Milwaukee 2704-20 M18: Cordless Hammer Drill With An Industrial Strength Punch

Milwaukee 2704 0 M18

No matter whether you’re a professional tradesman or weekend DIY warrior, there is one tool that you simply cannot be without. And that is a powerful drill and driver combo. Yes, you can get kits that have these as two separate tools.

But how many times have you been mainly drilling holes and you just want to quickly switch to a driver bit to fix a screw. With a combo tool that is so much easier to achieve. But finding a high performance hammer drill with decent torque for heavy duty driving is a more difficult task than you might think.

But that’s a gap in the market that Milwaukee have filled with an exceptionally well built tool. The M18 is one of those tools that once you have used it once, you’ll be wondering how you’ve coped without it.

It really packs some outstanding features that will be right at home on a busy job site or in your DIY kit. On this page you’ll find out exactly what makes it so great and how you will benefit in many different ways from this great investment.

Quick Overview

When it comes to power tools, Milwaukee is one of those names you’re just going to see everywhere. You won’t find a construction site in America that doesn’t have some trades people using their equipment. This is due to a reputation that has been built up over many decades. And the result is quality workmanship and very reasonable prices.

The same is the case with this M18 hammer drill driver combo. The built in brushless motor is designed to last a very long time, even when used all day every day. The great thing about these motors is that they generate less heat and use far less power. So, you also end up changing batteries a lot less frequently.

From a power output point of view you’ll find some pretty impressive numbers. The hammer drill will spin up to 2,000 RPM which makes small change out of even the toughest jobs. You won’t believe how fast you can get your work done.

And in the driver setting it will give you 1,200 pounds of torque which is more than enough for the majority of uses. Anything more than this and you’re heading for industrial grade equipment and prices.

To avoid any overloading of the clutch and motor, there is an intelligent monitoring system in place. This will automatically reduce output if the pressure and/or temperature rises too much or too suddenly. This helps to reduce breakdowns and will make it last an awful lot longer.

What’s amazing is that the company have managed to pack this power into a very small and compact device. The result is light weight and you won’t feel fatigue in your hands and arms when using it for a long time.

There are just a few minor complaints that you might find. First of all, the chuck could be a bit more robust, as under intense pressure the bits can come loose after a while. Also, excessive vibrations in hammer drill mode can cause the side handle to move slightly, so make sure you regularly adjust and tighten it.

If you plan to use it a lot for driving screws and bolts, then just be aware that there are no gears, so you cannot switch between different speed settings. Not the end of the world, but not ideal for high precision work.

Detailed Analysis

As you can see above there are some excellent features built-in that will really help you get through your work faster and more effectively. There are a few items that we want to highlight a bit more, so that you can really get a better picture of why this is such a good tool.


As already mentioned, this tool houses a brushless motor which is a huge advantage. These types of motors are more complex and have a lot more monitoring and timing equipment than the standard brushed type. We won’t go into too much detail, but basically these types have far better timing mechanisms that reduce energy use and friction.

As a result you will change batteries up to 30% less often and the motor is less likely to break down from overheating and overload. If you’re going to be using the tool on a regular basis, then brushless is the only sane decision to make.

Clutch And Gears

With the amount of torque being generated, it is no surprise that the clutch is of excellent quality. There is very little give in the head when the motor is not turning, which indicates that there is a tight grip in place. This also reduces the impact on the clutch when the motor does engage, especially in driver mode.

As for gears, well basically there aren’t any. This is a bit of a letdown, but if you really do not precision speed settings for driving, then a combo tool like this is not going to be the best choice anyway. Gears basically work to limit the effect of the trigger on the speed. In lower gears you might only spin up to 500 RPM, while higher speeds spin up much faster.


First of all we have to mention that this particular model is the tool only package. That means you don’t get any extras like battery and charger. This does keep the price down, but if you don’t have other M18 compatible Milwaukee tools then you’ll also need to invest in batteries and chargers.

The great thing is that the batteries from other M18 tools are interchangeable. So you won’t need to have multiple sets of batteries to keep charged and constantly figure out which one belongs where. We would highly suggest that you always have 2 batteries if you’re planning to use it for hours at a time. This is the only way to reduce downtime.

Main Benefits And Advantages

In this section we want to highlight what our research has revealed to be the main benefits. Talking just about the different tech specs is informative, but let’s face it, you’re really only interested in how it will make your life easier.

Battery Life

This is one aspect where pretty much all Milwaukee tools shine. The Lithium-Ion batteries they produce are of excellent quality. But your main concern will be how long do they last. This is mainly dictated by how the tool draws down the energy.

In this case, the combination of brushless motor and system monitoring for overload, it really minimizes how much energy is drawn on a constant basis. Compared to cheaper and less technically advanced devices you will easily see a 30 to 40% longer usage time per battery. And that means less downtime and a more effective workday.

Powerful Speeds

When you’re facing into big projects at home or on a jobsite, then you want to make sure you get through it with precision and speed. When it comes to drilling, there are only two ways you can speed up the process.

First, you have to have high quality drill bits that stay sharp and don’t wear too quickly. This is a must have, as your drill will be ineffective with cheap bits. Secondly, you need high RPM. The faster the drill can spin the quicker you’ll get through the work. And this can have a significant impact on your productivity and profitability.

The good news is that you can boost that productivity with 2,000 RPM that comes with this great hammer drill.

Powerful Torque

Unlike drilling, when you need to drive screws or bolts you’re not so focused on RPM. Here it is much more important to focus on the torque that can be generated This is essentially the twisting power that can be generated. And for driving screws and bolts in to heavy-duty materials, like hardwoods and steel, you really need a lot of power.

You simply cannot afford to stop each time and use a manual wrench, because your tool is not up to the task. For the majority of situations, the 1,200 pounds of torque on this Milwaukee 2704 will be more than enough.

Suitable Uses

The great thing about this power tool is that it’s basically suitable for everything from home DIY to professional construction and repairs. In this section will highlight some professions who will find this particularly suitable.


For professional plumbers the appeal is likely the powerful torque in driver mode. Whether it’s residential or commercial plumbing you are fitting or fixing, you will want to have a tool that will tighten even heavy bolts and very long screws. And the fact that the battery will last longer than the majority of other options means you have a lot less downtime.


For electricians it’s going to be a mix of the drill and driver functionality that is appealing. But if you have smaller screws and devices to work on, then the lack of gears may be a problem. It certainly would be a problem if you really need to get into a slower mode to avoid overtightening smaller screws.


The big appeal is going to be the high speed drill. At 2000 RPM you’ll be able to get through even the biggest commercial jobs. If you regularly face into an entire day of drilling and fitting timber beams and trusses then you want to be able know that you can do so quickly and reliably. Just make sure you also invest in a good set up bits as you can quickly get slowed down if drill bits start getting blunt quickly.

HVAC Maintenance

For HVAC repairs you probably won’t find a better combo tool. Because you get so much torque you won’t struggle to work heavy bolts and screws or get old rusted one out with ease. And because you’ll regularly work in tight spaces, the small and compact size will be ideal. The ability to drill into heavy masonry and concrete at high speed will also make tougher jobs a lot easier for you.

Gain Some Additional Convenience

We already mentioned that this product model is the tool only option which is great if you have M18 batteries and chargers already in your tool bag. But if this is going to be your first Milwaukee tol, then there are a few things you’ll need to invest in.

First of all, you should always have two batteries to be able to switch out and not end up idle. The M18 batteries do charge fast, but it still takes long enough to slow you down significantly. You should also get one of the fast charger units, as it will make sure that you have enough power at all times.

Finally, don’t spend big on a drill only to scrimp on the drill bits. A drill is only going to work well if you have drill bits that are advanced enough to stay sharp for a long time and don’t break on the slightest bit of pressure.


At this stage you’ll have all the product detail to decide whether the Milwaukee 2704 will be a suitable option for the jobs you do. It’s a high performing professional grade tool that will stand up to the demands of a busy job and construction site. The high price is certainly justified when you consider how much longer it will run on each charge. Just click on the price check buttons above to get the latest deals at Amazon.
