Concrete saws can be difficult to shop for online. They can feel like one of those tools that you really need to hold to get a good feel for, and manufacturer descriptions aren’t known for being forthcoming when it comes to flaws.
However, we think that a well-informed buyer can make a great decision and get a model that’s just right for them if they know everything they need to know. That’s why we’ve created this list of reviews of the best concrete saws of 2019. After reading these reviews and the attached buyer’s guide, you should be able to find a model that won’t break the bank, and you’ll love using, too.
|Husqvarna 967181002 K760 II Gas|
|Makita EK7651H 14-Inch MM4 Gas||28 lbs||4.5/5|
(Best for the Money)
|Hitachi CM4SB2||8 lbs||4.2/5|
|SKILSAW SPT79-00 Worm Drive Saw||17 lbs||3.9/5|
The Husqvarna 967181002 is a good choice for anyone who needs a great concrete saw that is strong enough to complete any task that you throw at it. Power isn’t a problem with this model, which comes with a massive five horsepower motor. However, it’s not only powerful, but it’s also gas efficient, as it features X-Torq engine tech, which reduces fuel consumption by about 20 percent and engine emissions by up to 75 percent, which makes for a lower cost of operation and less noxious fumes to breathe in.
It’s also a low-vibration unit, which means that you won’t feel worn out as quickly with this model as you would with a similar one that vibrates more. It also includes active air filtration and a dust-sealed starter, which extends the life of the engine by filtering out dust, which you make a lot of when you cut concrete. The only knock against this model is that it needs to have just the right fuel mix before it will start the first time, which can be frustrating, even if it starts quickly from then on. Overall, this is the best saw on the market for most people.
The Makita EK7651H 14-Inch MM4 concrete saw changes out the two-stroke engine found in most gas-powered saws for a four-stroke engine. While this doesn’t lead to a direct increase in power, it does have a host of other benefits. For instance, you can use regular gas in a four-stroke engine, as opposed to the 50:1 gas to oil mix needed in two-stroke engines. That means you won’t have to mix gas and oil before use, and you won’t ever accidentally burn out the motor with the wrong ratio.
While no saw of this power could ever be described as “quiet,” this model is quieter than competing saws of a similar size, which is something you’ll appreciate while you’re using it. It also comes with a five-stage foam-paper-nylon filtration system which does an excellent job of keeping dust out of the engine and greatly extends its life. However, this model is very slow starting, sometimes requiring five or more pulls to turn over. It also costs hundreds of dollars more than our top model. It’s powerful, however, so you must decide if you value the four-stroke engine at such a premium over a two-stroke with similar power.
The Evolution DISCCUT1 is a great choice for people looking to get a good deal on a concrete saw and like the idea of doing less maintenance than they would on a gas-powered saw. This model is electric, which brings a host of benefits over a gas-powered model. A significant one is that you don’t have to use gas, which significantly lowers the cost of operation in this model over time. You also don’t have to do as much maintenance, as an electric motor has fewer moving parts, and will break down less often.
This model also comes with a spindle mechanism, which makes changing out blades extremely quick, which is a good feature to have if you’re planning to use different blades for different projects, or for different materials in the same project. It also comes at a fraction of the first two models’ cost, making it a great deal. What keeps it out of the top two is that it’s a corded electric tool, which means you need a source of electric power to use it, which makes it less portable. It’s a good tool, but it’s not yet portable enough to come in first or second.
The Hitachi CM4SB2 is one of the more portable models on our list, but it has some significant flaws that cost it positions on our list. It is a circular saw, which means it functions differently from the other models so far. It has easy depth adjustment with a one-touch level, which comes in handy if you’re only cutting part of the way through something. It’s also low-vibration, which means you can last longer with this tool than you’d want to with others. It also weighs between half and a third of what other models on this list weigh, which makes it a good choice for anyone who doesn’t want to be worn out by their tools.
However, this is a circular saw, and it lacks any kind of bevel adjustment. There are some complaints about the saw not coming at a perfect 90-degree angle, so there’s some potential for frustration there, especially if the job you’re doing needs perfect 90-degree cuts. Likewise, it has average power at best. This isn’t a tool with industrial-power, so it’s a good choice for people doing jobs at home but lacks the power for many kinds of construction work.
The SKILSAW SPT79-00 Worm Drive Saw is, as the name would suggest, a worm drive saw. This means it’s narrower and longer than a direct drive circular saw. That makes it better for cuts in tight spaces, and typically means that it cuts a bit better with the same amount of power used. This model is electric, which means it’s low maintenance, but also that you need to have a power outlet available if you want to use this saw. It comes with retractable pointer guides, which make following a pre-drawn line very easy.
This model is compatible with a dry or wet dust management system, and it’s GFCI protected, so you’re safe to use water with it even though its an electric tool. However, the dry dust management system doesn’t work the best and results in lots of dust getting left behind. It can also only support 7″ blades. That means you won’t get nearly as much depth as you would with our top models, which use 12″ or 14″ blades. Overall, this model has its uses, but you’re not going to get the same depth or the same speed you’d get with a bigger saw.
Hopefully, our reviews already have you thinking about what features you’d like to see in your next concrete saw. There are many features you need to consider before you buy, so if you’re not sure how to go about picking the right model for yourself, check out this buyer’s guide. We’ve filled it with great information about evaluating concrete saws, as well as tips for picking the right one for you. It’s also a good resource to check out if you’ve never bought a concrete saw before, or if you haven’t bought one in a long time and want to see what’s new on the market before you buy.
Electric tools have been around for a while, but they’ve made a big push in the last few years because of advancements in electric engines and batteries. While you’d be hard-pressed to find a concrete saw that uses a battery, some corded electric models are worth your consideration.
Corded electric models tend to be far lighter than gas-powered models. They don’t have a fuel tank, which cuts down on both weight and bulk, and the electric engine itself is more compact and weights much less. While it’s hard to find a heavy-duty concrete saw that weighs less than 20 pounds, you can often find electric models that weigh less than ten pounds, meaning they could weigh as little as one-third as much as an equivalent gas-powered model.
They also don’t produce any kind of emissions, so they’re better for the environment and better for people who are sensitive to gas fumes. Since they don’t have any moving parts, they don’t need as much maintenance, and break down less often, meaning they can be a less frustrating model in the long run. However, you have to keep in mind that these models require an electric outlet, so you’ll need to have access to a power supply to use them.
Gas-powered models are the clear winners when it comes to portability. While they often weigh more, they don’t use a power cord, so they’re good for situations where you won’t have easy access to power. The models with the most power are all gas-powered, so if you’re looking for something for industrial or construction use, you’ll want to get a gas-powered concrete saw. More power also means more speed in the same job relative to an electric model, so gas-powered is the way to go if speed is of the essence.
You should keep in mind that gas-powered concrete saws can come with two-stroke or four-stroke engines, which have different requirements that are explained in the section below.
Two-stroke engines tend to be more common in handheld power tools than four-stroke engines. While the name may seem to imply that the four-stroke engine is more powerful than the two-stroke engine, this isn’t the case. Instead, the number of strokes refers to the way in which the engines use oil for lubrication.
The four-stroke engine has two extra strokes that are dedicated to lubricating the moving parts with oil. This reduces wear on the parts relative to a two-stroke engine, and it means that four-stroke engines should last longer. It also means that they have more moving parts, which means more can go wrong, but if you care for it properly, you should see a longer life out of a four-stroke engine than a similar two-stroke.
You can use standard gasoline with a four-stroke engine, though you will likely want to find a gas station that doesn’t add ethanol into the mix as smaller four-stroke engines frequently don’t handle it well. You also have to add engine oil through a separate valve on the tool.
Two-stroke engines don’t have as many moving parts, so they tend to be far smaller. They also tend to start much more quickly. Usually, one or two pulls is enough to start them, as opposed to four-stroke engines which often require far more. They can’t use standard gas, however. They need to have gas and oil mixed together before it’s poured into the fuel tank, and that means that you either need to buy a special blend or do the mixing yourself.
Typically, that means a blend that’s 50:1 gas to oil, though that does vary sometimes. However, you don’t need to add discrete oil as all the oil the engine needs is already in the gas. Two-stroke engines won’t last as long as four-stroke, so you shouldn’t expect them to last forever, but good models should give you many years of excellent service. Two-stroke engines also have better fuel economy and produce less fumes, so if you want a model that excellent in those areas, go with a two-stroke engine.
The Husqvarna 967181002 is our top model due to its low vibration, active air filtration, and low fuel consumption. The Makita EK7651H 14-Inch MM4 concrete saw is a good choice for people who want a four-stroke engine but is likely to be too pricey for people who don’t have a preference between two-stroke and four-stroke engines. The Evolution DISCCUT1 is a great electric model available at a low price, making it the best value on our list. The Hitachi CM4SB2 is lightweight and features depth adjustment but doesn’t have the power needed for serious construction work. The SKILSAW SPT79-00 Worm Drive Saw can work with wet or dry dust management systems, a great feature for an electric concrete saw, but its small blade limits its usefulness.
We hope that our reviews and buyer’s guide have helped you learn about concrete saws. Armed with this information, you should be able to find the perfect model for you.
