Some people say you don’t bring a bread knife to a knife fight; in the case of chipping or drilling jobs, you don’t bring a carpenter’s hammer to break through concrete – you bring a rotary hammer. A rotary hammer, like the models we’re reviewing today, allows a contractor to break through tough concrete as if they’re made of butter.
Of course, this implies the rotary hammers from Milwaukee and DeWalt are those bulky and heavier units we regularly see in construction sites. Both of the units we have today have been engineered to be compact and light without weakening their power.
DeWalt’s long pioneering streak that started in the rotary saw continues in the DCH133B. The mark of Milwaukee Electric Tools, on the other hand, cannot be denied in the 2715-20 M18 since it shows off the company’s design advantage in making lightweight power tools.
We’ll review both tools in terms of performance, user-friendliness, battery life, and value for money. Let’s get this battle going.
Both rotary hammers in this review provide good value for your investment and will help the user remove tiles or bust up concrete fast. There are a few slight differences that uniquely position each product for use by certain slices of the market for rotary hammers.
The DeWalt DCH133B is perfect for contractors who are tired of hauling more than 100 lbs of equipment from job site to job site since this rotary is both compact and light. It will allow users to perform overhead drilling since it’s relatively to hoist this rotary hammer to get at those spots in higher positions.
For home users who want to work on smaller projects and prefer quiet machines to do the job, the Milwaukee 2715-20 M18 reduces both noise and vibration for a more focused and relaxed work session.
DeWalt DCH133B Vs Milwaukee 2715-20 M18: Which Is The Better
Integrated electronics in the drill optimize the tool’s performance for consistent speed regardless of bit size. There’s no bogging down even if you outfit this with the bigger size drill bits.
Great Speed of Application
The DeWalt DCH133B provides 2.6 joules of impact energy on concrete surfaces. This performance parallels the power of heavy drill hammers without their heft and weight.
DeWalt modeled the DCH133B with German engineering in mind. The manufacturer outfitted the machine with a brushless motor for increased power to do its job.
The DeWalt DCH133B rests at 5.75 lbs – extremely light for a rotary hammer. Its compact form also allows contractors to use it narrow or confined spaces like niches.
What We Like
- Cordless for better access to areas far from electrical outlets and for a hassle-free and snag-free experience.
- The DCH133B works up to a mean 5,500 Blows Per Minute that reduces anything you set it to rubble.
- Three configuration settings allow you to set the tool to work as a drill or a hammer drill, and to hammer/chip at surfaces.
What We Don’t Like
- Once the battery runs hot, the tool may drain batteries fast.
Users can go for batteries around 6.0 AH for more runtime or plug into an outlet for continuous power.
Power and Performance
The drill provides ample performance and will reduce concrete and stone to powder thanks to the power from its brushless motor. This Milwaukee drill puts out 3.3 lbs of impact energy while revving up from 0 to 1,350 RPMs or 0 to 5,000 BPMs.
Long Life Per Charge
The battery pack for the 2715-20 M18 boasts of Milwaukee’s Redlithium technology that adds up to 20% more energy and 2x more amount of re-charges than the lithium-ion batteries found in the market. Users can work the rotary hammer as close to 8 hours if they need to bust through walls for the entire shift.
Milwaukee designed the 715-20 M18’s casing to mitigate the vibrations coming from the motor. Its hand/arm vibration reading rests at 8.6 m/s2. This results in a strain-free experience for users and prevents stress to their shoulders.
Users who want discretion on the speed and direction of application will find the 2715-20 M18 fits the bill. It allows users to set the drill to rotary hammer mode, to hammer only mode, and to rotation only mode.
What We Like
- Quiet performance that helps users concentrate on the project surface and avoid noise-related stress on the job.
- The tool allows users to work with a vacuum system.
- Frees customers from the limitations of cords while chipping or pulverizing concrete.
What We Don’t Like
- The tool may heat up quickly so users must pay attention.
Users can try and use the tool intermittently if it gets too hot. They should also make sure they wear gloves with heat protection to avoid burns.
DeWalt DCH133B Vs Milwaukee 2715-20 M18: Which Is The Better Rotary Hammer?
Although we like what the Milwaukee 2715-20 M18 puts on the table, we prefer the DeWalt DCH133B for its reliability and consistency when it comes to powering through brick, concrete, and granite. The DeWalt rotary hammer just churns out a noticeably more steady performance while on the worksite.
Both rotary drills stand toe to toe in terms of work time thanks to their lithium-ion technologies. What carries the DeWalt DCH133B further in terms of power and operational time boils down to its brushless motor as it provides 5,550 BPMs – 550 more than the Milwaukee cranks up to.
The Milwaukee drill hammer does come in a more compact form than the DeWalt DCH133B but it also comes short in terms of cost savings. Milwaukee has priced its product around 2x more than the DeWalt DCH133B.
The DeWalt DCH133B performs better and is more competitively priced. This makes its offer very hard to refuse compared to its rival from Milwaukee.
Despite our favorable reviews for the DeWalt rotary hammer in this round, we’d like you to know that the Milwaukee 2715-20 M18 is also a superior product in its own right. It’s very user-friendly and performs well for projects that require a light touch.
For more serious uses, however, you should be packing a DeWalt DCH133B in your kit before you wheel off to your project site. Choose and invest in the right rotary hammer according to your needs.
