If &#;get through concrete&#; means - i want to break up a patio :My 2 cents - if youre wanting to demo a concrete patio - you are not doing that with a rotary hammer.. get a small sds plus rotary hammer like a Bosch bulldog or the equivalent Milwaukee for your other projects. If you buy used or off brand, just make sure it has a rotation lock out feature to use chisel bits. I have an old Hiliti that does NOT have that. If youre renovating a house - either invest in a cordless line if you have the money to do so, or if you are conserving money for now - just get corded.. SDS PLUS - not SDS Max.. i dont see a Home owner needing to drill more than 1&#; holes. And in the rare case you have one, they make core bits in sds plus.To demo the patio - you have 2 options. Rent a commercial grade electric jackhammer if you think you need something full size (like 60lb ) and do all your breaking so you can return it.. OR - just buy a new smaller &#;Chinese&#; lighter duty breaker, like a 35 or 45lb for a lot less than probably think you think you can buy one for. I&#;m talking $100 to $150 SHIPPED right off amazon, with the bits and a case. . i have one.. i wouldnt open a demo business with it, but for projects at home - ABSOLUTELY.. the one i have has oil inside you can change to service - and I&#;d absolutely suggest doing that after the first couple hours.. just search electric jackhammer on amazon - youll find many choices - but most are likely all the same tool sold under different brands. You&#;ll find a ton of reviews with people impressed with these things.. for what youll likely pay for a 2 day rental, you can buy one and keep it - cause you never know. I&#;m betting you dont need a jackhammer enough to justify BUYING a brand named breaker, and if you decide you dont wanna keep the breaker - if you cant sell that $110 Chinese breaker for $60 - $75 when your done, something is wrong. If you have a patio and want an idea what your dealing with - after you buy your sds plus rotary hammer - drill a hole though the patio and see how thick it is..For reference - we use 45lb hydraulic breakers for the sidewalks we need to break to set poles. I&#;m sure they hit harder then a 45lb electric - but your patio is probably not very thick. If i had to guess I&#;d say the amazon option will do just fine. Start at a corner and work inwards. If you have a friend helping, have him move the debris over as it breaks off, hand him a shovel and undermine the dirt under the slab for stubborn pieces. You may need some cheap bolt cutters if there is wire set inside the concrete.I have a less powerful version of this one. While ive used it only a couple times for small things - but explore YouTube, read reviews on amazon. For the money how can you beat it? This is $106 shipped including the breaker bits.. its unreal you can find something like this so cheap that will do so much.F2C W Heavy Duty Electric Demolition Jack Hammer Concrete Breaker Power Tool Kit 2 Chisel 2 Punch Bit Set W/Case, Gloves https://www.amazon.com/dp/BW1M14/?tag=atomicindus08-20 You should be able to find a corded sds plus hammer drill (name brand) for under $200 new for the smaller jobs.My advice - do not buy a giant rotary hammer for &#;home use&#;. It will do neither project well. They are not breakers. They are chippers. You&#;ll spend $600 on a drill thats too big for what you need to drill, and for a chipper thats too small to break up a patio.. you need two different tools.Just for an idea - i think this is what i have - a watt version (one i linked is the newer i think), and here is what appears to be a not very mechanically inclined person using it on his patio. I&#;ll go out on a limb and say if your breaking a patio - its cause its not in the best of shape to begin with. Ive seen other videos of people doing bigger jobs as well.. but cmon - for $100??? And If you sell it for $60 afterwards - is this not worth the $45???? I&#;d just keep it though..To compare - a ONE DAY RENTAL of the small sized Makita electric breaker (about the same size as what I&#;m suggesting you just buy) is $78 for one day... the bigger one is $94 a day.. and the &#;pro&#; model electric is $113 a day..
When it comes to demolition, concrete breakers are critical pieces of equipment to get the job done. Concrete breakers have developed massively since its first design. Originally, breakers were oversized machines that had to be operated by a strong individual. However, since their first creation, concrete breakers have become far more manageable and safer. Nowadays a concrete breaker has more advanced anti-vibration systems built inside them. This allows users to be far more productive for longer periods without causing long-term damage such as HAVS.
In today&#;s market, there are many different concrete breakers to hire. Therefore, to ensure that you get the right tool for the job, we have put together this in-depth article to find the right match for your project.
There are several types of electric, petrol and hydraulic concrete breakers available on the market. These are better known as:
For light work such as removing render plaster and floor tiles, a power chisel is an ideal tool for the job. Power chisels are equipped with variable speed control, allowing you to undertake detailed work rather than a large demolition. These tools require electricity to operate their motor, which produces an internal pistol to pound, creating a hammering force.
A power tool that can perform heavy-duty tasks such as drilling and chiselling hard materials. Unlike SDS drills, rotary hammers have a hammer only function with no rotation. The pounding action created is caused by a piston driven by the crankshaft inside the equipment. Most of these drills are electrically powered, therefore you will require access to power to operate. Rotary hammers are multi purpose, allowing you to switch between drill or hammer only operations. These are ideal for concrete breaking depths of up to 40mm.
These larger hammers are designed to break through concrete up to depths of 125mm. Generally powered by electricity, but are ideal for both indoor and outdoor work. Similar to other hammer designs, the internal hammer is forced up and down within the tool by its motor. The hammer speed of a heavy-duty concrete breakers can be adjusted via a dial found on the machine&#;s body. Demolition hammers can weigh around 15kg, making them slightly less manoeuvrable than smaller concrete breakers.
The most powerful breakers are powered by either petrol or electricity depending on their design. Mostly used for breaking road surfaces, pathways, driveways up to 300mm in depth, these breakers are some of the largest handheld breakers available on the market. Heavy-duty breakers have a fixed output speed when in operation, which is a lot higher than others than smaller models. It is important to note that heavy-duty breakers weigh more than 30kg, making them harder to manoeuvre and operate.
Unlike other breakers, hydraulic breakers operate off an excavator or a fuel-powered generator for larger-scale projects. Hydraulic pistons exert pressure into the head of the breaker, generating the force to break through all types of dense rock. These types of breakers are used by the most skilled of operators on demolition sites.
Before choosing a breaker to hire, you need to make sure that you are aware of the following factors:
What is the thickness of concrete that you are breaking through? Not all concrete breakers are suitable to break through driveways and patios. Choosing the correct breaker can save you time, money and mechanical breakdown costs. If you are not too sure what size breaker you require, then always consult a professional.
Do you want the equipment to do more than remove concrete? Having a multi-purpose tool can save you from hiring an additional tools. Some concrete breakers also offer variable output speeds to tackle the toughest and most delicate of work.

Where is your project taking place? Do you require power for your breaker? Some breakers are petrol-powered, ideal for outdoor work. However, if you are working indoors, it is important to know if you have access to power to operate your concrete breaker.
Weight can be a big factor when it comes to choosing the right breaker. Breakers can vary from 5kg to more than 25kg depending on their output and power. If your project involves lifting your breaker to work through a wall, for example, you will want to choose one that you can handle safely.
Using a breaker that is too heavy to handle can cause injury to the user.
At this point, you should have a good idea of which concrete breaker would best suit you&#;re the work that you intend to undertake. During your search, you may come across lots of building jargon that may be hard to decrypt. So, to help you understand a bit more, here are the main things you should focus on:
Impact rate measures how many times the chisel hits the surface you are working on in a minute. This is measured in beats per mins (BPM) or revolutions per minute (RPM). The higher the BPM or RPM, the quicker your concrete breaker will work through the material. Even though you may choose a breaker with a higher RPM, it doesn&#;t mean it will break through denser materials.
The impact force of a concrete breaker is measured in Joules (J). The higher the joules level, the denser the material you will be able to break. This, combined with a high impact rate, makes for a concrete breaker powerful enough to work through most surfaces.
By law, all vibrating tools must have some level of anti-vibration system built into them. AVTs allow workers to work safer for longer and not cause any lasting injuries. To protect yourself or other employees, it is always worth choosing the highest quality equipment that is tested regularly.
There are 3 main types of chisels that are available for a concrete breaker, all of which can be interchangeable during operation.
Pointed chisels are used in a concrete breaker to apply as much force as possible through a small single point. This is the most common chisel you will expect to see being used with a concrete breaker, as they are ideal for the densest of surfaces.
Flat chisels are perfect to use up against a flat edge or a straight line cut. You can use a flat chisel to remove tiles from a wall or floor, as well as breaking concrete slabs. Using a flat chisel on dense concrete could be unproductive. However, if you are required to do so, always opt for a smaller flat chisel that can generate more focused force.
