— Husqvarna Husqvarna 967181002 K760 II 14-inch Gas Cut-Off Saw
https://www.amazon.com/Husqvarna-967181002-K760-14-inch-Cut-Off/dp/B00DI72XFW/
Husqvarna is by far the oldest and most experienced company on our list with a storied history that stretches back centuries. That said, the company did not start making power tools until somewhat more recently and is not necessarily the most experienced in this aspect. Still, Husqvarna did at least begin their line of construction tools with power cutters making this one of their most developed product lines. It is also worth noting that Husqvarna prides itself on producing some of the most powerful tools for their given markets and puts plenty of time, energy, and resources into innovating their tools for both function and experience. Husqvarna may charge a good bit more for their power cutter than some of the other companies we came across, but they also back it up.

Excellent Cuts
While no power cutter is designed for every stone-cutting task, a capable handler can usually manage to do everything with the right tool. That said, this often entails making sure that a power cutter can handle the high-end of rigor more than anything else. In this regard, there are few power cutters on the market that can truly compete with the Husqvarna K 760 II concrete saw. For one, this is a gas-powered cut-off saw that uses a 2-stroke engine to generate plenty of power. This is important because a 2-stroke engine is able to achieve higher rpms and generate more torque, which has an outsized impact on cutting power, compared to a 4-stroke engine.

While a 2-stroke engine does generate more power than a comparable 4-stroke engine, it also has to deal with less efficient combustion. Thankfully, the Husqvarna concrete saw manages to keep emissions down and fuel efficiency high without sacrificing power due to its patented X-Torq technology. In fact, the Husqvarna cut-off saw is able to generate the most cutting power that we found with a 5 hp engine. To be fair, it does not hurt that the Husqvarna cut-off saw comes with a massive 73.5 cc engine. These mechanical qualities all combine with a large 14” blade to allow the K 760 II power cutter to make the deepest cuts on our list at 5”.

Great Build
While the ability to make powerful cuts is one of the necessary hallmarks of a high-end concrete saw, this kind of power tool generally endures a great deal of abuse along the way. As such, the K 760 II concrete saw also makes it a point to offer a build quality that is easier to maintain and can handle a heavier workload than many of the other products on our list. For example, the Husqvarna power cutter uses a fully sealed transmission system with a poly-v drive belt. This prevents dust from getting into the gear works while also providing a smoother operation. To further prevent dust from messing with the K 760 II power cutter’s operation, the start system is also sealed.

Taking this protected build a step further, the K 760 II cut-off saw also comes with a patented SmartCarb filter compensation. This works to keep dust out of the air filter without reducing the amount of cutting power generated. Of course, the air filtration system itself is fairly robust thanks to the Active Air Filtration which uses centrifugal force from the engine to help keep the air filter clear of any larger debris of heavy dusting. Beyond taking care of the Husqvarna K 760 II power cutter, this concrete saw also looks after the user as well. With a combination of the poly-v belt system and the Husqvarna concrete saw’s Anti-Vib feature, this cut-off saw can generate significant amounts of cutting power without wearing on the user as much as some other concrete saws may.

— Pros
Is a gas-powered concrete saw
Has 5hp of cutting power
Has an anti-vibration system
Has an advanced engine
Has an advanced drive
Has an advanced water system

— Cons
Is a more expensive concrete saw
Not the easiest to start

– Top Pick
— Makita EK7651H 14-Inch MM4 4 Stroke Power Cutter
https://www.amazon.com/Makita-EK7651H-14-Inch-Stroke-Cutter/dp/B00D4NTLMS/
While Makita may not be the oldest company on our list, they do still have plenty of experience being founded over 100 years ago. To be fair, the company actually started as a maker of electric motors but quickly expanded into the contractor too market. On the other hand, the Makita MM4 power cutter definitely takes a different design approach from most of their products’ general philosophy. However, one thing that has not changed with this concrete saw’s design is Makita’s impressive attention to power. Even better, the Makita MM4 concrete saw also takes into account the difficult task of a cut-off saw better than most. While it is one of the more expensive concrete saws that we reviewed, there is no mistaking why we rated this as our top pick.

Excellent Build
Compared to the best seller concrete saw, the Makita power cutter is a bit of a mirror image. By that, we mean that where one produces more power with a good build, the other has a better build but still produces plenty of power. The Makita cut-off saw definitely makes it a point to outdo most other competitors in the build-quality arena. From beginning to end, not only is the MM4 cut-off saw more durable than most of the other products we reviewed, but it is also one of the easier to use and maintain. This begins with one of the better start systems that we came across that is not only easier to engage but also has a pressure compensated carburetor and vented choke to prevent flooding the engine during cold starts. As if that was not enough, the Makita concrete saw also features a 4-point anti-vibration system to help reduce user fatigue. To complement the anti-vibration system, the MM4 concrete saw also comes with fully-integrated aluminum wheels for longer cuts– though they do not cover the entire base like with some cut-off saws.
Beyond the features designed to make using the Makita MM4 power cutter easier, there are a number of qualities that make it more durable as well. This is especially important considering that the MM4 power cutter is designed for professional-grade jobs. This begins with sealing or protecting most of the exterior exposed sections of the tool including a sealed starter system as well as a shielded exhaust to prevent dust from getting in. Of course, that should not be as much of an issue considering that the Makita power cutter also comes with a 5-stage air filtration system that directs the internal airflow better than most. Inside the Makita concrete saw, the engine uses a 3-ring piston system to provide commercial-grade engine durability. This is complemented with specially treated rods, followers, and valves to increase engine durability even further. Finally, an oil and lubrication separation system increases the lifespan of the engine and valve train while reduced exhaust and carbon intake extend the life of the cylinders.

Great Cuts
It is not often that Makita gets bested in terms of generating power, but it is actually the second most powerful concrete saw on our list. That said, this is due to an uncommon design choice that comes with its own benefits and does not actually impact the cutting power too much. Specifically, this one of the few gas-powered concrete saws, and the only one on our list, that uses a 4-stroke engine instead of a 2-stroke engine. While this does reduce the rpms and torque generated a bit, it also makes fueling the Makita concrete saw much easier without having to mix oil with the fuel. On top of that, a 4-stroke engine is also significantly more fuel-efficient which will help lower the operating costs in the long run.
Beyond the fact that the MM4 concrete saw uses a 4-stroke engine, it also comes with the largest engine on our list at 75.6 cc. This likely a big part of why it can use a 4-stroke engine but still generate 4 hp or cutting power and slice through concrete with ease. However, the impressive cutting power with an efficiency engine is not the only solid advantage the Makita power cutter offers for cuts. While not the largest that we reviewed, the MM4 power cutter is still able to make deeper cuts than most at 4 13/16” thanks to its 14” blade. On top of that, this is actually one of the few cut-off saws that we reviewed which allows you to reposition the blade to make flush cuts.

— Pros
Is a gas-powered concrete saw
Has a 4-stroke engine
Has 4hp of cutting power
Has 5-stage filtration
Is more durable than most
Is an efficient concrete saw

— Cons
Is a more expensive concrete saw
Is a heavier concrete saw

— Evolution DISCCUT1 12″ Disc Cutter, Orange
https://www.amazon.com/Evolution-DISCCUT1-12-Inch-Cutter-Orange/dp/B003K4FQ6G/
Evolution Tools is definitely a bit different than most of the other companies we reviewed as it youngest by far with only a couple of decades of experience. That said, the company does make it a point to offer a wide range of different contractor options including a specialized consumer-grade brand as well as non-wood cutting tools too. Though, it should be noted that the Evolution DISCCUT1 concrete cutter falls within the professional-grade “builder” brand. That said, this is a more budget-friendly concrete saw and is definitely not meant to handle the projects that other professional-grade tools can.

Good Cuts
One thing that sets the Evolution concrete saw apart from the other options we already reviewed is that it is the first electric concrete saw on our list. While this means that you may not get quite as much cutting torque as with a gas-powered power cutter, this tool does not lack for power. For example, it comes with a solid 15-amp high-torque motor that can handle plenty of jobs, though you should not try to push it to the brink. Still, it offers a solid maximum cutting depth of 4” thanks to its 12” blade, but you may need to make more and shallower passes compared to some of the heartier products that we reviewed.

Okay Build
While the cutting power of the DISCCUT1 concrete saw can match most of the other options reviewed, the same cannot be said for its build quality. Thankfully, this has nothing to do with the motor, gear works, or other primary internal components. However, some of the other auxiliary components will not hold up under extreme use making this unsuitable for all-day use. On the other hand, the Evolution Tools concrete saw is one of the only products we found which uses a mid-position alignment which, when combined with an ergonomic soft-grip handle, makes it easier to use than some– especially for vertical cuts.

— Pros
Is a less expensive concrete saw
Is an electric concrete saw
Has a 15-amp motor
Has an ergonomic design
Has a 4” cutting depth
Has a blade speed of 5000 rpm

— Cons
Poor dust management
Is not the most durable

— Metabo HPT CM4SB2 Handheld 4″ Dry Cut Masonry Saw, Includes 4″ Diamond Blade, Cuts Pavers, Concrete, Tile & More, 11.6-Amp Motor, Soft Grip Handle, Compact & Lightweight, 1-Year Warranty
https://www.amazon.com/Metabo-HPT-CM4SB2-Handheld-Lightweight/dp/B07MZW1V8F/
Metabo is interesting in that the company has actually been around for a while with its founding in 1920. However, they are not the most well-known power tool manufacturer which is likely why they were recently acquired by Hitachi Koki. Metabo and Hitachi do have some notable overlap though, especially in regards to their market which sits squarely in the mid-tier range. It is worth noting that the Metabo concrete saw cannot compete with some of the other products we came across, but they do offer a different design which carries with it some unique advantages

Different Design
One of the more notable qualities of the Metabo cut-off saw is that it is the only product on our list to use a sidewinder design. This means that the CM4SB2 power cutter is an electric concrete saw with the motor position to the side of the blade. While this does reduce some of the torque it can generate, it also means that the Metabo CM4SB2 concrete saw can fit into smaller spaces than pretty much all of its competitors. Aside from the fact that it is significantly more compact than the other options we reviewed, it is also by far the lightest power cutter on our list at just over 6 pounds.

Okay Specs
As one of the least expensive options, the Metabo power cutter does at least provide plenty in the way of convenience. For example, the CM4SB2 cut-off saw generates the least vibrations at 1.4 m/s2 and the least amount of noise at only 85 dB. Still, the motor only puts out 11.6 amps, though this is not terribly underpowered or anything, but you will need to take it easier on this cut-off saw than some of the others that we reviewed. On top of that, this is also the only dry-cut exclusive concrete saw, though it does have a sealed armature coil and metal-seated ball bearings to increase durability.

— Pros
Is a less expensive concrete saw
Is an electric concrete saw
Is a lightweight concrete saw
Is a compact concrete saw
Has a low-vibration design
Is a durable concrete saw

— Cons
Is a less powerful concrete saw
Has a smaller cutting capacity

— SKILSAW SPT79-00 15-Amp MEDUSAW Worm Drive Saw for Concrete, 7″
https://www.amazon.com/SKILSAW-SPT79-00-15-Amp-MEDUSAW-Concrete/dp/B06W9NDKWQ/
SKILSAW is not the oldest company on our list, but it has been around for over 90 years. On top of that, the company is credited with making the first consumer-grade circular saw which is why skilsaw is often synonymous for circular saw. That said, the company has recently been acquired by BLACK+DECKER, though they did not see the same kind of impact on their quality that some other brands did. However, SKILSAW is still definitely a bit more of a consumer-grade to mid-tier brand, though the SKILSAW MEDUSAW concrete saw is definitely one of their better offerings.

Good Power
The MEDUSAW concrete saw definitely has a different design that affords it some unique specs compared to most. For one, this is an electric concrete saw, but it is still able to generate a surprising amount of cutting power. While not the most powerful cut-off saw we reviewed, the SKILSAW power cutter still comes with a 15-amp motor. On top of that, the MEDUSAW cut-off saw can get the most torque out of its motor with a worm drive design. The main issue with the MEDUSAW power cutter is that it has a shorter maximum cutting depth and cannot cut flush.

Good Build
While not the lightest product on our list, the SKILSAW concrete saw is still fairly lightweight at just over 16 pounds. Even better, all of the components are made of aluminum which helps keep the weight down without sacrificing durability. The foot, in particular, takes full advantage of this as it comes with rolling wheels to make its use that much easier as well as a wheeled front pointer for accuracy and precision. Despite its maximum cutting depth limitations, the SKILSAW cut-off saw also comes with a solid plunge-cut guide.

— Pros
Is a less expensive concrete saw
Is an electric concrete saw
Has a 15-amp motor
Has a worm drive
Has a rolling foot
Good dust management

— Cons
Has a smaller cutting capacity
Cannot cut flush

– Best Concrete Saw Buying Guide 2019
— Type
The type of concrete saw may not necessarily determine whether it is better or worse, but it will definitely impact when and where you should use it. Concrete saws come in both gas-powered and electric models with each having advantages and limitations. Gas-powered concrete saws are able to generate significantly more cutting power than electric models. This is part of the reason they often include larger blades and can cut deeper than most electric options. On the other hand, gas concrete saws are also much larger and more difficult to use in general, especially those with a 2-stroke engine.
Electric concrete saws, while less powerful than gas concrete saws, are not necessarily weak– though they do have more limitations. Specifically, you will not be able to use most electric concrete saws all day making the toughest cuts like you can with a gas concrete saw. On the other hand, electric concrete saws are generally easier to use which can come in handy when making vertical cuts. On top of that, electric concrete saws are also less expensive upfront and over the duration of its life since they do not require fuel beyond an outlet.

— Drive
While the drive of a power saw is not always the most important factor, it actually weighs heavier for a concrete saw than many other types of power saws. This is because a concrete saw needs more cutting power, specifically more torque, than most other types of power saws. The 3 main types of drive used for concrete saws is the worm drive, the sidewinder, and the belt drive, though many concrete saws may use both a belt and worm drive arrangement.
Of the 3, the worm drive is generally able to generate the most cutting power, but it also suffers from less control and more vibration. The sidewinder attempt to mitigate some of these control issues by placing the gears next to the motor or engine, though this does very little to account for the increased vibration and reduces the cutting torque. The belt drive system is easily the smoothest operating, significantly reducing the vibration, but it can also reduce the torque too.

— Cutting Capacity
While cutting capacity is generally one of the more important qualities when choosing a common power saw, it really depends on what kind of cutting you expect to do. If you use your concrete saw most for cutting into floors, there is a good chance that you may not need the deepest cutting capacity. That said, if you need a concrete saw for cutting vertical or for many outdoor applications, you will likely require a deeper maximum cutting capacity. It is also worth looking into a plunge cut indicator which helps keep your cuts at a specific depth, though this is not as often found on deeper cutting concrete saws.

— Dust Management
Dust management is arguably one of the more important factors to consider when choosing a concrete saw due to the particular requirements of cutting into masonry. Basically, cutting stone generates far more heat than cutting wood which will either require a water system or frequent breaks between each cut. A water system does a decent job of getting the dust out of the way, though it can technically also wear the blade quicker if the dust is driven into the cut. Vacuum dust management is used for cry cutting, but it can be notoriously unreliable and does not cool off the blade.

— FAQ’s
Why Choose a Concrete Saw?
To be clear, concrete saws are not the only kind of power saws that can cut masonry, but they definitely provide more versatility in terms of stone-cutting tasks. Keep in mind, if you have a smaller stone-cutting job that does not require you to cut deeper than 1” to 1 ½”, you are probably better off using a capable circular saw with a diamond blade made for cutting stone. However, there are a number of circumstances where a concrete saw simply outshines other power saws, regardless of the blade they use.
Easily one of the more notable instances indicated for using a concrete saw comes with controlled demolition. Keep in mind, industrial concrete demolition can use a jackhammer or other similar tools, but residential, and even some commercial, concrete demolition are usually better served with a concrete saw. Aside from the fact that concrete saws cut stone without inherently breaking it unevenly, most residential stonework will not exceed the standard cutting ranges of a concrete saw.
Beyond general demolition, concrete saws are also effective for cutting into stone for decorative or even repairing purposes. If you need to cut into a sidewalk or patio but are not actually pulling the entire slab up, a concrete saw allows you to cut far more precisely than larger tools. Inside of your home, a concrete saw can allow you to replace floors, countertops, and even patch or repair a standing wall. That said, you will generally need a larger type of tool for anything exceeding 4” to 5” in depth.

How to Use a Concrete Saw?
While a concrete saw may perform an ostensibly similar function as a wood-cutting saw, the actual techniques used to accomplish the task are a little bit different due to the distinctive qualities of stone. Furthermore, concrete saws are also often used to cut other materials as well, whether embedded in stone or on their own. Moreover, because concrete saws are often used for demolition purposes, you may need to make particular cuts with them that you otherwise would not make with most wood-cutting saws.
Easily one of the more important things to ensure when working with a concrete saw is the designed cutting materials. While all concrete saws can cut stone and other masonry, some of them are also able to cut various types of metal. You will generally want this feature when cutting stone that has a rebar skeleton, but concrete saws are just as regularly used for cutting large pipes too. However, not all concrete saws can cut such a wide range of materials, regardless of the specific saw blade attached.
That said, regardless of the type of materials the saw can make, there are a couple of techniques you should use when cutting masonry with a concrete saw. Keep in mind, you likely should not use a concrete saw when a smaller masonry saw, like a tile saw, will do. However, if you need to make a deeper cut than a tile saw affords, the concrete saw is a potentially necessary tool. The main thing to keep in mind when cutting masonry with a concrete saw is to take your time as masonry is significantly harder.
This holds true even if you have the best stone-cutting blade attached to your concrete saw. Basically, most concrete saws will require you to make multiple passes over the masonry being cut to achieve any significant depth of cut. Whether or not you manually score the concrete, make sure that your first pass is no deeper than 1” with ½” to ¼” being perfectly acceptable. Once you make your first cut, make multiple passes at ½” to ¼” per pass until you cut to the desired depth.

What to Look for?
While a number of different qualities and features already covered will depend more on your budget, experience, and job, there are a couple of things to always look for in any concrete saw. By far one of the most important is a well-designed motor and gear works, though the specific configuration is not necessarily important. Instead, you will want to make sure that as many of the internal components are shielded from water, dust, or debris depending on the concrete saw in question. While sawdust can definitely pose an issue for traditional power saws, masonry dust is far more invasive and even more difficult to clean if it gets in the tool.
Also, while cutting power is always important for a power saw, it is arguably more important for a concrete saw than many other types of power saws. For one, most concrete saws are not necessarily expected to provide the same kind of precise finish that many wood-cutting saws do. However, almost every concrete saw needs to be strong enough to cut through a variety of different masonry materials. It is worth noting, though, that there are multiple ways of achieving cutting power, and the motor or engine is not always the single determining factor.

— Conclusion
Ultimately the best concrete saw will hinge as much on the actual job you have as the quality of the saw itself. If you need a concrete saw for incredibly large jobs that will tax most other saws to the limit, the Husqvarna has the power that you need. Similarly, the Makita also provides a significant amount of power for larger jobs but has a slightly smaller cutting depth combined with more durability. The Evolution Tools comes in at a reasonable price, but it is definitely meant to be used for homeowner purposes exclusively. The Metabo may not be able to compete with many of the other options on our list in terms of raw cutting power, but it is much easier to use in confined spaces. Finally, the SKILSAW provides more power than other electric concrete saws, but it also has a smaller maximum cutting depth.
