Using a wire brush to polish rusty materials or a hacksaw to cut light metal structures is certainly possible, but having a high quality grinder for every task will make your life easier. The 4.5 inch angle grinder is a rough hand tool that can cut everything from steel structures to mild steel, masonry, and even tiles.
However, the choice of the right crusher that will overcome these hard materials and pass through them largely depends on the angle of the chosen crusher. This means that it’s not always easy to find the right person, at least if you’re looking for more than the price.
So let’s take a look at our top-of-the-line angle grinders to see what we’re talking about and which 4 1/2 angle grinders are right for you.
Dewalt DWE402 is very popular. The DWE402 is equipped with a powerful motor and a super-light grinder so that this little yellow-black cordless angle grinder is controlled by the wind.
The Dewalt DWE402 is also available at an affordable price. Although it may not be the cheapest 4 1/2 angle grinder on the market, the value you get and the reliability Dewalt constantly offers with its line of tools is simply priceless.
The Dewalt angle grinder DWE402 has sufficient power for light tools. Its new generation of 11-A engines are powerful and reliable. The motor can generate up to 11,000 revolutions per minute without load. The DWE402 is really designed for abuse. There’s nothing you can’t put in front of the DWE402 that it won’t eat with ease.
Even better: This model accommodates 5/8 and 7/8 wheels thanks to the chuck mounting structure. But where the Dewalt DWE402 really shines – in comfort and ease of use.
The DWE402 is equipped with an extra handle that is very comfortable and pleasant to use. This means you can use it on both sides and create extra balance at the same time. The slim body structure was supposed to help reduce fatigue and Dewald seemed to pay close attention to the ergonomics of the DWE402, with the handles shining on both the body and the extra handle.
Secondly, the DWE402 is relatively quiet compared to other 4.5-inch breakers, and you honestly have no idea that the 11-amp Dewalt motor generates 1400 watts in your hand. You may also appreciate that there is a locking switch that allows the engine to run continuously for as long as you need it.
The DWE402 works with a paddle switch located on the housing of the grinder. By clicking the safety switch and pressing the paddle switch, this 4.5 sander comes to life like a deer in the heat. The outstanding design of the DWE402 is something surprising, thanks to its slim ergonomic structure and perfectly positioned paddle switch. When you have this thing handy, you will really appreciate the exceptional build quality and literally be amazed by the performance of this 4.5 sander.
In addition to its performance and design, the DWE402 is also distinguished by its dust emission system. This unique feature improves the durability of the 11-amp Dewalt motor by removing dust or dirt that can penetrate the tool. This dust extraction system helps prolong the life of the motor by protecting the brushes and provides greater airflow across the motor, keeping it much cooler under heavy load.
And to make it even more fun, Dewalt also advertises its distinctive case and handy key to change discs faster and safer.
- Professional angle grinder at an advantageous price for the do-it-yourselfer
- The Dewalt One-Touch Guard™ allows you to quickly rotate the protective cover through 360°.
- Improved engine performance and durability through the dust ejection system™.

The Metabo WP9-115 has one of the most powerful engines in its class. This 4-1/2 angle grinder is ideal for material removal, grinding and even cutting tiles, metal or concrete, provided the right discs are used.
The WP9-115 has long received enthusiastic criticism from loyal Metabo users, and rightly so. It’s just one of the best angle grinders, and after using the WP9-115 for the first time, you will undoubtedly retain the same experience.
WP9-115 has a number of functions and features that are unique to Metabo. One of the most important functions is the Metabo S-Automatic safety function. It is essentially a skid safety clutch that improves operational control and reduces the risk of kickback. Something you probably encounter when cutting high-density wood.
Another interesting feature is the Metabo fast system. This is a disc changing system that makes a conventional key superfluous. Just press the button to erase the disc.
Sustainability is another important sign. The quality of the assembly is superior or at least close to that of such a number of 4 1/2 wedge guides at average and higher prices. The wear resistance is also noticeable in the motor, which has a 20% higher overload capacity.
The deadman switch is also part of the design. This makes it easier to switch off the engine quickly when the switch is released. Another thing that might be of interest to you is that the WP9-115 can work with both AC and DC power.
This is very important for both portability and overall benefit. And the fact that the motor has optimum airflow and lower operating temperatures makes the WP9-115 an excellent choice for use in harsh operating and environmental conditions.

It is often not possible to find an angle grinder that is most suitable for cutting and polishing complex workpieces as well as fittings or works of art.

If you have a limited budget and are looking for something cheaper on the market, the CRAFTSMAN CMEG100 4-1/2 inch angle grinder may be the best choice for you.
The CMEG100 comes with a reasonable amount of accessories and a lot of power to cut and grind through a variety of rough and durable materials.
Although affordability can be an important consideration for many consumers when considering a CRAFTSMAN power tool, the CMEG100 is more than just an attractive price tag. The CMEG100 is not on the list of the best angle grinders because it generates 12,000 rpm with a 6-A motor, but because it generates 12,000 rpm and does not break the bench.
Now that we have established that the CMEG100 actually produces a very impressive amount of power for an angle grinder, do you need to think about a compromise? In short, this is the quality of CRAFTSMAN’s CMEG100 assembly. This shredder is specially designed for people who work at home, not for the daily needs on the construction site.
Please note that the CMEG100 is not inferior in its overall design and construction, it is simply not designed to perform heavy-duty tasks that most owners will never do themselves. It is made as a glossy starter with all the necessary accessories such as a key, a three-sided additional handle, a carbon brush and a grinding wheel. The cutting and grinding wheel supplied with the CMEG100 is strong enough to support you for some time.
A spindle lock is available for easy wheel change and to improve control and accuracy during over welding. The reformed and profiled additional handle can be mounted either on the side or on top. As with all models with a 3-position handle, this allows you to use more technologies and work in hard-to-reach places.
The grinding guard of the CMEG100 has a tool-free adjustment function that can be easily adjusted in seconds by unlocking the handle and turning the protective cover. This small, simple but convenient feature significantly improves productivity because you don’t have to search for a special tool to make the necessary adjustments.
Another striking feature of the CMEG100 is the additional advantage of the VERSATRACK wall organization system, which allows the disposer to be carefully folded into the frame and stacked using the CRAFTSMAN hook and accessories that can be purchased separately.

If it is a wire-bound angle grinder, it must be a Dewalt DWE402 4-1/2 inch angle grinder, no doubt. Do-it-yourselfers and professional contractors have long regarded it as one of the best angle grinders.
The Dewalt DWE402 is the kind of grinder you see hidden in a mechanical toolbox or in a temporary socket on a construction site. That’s really good!
If you are more interested in battery powered angle grinders and want our opinion on the best wireless angle grinder, you should definitely take a look at the Milwaukee 2780-20 M18 gas-powered angle grinder.
This complete savage weighs about 5 pounds with the M18 battery connected, which generates more than 8,500 rpm thanks to the patented brushless motor Powerstate™.
Obviously, yes. You can use a 4-inch blade on a 4-1/2-inch shredder. As long as the wheel is compatible with the pavilion, a 4-inch wheel can be successfully installed on a 4-1/2-inch wheel. Another thing to consider before placing a small wheel on a large grinder is to make sure that the wheel you are using is actually designed for the speed of your grinder.
A typical 4.5 inch angle grinder produces about 11,000 rpm and a significant number of discs you will encounter are about 13,000 rpm. But with 5-inch angle grinders, the revs are between 7500 and 9000 rpm. In other words: You can use a small disc on a large sander without worrying about it getting jammed.
The last thing to think about is the use of discs of different sizes on angle grinders. If you accidentally use a 5-inch hard drive for a long period of time, it will eventually become a 4 1/2-inch hard drive, then a 4-inch hard drive and then a 3 1/2-inch hard drive, and so on. You know the drill.
It is difficult to choose the winner from this series of angle grinders. But if necessary, the best angle grinder in the 4-1/2 inch range should be the DEWALT DWE402 4-1/2 inch angle grinder. With a speed of 11,000 rpm, this 4.5-inch grinder is truly ideal for various grinding, cutting and grinding methods at relatively low cost.
A power tool like the DEWALT DWE402 has built a reputation that precedes it. As you grind and cut the DWE402 in the afternoon, you will undoubtedly understand the hectic pace.
Every angle grinder considered today, like any power tool, has its advantages and disadvantages. When buying an instrument, there will almost always be a compromise.
But if you can choose an instrument that respects your budget and meets your needs, the uncomfortable nuances that we have highlighted or that you will experience for yourself will only come into play when you feel comfortable with the instrument.
