[newly uploaded] The Only Walk-Behind Concrete Grinder You Need

Do you need a walk-behind concrete grinder? The answer to that question is probably yes. There are many reasons why you may need one, but the most popular reason is for jobs that require grinding and polishing of concrete slabs.

This article will talk about how to choose the right grinder for your needs and what some of the best models on the market are.

How Does A Walk-Behind Concrete Grinder Work?

A walk-behind concrete grinder has either one or two drums covered with diamond impregnated segments.

As the machine slowly moves, the top edge of the drum rotates and presses against the concrete surface to be polished.

The grinding action removes mill scale, dirt, rust stains, and other imperfections from any concrete floor until it is smooth enough to apply new concrete.

This is how the walk-behind concrete grinder works. The machine slowly crawls across the floor and grinds off any rough spots on your floor, leaving an even surface in its wake, ready for a skim coat of fresh concrete.

Although it operates somewhat like a large rotary floor machine, a walk-behind concrete grinder is significantly smaller.

It also has only two wheels, as opposed to the larger machine’s four, making it easier to maneuver around obstacles and harder for pedestrians to trip over.

What Do You Know About The Concrete Grinding Process?

Concrete grinding is the act of using a machine to cut grooves into your concrete surface. A grinder with diamond-impregnated segments slowly crawls across the floor at about 1/16th of an inch per second, removing any imperfections in its wake.

The process begins by getting rid of the top layer of the existing concrete and flooring. This is typically done with a hydraulically-powered saw blade, which can cut through virtually any type of concrete.

After the top layer has been removed, the grinding begins. The grinder covers your existing surface area in an even pattern, removing any rough spots or bumps left behind by the saw blade.

It can take hours, depending on the size of your concrete surface area. It’s also best to have multiple workers involved in the process to go more quickly, although machines with two drums are now available.

Why Is There A Need For A Walk-Behind Concrete Grinder?

Does anyone need to grind their concrete? Isn’t that what companies are for? Well, yes and no. If you have a lot of concrete, it might not be cost-effective or even possible to have someone do it for you.

For example, if you only do the tiniest amount of grinding with an angle grinder, it will take you a long time and will be frustrating.

If you are planning on grinding a larger area, you might not have the space for a commercial unit or might not even fit through your doors or gates.

In addition, if low-level power lines are running along where you want to work, then again, commercial grinders won’t be able to use that area.

So, if you have a lot of concrete to grind, then the only real option is a walk-behind grinder for sale. It’ll save you time and effort compared with using an angle grinder, plus you don’t need loads of space or any fancy equipment either.

You can also get them reasonably cheap. a top brand can cost up to 20,000, but if you’re looking for a cheap walk-behind grinder or one that does, we have you covered.

What Do You Need For Grinding Concrete?

Before we talk about specific grinders, it’s essential to know what you’ll need to go with them. One of the most critical things with concrete grinding is the dust collection system.

You often have to cut out large sections of concrete so they can be replaced later on, but a dust collection system attached to your grinder help keep everything clean tidy.

Other than that, you probably want some safety equipment too. safety glasses are a must, and maybe even a helmet like this one or the surface you’re grinding might need some special guards to stop it from getting damaged.

Things To Consider For The Right Concrete Floor Grinder?

A floor grinder is an important machine, which you use to restore the look of your worn-out floors by grinding them down until they are smooth and shiny again.

It’s usually used in high traffic areas, such as shopping malls, airports, ports, warehouses, etc., but also to restore older floors with a beautiful, polished look.

Floor grinders are great for removing coatings and finishes from concrete floors, including paint or graffiti removal, to reveal a fresh layer of the concrete floor.

Types Of Concrete Grinders

There are three main types of floor grinders, the manual grinder, which is much like a portable drill with a special grinding head on it; there’s also the walk-behind machine or electric grinder which you push in front of you.

Both these models are suitable for small to medium-sized projects, but not large ones. The third type is the light commercial floor grinder, which is powerful enough to complete large projects, but still portable and easy to use.

If you’re looking for a new floor grinder, there are some important things you should consider before making your purchase:

What Type Of Work Will You Be Using It For?

If you need to make only small, minor repairs, go for the smaller models. However, if you need to do major grinding work or complete larger projects, choose one of the heavier machines.

Size And Weight

Grinders come in different sizes and weights.

Smaller machines are less heavy than larger floor grinders, so they’re better for jobs that don’t require much power. Choose a machine that’s easy to carry and lift, but still powerful enough for the job.

What Type Of Power Supply Do You Need?

Floor grinders can run on electricity or compressed air, so it’s important to know what kind of power source is available where you’ll be using it.

How Long Will The Machine Last?

When you go shopping for a floor grinder, it’s important to check the warranty and service agreements offered by the manufacturer.

This way you’ll have peace of mind knowing that your machine is well protected from any manufacturing defects or repair problems.

Are There Other Features You Need?

Depending on what kind of work you do, you may also need a bevel edge guide, work lights, or a vacuum system for collecting dust.

Weigh all your options against what you need to get done and choose accordingly. Check for variable speed control and self-adjusting floating cover with ergonomic work position and one-pass design.

What Sort Of Surfaces Can You Grind?

You can grind many concrete surfaces with a walk-behind concrete grinder, but if you are planning on doing commercial work, there are some limits. The ergonomically designed concrete grinder comes with interesting things.

You might not be able to grind certain types of concrete, such as the old-fashioned “wet set” cement. These surfaces are usually pretty tricky too. You might need a different attachment or maybe even an angle grinder instead for these areas.

Electric Powered Grinders Vs. Gas-Powered Grinders

One of the main advantages of electric-powered walk-behind concrete grinders is that adverse weather conditions do not impact them; if needed, you can still work, even when rain or snow is falling. As a result, you can work continuously during the winter season.

In addition, these grinders are very quiet and do not produce any visible emissions. Electric-powered concrete grinders have a lower carbon footprint than gas-powered ones since they don’t rely on gasoline or diesel fuel to operate.

Many users find that gas-powered grinders are easier to maneuver, mainly used on smaller projects.

They are also more lightweight than electric models, making them easier for some workers to handle. In contrast, others prefer an electric grinder’s greater power and torque that allows it to break up more rigid materials like cured concrete or asphalt.

Gas-powered walk-behind grinders usually have less vibration than electric models, making them less strenuous on the user.

In addition, they can be used in all weather conditions and do not require a power source other than the gas itself.

Those who work with concrete over a long period report that heavy-duty gas-powered grinders last longer and break down less frequently than electric ones.

On the other hand, gas-powered grinders are heavier, noisier, and emit emissions like carbon monoxide or hydrocarbon gases.

They can also be more challenging to maneuver than electric models, especially on hilly terrain or when used by workers with disabilities.

Gas-powered concrete grinders require regular maintenance to run smoothly; they often break down without them.

Conclusion

Are you tired of having to rent a concrete grinder for your jobs? You don’t have to anymore! We offer the best walk-behind concrete grinder that is perfect for any job. It’s easy to use and will get the job done quickly, saving you time and money on rentals.

There are many different grinders out there, so it can be challenging to know which one will work best for you.

2783-20 Milwaukee M18 FUEL Braking Angle Grinders, Paddle Switch

Similar to the 2883 Milwaukee ONE-KEY model above, but without ONE-KEY, the 2783-20 M18 FUEL Braking Angle Grinders power on with a paddle switch. The brake on this 8500 RPM grinder brings a cutting wheel to a stop in 0.9 seconds, a flap disc in 1.3 seconds, and a grinding disc in 1.5 seconds. With plenty of power, this tool makes sense to buy as tool-only and then add your own advanced RedLithium battery.

Milwaukee Tool seems to be closing out this grinder, so if you find one for less than 200 for the bare tool, grab it! The kits include two 5.0 batteries for 469.

2781-20 Milwaukee M18 FUEL Braking Angle Grinders, Slide Switch

Similar to the 2883 Milwaukee ONE-KEY model above, but without ONE-KEY, the 2783-20 M18 FUEL Braking Angle Grinders power on with a paddle switch. The brake on this 8500 RPM grinder brings a cutting wheel to a stop in 0.9 seconds, a flap disc in 1.3 seconds, and a grinding disc in 1.5 seconds.

2780-20 M18 FUEL Grinder, Paddle Switch

Replaced by the 2880-20 Milwaukee FUEL angle grinder above, the 2780-20 M18 FUEL paddle switch grinders offer a great deal if you can still find them. The wheel on this tool spins up to 8500 RPM thanks to the brushless motor and plenty of power. If you can find this as a tool-only purchase, you can add your own advanced RedLithium battery and add a very capable tool to your arsenal.

2680-20 M18 Cut-Off Grinder, Paddle Switch

As the only remaining brushed grinder in the Milwaukee Tool lineup, you can still find the 2680-20 for less than 120. That may make it the best bargain for those looking for a cut-off grinder that primarily cuts. As a grinding tool, you want to stick with one of the more recent models that use a brushless motor to better manage power delivery and runtime. With 8500 RPM of speed, you can make quick cuts in metal using this tool.

Milwaukee seems to keep selling this paddle switch model as an entry-level tool option. It lacks the isolating handle found on recent models. You can find it for under 120. In fact, we’ve seen the bare tool for less than 100 at authorized retailers.

Milwaukee M18 FUEL Cordless 5″ Flathead Braking Grinders

2887-20 M18 FUEL 5″ Flathead Braking Grinder, Slide Switch

The Milwaukee 2887-20 M18 FUEL 5″ Flathead Braking Angle Grinders feature a slide switch that lets you lock on the grinder when working for longer periods of time. This has the added benefit of letting you alter your grip on the tool for better positioning when needed.

Milwaukee claims these cordless angle grinders generate the equivalent power of an 11A corded grinder. Its low-profile design also means you can access tighter corners when grinding down welds or making cuts. This cordless angle grinder features the company’s RapidStop brake that stops the disc in just a couple of seconds when you disengage the switch.

The brushless motor spins the 5-inch grinder or flap disc at up to 8,500 RPM. Milwaukee recommends using their M18 RedLithium High Output XC6.0 batteries which run cooler, offer more power, and last longer than standard XC batteries. This tool runs about 279 as a bare tool with a contractor bag.

2886-20 M18 FUEL 5″ Flathead Braking Grinder, Paddle Switch

Identical to the above, but with a paddle switch, the Milwaukee 2886-20 M18 FUEL 5″ Flathead Braking Angle Grinder lacks the lock-on feature. It does, however, stop automatically when you release the paddle trigger.

Milwaukee claims this tool, like the slide-switch model, generates power equivalent to an 11A corded angle grinder. It has the same low-profile design so you can get tighter into corners when grinding or cutting. You also get the same RapidStop brake that stops the disc in just a couple of seconds when you release the paddle switch.

The brushless motor spins the 5-inch grinder or flap disc at up to 8,500 RPM. Milwaukee recommends using their M18 RedLithium High Output XC6.0 batteries which run cooler, offer more power, and last longer than standard XC batteries. This tool runs about 279 as a bare tool with a contractor bag.

Milwaukee M18 FUEL Cordless 6″ Braking Grinders

2980-20 M18 FUEL 6″ Braking Grinder, Paddle Switch

At one point, the Milwaukee 2980-20 M18 FUEL 6″ cordless braking angle grinders were their highest-performing small angle grinder. This grinder operates with the power of a 13-amp corded grinder. It also brakes all types of accessories (from flap discs to cutting wheels and grinding discs) in less than 3 seconds.

As the name implies, these angle grinders can support up to 6-inch discs (and go down to 4.5-inch discs when you don’t need that extra capacity). The brushless motor drives this grinder at up to 9,000 RPM. This tool excels at grinding, surface preparation, and cutting applications. Kit versions of this tool include either one or two RedLithium High Output XC6.0 batteries. Lastly, you get tool-free accessory changes using the FIXTEC nut and tool-free guard.

This tool runs about 229 as a bare tool and 479 with a pair of XC6.0 batteries, charger, and soft bag.

2981-20 M18 FUEL 6″ Braking Grinder, Slide Switch

The Milwaukee 2981-20 M18 FUEL 6-inch braking grinder pouts out the power of a corded 13-amp tool. It will stop flap discs, cutting wheels, and grinding discs in less than 3 seconds—making it extremely safe to use. The slide switch atop the tool lets you work for longer periods of time while adjusting your grip.

This angle grinder supports discs from 4-1/2 to 6 inches in diameter. The brushless motor spins discs at up to 9,000 RPM. Use this tool for grinding, surface prep, and cutting steel, rebar, and more. Kit versions of this tool include either one or two RedLithium High Output XC6.0 batteries. Milwaukee Tool also bakes in tool-free accessory changes with their FIXTEC nut and tool-free guard.

The 2981-20 6″ braking grinder runs about 229 as a bare tool and 479 with a pair of XC6.0 batteries, charger, and soft bag.

Milwaukee M18 FUEL Cordless 7″ – 9″ Large Angle Cordless Grinder

2785 M18 FUEL Large Angle Grinder

When Milwaukee Tool released the 2785-20 M18 FUEL cordless large angle grinder it was the world’s first 18V tool in its category. The 2785-20 puts out enough power to match 15-amp corded tools while shaving up to 2 pounds off the weight. With up to 9 inches of grinding capacity, it provides significantly more access and capability when grinding, doing surface preparation, or cutting larger diameter pipe and/or steel. You can use this tool with any 7- to 9-inch grinding or cutting accessories.

The brushless motor generates 6,600 RPM speed on the wheel (or higher) under load. Pairing this tool with the Milwaukee M18 High Output HD12.0 battery gets you the most amount of run-time possible across all applications. Lastly, you get quick accessory changes using the Milwaukee FIXTEC nut and tool-free guard adjustments.

Final Thoughts

When Milwaukee tool put out its first cordless angle grinder we found it lacking in both power and runtime. It freed you up from the cord but didn’t match the power of even mid-tier corded grinders. Now, however, the story appears much different. Between the M18 FUEL brushless models and newer Milwaukee Tool Redliythium Battery technology, their current crop of angle grinders offers plenty of power and runtime. Provided you have access to a pair of High Output batteries, you can get significant runtime for grinding, cutting, and surface prep tasks.

These tools have come a long way, and we hope the above list of products helps you understand the differences between the models so you can decide which makes sense for your needs.

Best Angle Grinder with Diamond Blade—DeWALT Angle Grinder

With a powerful 11-amp motor, this DeWALT 4.5-inch angle grinder boasts a lot of power. The blade can be used for dry or wet cutting while its DeWALT dust ejection system stops dust and debris from getting into the tool. It also features a paddle switch design, spindle lock button, tool-free wheel removal, and spiral bevel gear.

“This DeWALT angle grinder tool has a kick like a mule because it is that powerful,” wrote a customer. “It’s got torque like few other hand tools I’ve experienced. The revolutions on this thing are so fast it actually feels lighter when activated.”

Dust catcher: Yes

Motor power: 11-amp motor

Best Cordless Angle Grinder—DeWALT Cordless Angle Grinder

When looking through cordless angle grinders to buy, long battery life is usually top on the list of musts, which is why this DeWALT angle grinder with its brushless motor topped our list for the best cordless model. The kit includes the grinder, a Rapid charger, and a 60V battery. The variable speed works depending on how much pressure is placed on the power button, with light pressure for low speed and hard pressure to reach the maximum speed.

“Without question, this tool is a beast,” raved one reviewer. “It never bogged down under the most intense use and was light enough to make using it a pleasure. The power on this 60-volt model is exceptional—particularly considering it is battery powered.”

Best Corded Angle Grinder—BLACKDECKER Small Angle Grinder

There are many different ranges of power tools available for professionals and homeowners alike, so even those on a budget can find an affordable angle grinder for their needs—this BLACKDECKER power tool is a prime example. For under US30, shoppers can get this small angle grinder that has three different handle positions for a more firm grip for different projects.

It can be used with type 27 or 29 flap discs and comes with both a metal grinding wheel and a wheel guard. “Will cut through about anything,” described one shopper. “I use it on a regular basis when modifying my Jeep Cherokee, and when a large branch fell on my house, I grabbed it to cut through some limbs.”

Disc size: 4.5-inch angle grinder disc

Dust catcher: No

Best Pneumatic Angle Grinder—Ingersoll Rand Angle Grinder

Matching the power of a gas grinder, this pneumatic angle grinder from Ingersoll Rand is one of the more versatile tools buyers can add to their toolboxes. It can be used to polish, grind, sand, or hone a variety of materials, including wood, plastic, cast iron, or steel. Customers did note, however, that the guard for the blade does not come with the kit, and the different size holders and mandrels are sold separately.

“Build quality is exceptional—and I am a mechanical engineer who designs stuff like this for a living,” explained one shopper. “Very good ergonomics. The button to lock out the spindle for tool changes is much, much handier than I was expecting it to be. No more fumbling with two wrenches.”

Disc size: Most discs that are compatible with a ¼-inch shank size or 6mm collet

Dust catcher: No

Motor: 20,000 rpm

Best Powerful Angle Grinder—Makita Angle Grinder

Cordless tools with a powerful brushless motor, like this Makita angle grinder, offer the freedom and flexibility of working in tight spaces. The small diameter barrel grip on this versatile tool makes it easy to steady this machine even with the strong power output it gives. One customer felt that they would have preferred a trigger-style power switch but the overall consensus from the majority of customers was that this angle grinder is easy to use and a top product.

“I used it to cut out two 20-inch circles from 10 gauge expanded metal as grates in my burn barrels,” explained one customer. “Again, no problem whatsoever. Wore out one cut wheel and ¼ of the next.”

Disc size: 4.5-inch flap disc

Dust catcher: No

Other features include an electronic brake and an ergonomic three-position handle.

“No problem cutting through ¼-inch angle iron,” described one consumer. “Really like the three positions for the handle. I mainly bought it to grind, buff, and use with a wire wheel, but was pleasantly surprised at how well the battery did when it came to actually cutting.”

Disc Size: 4.5-inch angle grinder

Dust catcher: No

Motor: Brushless motor

Best Angle Grinder with Spindle Lock—DeWALT Paddle-Switch Angle Grinder

Using an angle grinder equipped with a spindle lock like the one found on this corded DeWALT grinder is a good safety feature when grinding for long periods. What’s more, the convenient paddle switch locks on for heavy-duty jobs. This tool doesn’t come with grinding wheels, and it does not have an electronic brake.

One customer who is a truck mechanic wrote, “I have put many quality grinders in their final resting place. [For] most of them, you could tell on day one what to expect. This one will be with me at home for the rest of my years. I fed this thing a hot supper for eight hours straight upon receipt.”

The size makes it deserving of a spot in tool bags, but be aware that the case can get hot with extended use. Buyers can also purchase this model with a dust ejection system for smooth operation. “Sweet grinder,” expressed one shopper. “Bigger amps than similarly-sized grinders. Fits the hand well.”

Disc size: 4.5 inches

Dust catcher: No

Motor: 8.5 amp motor

Best Variable Speed Angle Grinder—Makita Angle Grinder

The five variable speeds on this Makita angle grinder make it one of the more versatile grinders available. It can cut anything from granite to metal with different grinding wheels. The only caveat is that this grinder gets very hot when cutting thicker materials, so gloves should be used to protect the hands.

It comes with a three-year warranty. One reviewer expressed, “Drilled a three-inch hole in concrete as well as cut some four-inch cast with a diamond blade. Variable speed is worth every penny.”

Choosing the Best Angle Grinders—Buying Guide

Read on below to learn more about the different angle grinders and their best uses.

Types of Angle Grinders

There are four main types of angle grinders available, each with its own strengths, limitations, and type of power source. Most angle grinders can either be cordless, corded, gas-powered, or pneumatic.

Cordless Angle Grinders

Cordless power tools do not have the distance limitations of a power cord and allow operators the freedom of using them wherever they want, even outdoors. With battery technology improving every year, some cordless models are on-par, power-wise, with electric models. The only limitation of battery-powered grinders is if users don’t have a backup battery, then cordless grinders will generally only have a little over 45 minutes of run time.

Corded or Electric Angle Grinders

Corded models are one of the more popular types of angle grinders purchased for their power and unlimited power duration. A corded grinder is restrained by its cord, but for bigger jobs, a corded model doesn’t require batteries or the high maintenance needed for a pneumatic or gas power source angle grinder.

Pneumatic Angle Grinders

Pneumatic grinders work by using air pressure from an air compressor. When it comes to power levels, these would come just after gas-powered angle grinders and can be very expensive to own and operate, considering that air compressors have to be changed often because the refills are quite small and don’t hold that much air. One perk to a pneumatic version is that is tends to run longer than a cordless tool and is more powerful than a corded model.

Gas-Powered Angle Grinders

Like most gas-powered tools, gas angle grinders are the most powerful angle grinders available on the market. They are more expensive than other types of grinders and are also heavier. Additionally, gas-powered versions require a lot of maintenance and are not a top choice for smaller jobs.

We hope our review of the best angle grinders has been helpful, whether you were after something for heavy-duty projects or a model with the best safety features.
