the rear wheels, not at the crankshaft. I think Dewalt are trying to make the point the max torque is not a reliable indicator of real world performance.

I think that the choice of tool is much more complicated than we are giving Stuart credit for here. We are influenced by price, brand, battery system, previous experience with stores or manufacturers, friends, colleagues, co-workers, adverts, the press, internet blogs, and many more. Even if we do get specific about something — we decide we need a tool that weighs less than X, or is more powerful than Y, or shorter than Z — we can still make a short list of tools that meets the needs, and then we choose based on all the other more subjective things.

You see fundamentally, human beings are not rational. No-one has ever actually needed a sports car, for example. Yet I have one. Cars are a good example. People have mentioned how cars often are specced with torque curves. So many other things influence us. Which is the tool we will get the most satisfaction out of using? So is UWO or power a better discriminator?

Probably each is better is some situations. But this is at the root of why what Stuart does here is so valuable. Choosing the right tool is hard. Personally, I do use the specs to choose cordless tools, but like this. I am bought into M12 and M I have one DeWalt 8V max tool. Typically, I will look only at tools on one of these platforms. And that works well enough. So the specs do help. A while ago, I did jump platforms.

I had a range of perfectly good yellow tools, and a set of old, broken NiCd batteries remember them? Then, the reviews were vital. It was really important that I chose the right platform for me. I chose red. Since then, choosing the next tool has been relatively easy, and specs have mattered. But torque is just as good for me as UWO would have been. My final thought is that there really is no perfect answer.

Example — my most powerful drill is a country mile ahead of any of my others. But I hate it viscerally. It is cheap junk and I begrudge every one of the pennies I spent on it.
