It is no secret that Milwaukee offers a wide range of power tools that go well with your tasks – may it be light DIY projects or heavy maintenance works.

The Milwaukee Electric Tool is an American company that began operating in 1924.

With user productivity at the core of everything, the people behind Milwaukee have developed the M12 and M18 Cordless Systems, where inefficient manual tools are redesigned into advanced workhorses powered by their own battery technology.

However, with the growing number of Milwaukee tools, it’s also getting a lot more challenging for users to pick which one they have to use.

For that reason, this article aims to help you decide on which Milwaukee cordless impact drill to go for.

Milwaukee M12 2404-20 Vs M18 2801-20 Review

Size and Weight

When choosing an impact drill, most users take a look at the product’s size and weight. It is important to have a tool that is easy and comfortable to use even for an extended period.

As the company ages, Milwaukee has never failed to produce compact and lightweight impact drills such as Milwaukee 2404-20 and 2801-20.

Milwaukee 2404-20 and 2801-20 are both lightweight at 2.8 lbs and 2.5 lbs, respectively. This only shows that both tools can be handled by anyone for any task with less fatigue.

Winner: Both

Motor Type

Milwaukee 2404-20 and 2801-20 have been equipped with brushless motors, and compared to brushed motors, they are more efficient to use.

It is because unlike most brushed motors that are made of carbon, brushless motors use magnets to generate more power with less heat. And with lesser wear on all parts, brushless motors also prolong tool service life.

Winner: Both

Battery System

Almost everyone would agree to the fact that battery life greatly affects their overall productivity. To do more work, one needs to have a tool that can last until their task is completed.

So, to address this matter, Milwaukee has restructured its battery systems along with their systems of cordless tools.

Milwaukee 2404-20 uses the M12TM battery system, powered with a 12V Lithium-ion cell. Milwaukee 2801-20, on the other hand, uses the latest M18TM battery system, equipped with an 18V Lithium-ion cell.

Evidently, with Milwaukee 2801-20, you can be more productive on your DIY tasks or maintenance works.

Winner: Milwaukee 2801-20


Milwaukee aims to craft power tools that do not just deliver results but also can withstand harsh situations.

Both Milwaukee 2404-20 and 2801-20 come with a REDLINKTM Intelligence technology that protects the tools against abusive applications. This technology is also capable of monitoring the tool temperature to prevent damage and maintain battery health.

However, Milwaukee 2801-20 is further housed in an all-metal gear case, which makes it more durable than the Milwaukee 2404-20.

Winner: Milwaukee 2801-20

Torque And Speed

Even though these are lightweight power tools, it doesn’t affect how they can deliver high output in drilling/driving jobs. And most users would go for the impact drill which possesses higher torque and speed values.

Milwaukee 2404-20 can deliver a peak torque of 350 in-lbs while getting most drilling/driving tasks done at a speed scope of 0 – 450 RPM or 0 – 1,700 RPM.

Milwaukee 2801-20, on the other hand, can perform a maximum torque of 500 in-lbs while drilling through soft and hard surfaces at a speed scope of 0 – 500 RPM or 0 – 1,800 RPM.

Both Milwaukee cordless impact drills prove that they can power through any surface, but without question, Milwaukee 2801-20 does better in granting its users a higher output towards their tasks.

Winner: Milwaukee 2801-20

Other Features

It is undeniable that Milwaukee has a line of production that focuses on user productivity and ergonomics.

Milwaukee 2404-20’s handle is remodeled to a pistol type and it is textured as well to make it easier and more comfortable to use. It is also furnished with an LED light positioned perfectly below the clutch to illuminate the driving/drilling spot.

Milwaukee 2801-20 has a micro-textured grip which makes it easy to handle for prolonged use. Just like Milwaukee 2404-20, it also has a bright LED light placed below its clutch to focus on your poorly-lit drilling spot. It also comes with a belt clip so you can conveniently hang it anywhere when not in use.
