What To Look For in a Concrete Breakers
For most domestic jobs, a mains-powered concrete breaker will be all that’s required. Look for a machine with over 1000 W of power.
From our research, we’ve found that a 1000 W concrete breaker will generally break through concrete up to 15 cm thick. For a more powerful model, choose a 1500 W concrete breaker. This should get through concrete of at least 20 cm.
A petrol-powered concrete breaker can easily break up concrete at least three times this thickness, but is unlikely to be necessary for most jobs around the home. Also, if you’re new to these kinds of power tools, it’s advisable to go for a manageable electric model. Petrol models are very powerful, but potentially unwieldy. They’re extremely efficient as they quickly slice through concrete.
Choose a concrete breaker that weighs around 10 kg if you have concerns about controlling a bigger machine. It may take longer, but will feel safer. If you’re comfortable using power tools, breakers that weigh around 20 kg will use their own weight to dig into the concrete.
Also, for versatility and value for money, look for concrete breakers that come with a variety of chisels. Flat chisels give good control whilst breaking off concrete and brick. Pointed chisels are better for chipping. The best concrete breakers will come with at least a flat and pointed chisel to help complete most jobs.
Additional features to look out for include a secondary handle that’s easy to adjust, and a carry case to keep all of the components securely together.
Overall, I’ve recommended the Einhell 4139087 Demolition Hammer TC-DH 43 as my top choice. Offering 1600 W of power, yet weighing 14.6 kg, it strikes a good balance between strength and manageability. It comes with two chisels, which are easy to change over, and will break through concrete up to 20 cm thick.
