What Is It
In order to create, you have to destroy something first. This saying can be applied to a lot of situations but totally true to 99% of construction works. The demolition hammer is probably the best tool for crushing concrete, brick, and other stubborn material. You can easily use it for chipping the tiles away, making large holes in the walls, and plain simple building demolition. In other terms, it's a more powerful version of a hammer drill, save for the torque element that is not featured here in most cases.
Similar to many other power tools, demo hammers can be driven with hydraulic or air pressure force from a compressor or with an electric motor. Still, the basic conception is the same everywhere: the chiseling bit moves back and forth at an immense frequency, allowing the chisel to dig into the cement, bricks, tiles or other stuff and chisel them off or break into pieces. That way, you can remove old driveways, pavement roads, brick fences, tiles on the walls or the whole buildings altogether by crushing them into smaller, easily disposable parts.
It's worth mentioning that demolition hammers move the chisels at the high speed, so they also produce a considerable amount of vibration, noise, and send a lot of dust from the crushed materials into the air. Therefore, we strongly suggest getting some hearing protectors, safety eyeglasses, and thick anti-vibration gloves to reduce the arm strain. As for the additional construction equipment, check out our recent reviews of the best concrete mixers to prepare the mortar, laser levels to even bricks, walls or flooring out, and hammer drills for when you have to drill smaller, more accurate holes than it's possible with a demo hammer.
A Bit of Everything
When it comes down to the best power tools reviews, you can be certain that most of them will feature a Bosch product in the list. As you can see, this one is no exception at all. This is no wonder because this Bosch demolition hammer is designed for some heavy work. It boasts 14 A motor that delivers up to 1890 BPM. This is enough to effectively crush the toughest concrete into a dust powder. There's also a speed switch with 6 modes for various tasks. Also, it works with SDS-max bits that can be switched without additional tools and are available in most of the hardware stores.
In such devices, the ease of use is one of the main concerns just the same as the performance characteristics. And here this Bosch 11316EVS model pulls ahead of its competitors. The soft-padded rear D-handle dampens a considerable amount of vibration. The auxiliary handle can be rotated at 360° around the shaft, providing steadier and more accurate control of the bit and the hammer body. What we really liked is that both handles are conveniently padded for user's comfort. However, don't forget about the safety measures like vibration gloves, helmet, and eye protection. Anyway, this Bosch demo hammer also features a 12-position Vario-Lock for changing the bit position that is especially handy when you have to groove a concrete wall in different directions to install an electrical wiring. What's more, the Constant Response™ feature provides a smooth start and protects the motor from the overloads. At 22 lbs weight and relatively small body size, the Bosch 11316EVS SDS-Max Demolition Hammer is a superb multi-functional power tool that can be equally recommended to professional demo crews, construction workers, and even to untrained users as well.
Light as a Makita HM0870C Demolition Hammer!
Surely, the Makita HM0870C is one of the most compact and lightweight demolition hammers on the market with its 11 lbs body weight without a bit attached. However, the small size is not a disadvantage here. Although it features only 10 A motor, the performance characteristics are very satisfying. The lack of impact power is fully compensated with its speed. At up to 2650 BPM rate, it punches the stubborn surface so fast that it may crack just as fast, as under the onslaught of its more powerful counterparts. The speed regulating switch offers a range from 1100 to 2650 BPM. The chuck is compatible with all SDS-max bits. Keep in mind, that there's no torque here - the bit moves back and forth at an immense speed, hammering down almost any concrete or brick obstacle in its wake. Unlike many other models, the Makita HM0870C can inform its user about a malfunction or when the carbon brushes have around 8 hours before they are totally worn out and require a change. We want to take a moment and praise the company for adding the bits grease inside the hard plastic case in which the tool is shipped. Traditionally, the heavy-duty power tools like this one require more maintenance than corded power drills or electric screwdrivers, thus, we welcome such attention to the customers. Also, the hammer comes with an auxiliary 360°-rotatable handle that provides a steady grip of the tool while you are trying to push the bit deep into the bricks or concrete. Overall, the Makita HM0870C Demolition Hammer would be an optimal solution for small construction sets and demolition works. It also works exceptionally well at grooving the concrete walls and floors for the small tubes or wiring.
XtremepowerUS Heavy Duty Electric Demolition Hammer
Powerful and Efficient
With the XtremepowerUS 2200Watt Demolition Hammer is a really fine jackhammer for crushing stuff like bricks, concrete slabs, granite tiles, and so on. For the relatively small price, you are getting the electric hammer, a couple of chisels, a hard storing case, and a pair of gloves. The cost didn't affect the performance, though. This XtremepowerUS breaker boasts a powerful, single-speed operated 20 A motor that delivers up to 1900 BPM with incredible 55 J. Obviously, such tool can't be too lightweight. However, the weight load from above helps the chisel dig into the concrete with more brutal force. Speaking of the bits, it's compatible with any 1-1/8" hex shank chisels.
In addition to the standard D-handle, the demolition hammer has an auxiliary 360°-rotatable handle. The motor requires almost no maintenance, just check out the oil level and refill it when it's low. Also, never forget that the chisel has to be greased as well to perform smoothly. Overall, the XtremepowerUS Electric Demolition Hammer is a brilliant choice if you need an electric breaker for some home remodeling. Although this demo hammer might not break the stones, it might surprise you with how easily it can crush the old concrete pavement or a brick wall.
In Clouds of Dust
The DeWalt D25899K jackhammer features a remarkable 14 A motor that can deliver up to staggering 2040 BPM. With such power, it's capable of crushing concrete, stones, bricks, asphalt or any other hard and stubborn materials with similar structure. The classic yellow-black DeWalt plastic body has a soft rubber rear D-handle that can be held with two hands at once. As for the auxiliary handle, it can be folded up, so it doesn't have to be taken off when you put the hammer inside the storing case (included). The keyless chuck supports only SDS-Max chisel bits and can be set in one of the 12 available positions. Thanks to this, you won't have to hold the hammer at an awkward angle with your hands when you perform a precise chiseling. What's more, the rear handle has a special spring design inside that reduces the recoil from the hammer. Still, we highly recommend buying a pair of vibration-dampening gloves, over-ear headphones, and eye protection. When you crush the concrete, the clouds of hazardous dust are inevitable, unless you lay it down with spraying water. Still, in a lot of situations, using water is simply impossible. Therefore, we liked that this D25899K has spring-loaded seals that prevent the dust from getting into the motor. Overall, the DeWalt products are a popular solution with many positive responses from different construction and demolition workers. Thus, this DEWALT D25899K SDS Max Demo Hammer is a safe choice for any kind of job. Also, it's backed by 3-year US warranty.
TR Industrial TR89105
For Basic Heavy Works
The TR Industrial TR89105 can lend you its relentless strength for demolishing walls or digging the trenches so that you would save yours for other tasks. This hammer comes with almost everything you might need for effective demo work. Along with the device, you are getting an oil container, 1 hex-pointed, 1 flat chisel, safety glasses, one pair of thick gloves, and a fine plastic case for storing them all in. The "On" button is placed from the inner side of the D-handle. We want to note that it can be too narrow for some people to hold with two hands at once. Especially, wearing thick gloves. Therefore, place the second hand on the auxiliary handle that can be conveniently rotated around the hammer.
Its 11 A motor here can deliver up to 1800 BPM. With the right bit, you can reduce to dust any concrete and bricks surprisingly easy. Speaking of the bits, the chuck is designed for 1.2" hex shanks and holds them with a simple spring clamp. Thus, changing the bits can be done in less than 30 seconds. Concluding, the TR Industrial TR89105 Original Demolition Jack Hammer is designed for the heavy duty and copes with most stubborn materials. Considering the price, it's a viable solution for the home owners who require an electric demolition hammer to renovate their lawn or parts of their houses.
