Milwaukee 2704-20 Hammer Drill/Driver – The Basics

The lightweight and compact design of this hammer drill will be appreciated by all those who deal with heavy-duty projects on a daily basis. The model’s auxiliary handle makes it very easy to exert the necessary amount of force when dealing with more challenging tasks.

The unit’s brushless motor works like a charm, reaching the top speed of 2,000 RPM and having the peak torque of 1,200 in-lbs. Once we combine this with the integrated REDLINK Intelligence system, we get a performance that is bound to impress both the hobbyists and professional contractors.

Just like we expected, 2704-20 features variable speed settings and comes with a convenient belt clip holder. It is covered by Milwaukee’s 5-year warranty (one of the most generous on the market) and is powered by high-performance REDLITHIUM battery packs, which are interchangeable between all M18 FUEL tools.

The Features

The Design

The Milwaukee 2704-20 is quite small, with the dimensions of 13″ x 3″ x 12″ and the weight of just 3.5 pounds. This is quite light in relation to the amount of power that this hammer drill offers. Once the battery pack is attached to it, the drill feels well-balanced in hand, and it doesn’t feel overly heavy or too light.

As a cordless model, the 2704-20 makes it very easy to work in areas that are far from the nearest power source. It’s something that will allow you to move from one project to another without having to worry about the length of your cord.

The model’s design takes the user comfort into consideration, especially when it comes to long working hours. The included auxiliary handle provides excellent control over the device and has a rubberized surface which prevents slippage. It is also shorter than on most other hammer drills, which makes handling this device less awkward during high-torque applications.

Another great feature is the presence of a belt clip holder, which lets the user keep the device with him as he moves around the job site.


As it runs on brushless motor technology, 2704-20 is a very efficient hammer drill. As you probably already know, brushless engines are typically more expensive to make than the brushed ones, as they guarantee a longer tool lifespan and provide better performance. Furthermore, they require far less maintenance than their brushed counterparts.

With the peak torque of 1,200 in-lbs and the maximum of 32,000 blows per minute, the model is more than capable of completing every task you throw at it. Depending on the nature of your project, you’ll be able to choose between two different speed settings -0-550 RPM and 0-2,000 RPM.

Due to the presence of variable clutch settings, the user can also control how much torque he wants to use for a specific project. Being able to adjust the amount of torque to the task at hand prevents the risk of ruining your materials and saves energy.


Just like all other Milwaukee M18 FUEL tools, this one is also powered by the REDLITHIUM 18V batteries. These batteries are among the best on the market, as they have a long lifespan and provide more work per charge than the competition. If you decide to purchase 2704-20 in its bare-tool version, don’t forget that you’ll have to buy the batteries and the charger separately

Things we liked about it

It’s pretty hard not to love the design of this cordless hammer drill. Besides the compact dimensions and low weight, the model also has a convenient auxiliary handle with a rubberized surface. The belt clip, on the other hand, allows easy carrying of the device around the job site.

The unit’s performance is also impressive – it goes through concrete like a knife through butter. This is made possible by the combination of a potent brushless motor and Milwaukee’s REDLINK Intelligence system. Finally, five years of warranty inspires confidence in the durability of the tool and shows that Milwaukee actually cares about its customers.


Things we didn’t like

Unfortunately, this model lacks a couple of additional features that are usually present on M18 devices -the battery fuel gauge and the LED headlight. Furthermore, some users reported that the chuck on their device doesn’t hold the bit too well, although we didn’t encounter this issue.

General User Impressions

The user opinions on this hammer drill are overwhelmingly positive. People who bought 2704-20 agree that it possesses a remarkable amount of power and enough torque to go through concrete, mortar, and stone. They also praise the overall ease of use and the selectable levels of torque force.


The Milwaukee 2704-20 is a fantastic hammer drill/driver, as it is compact yet powerful and also very user-friendly. Although it lacks some features found on its 2704-22 cousin, it’s still a pretty good bang for the buck and will undoubtedly assist you in accomplishing every project with ease.
