Reviews Of The Best Angle Grinder For Welding You Should Consider

1. Makita XAG04Z 18V LXT Lithium-Ion Angle Grinder

Among the things that make this angle grinder special is that it’s lightweight. Therefore, people can hold it with one hand and finish the job efficiently. It operates on batteries so there is no need to look for power outlets around you.

Not to mention that it includes wheels for grinding, which are responsible for extending the life of the disk.

However, there are some downsides that users mention. Mainly, they are about the price being a bit high for this model. Also, some of them report that the battery isn’t powerful enough for their needs.

Top Features To Consider When Shopping For Your Next Best Angle Grinder For Welding

Angle grinders are an essential part of the entire welding experience. But going blindly headfirst into buying one isn’t a very smart thing to do. That’s why it’s important to make an informed and efficient decision. To do that, you have to understand some of the key features and factors you should consider before making that final purchase. Take a look at some of them below!

Cost

Besides the needs (which we’ll talk about in a minute), the price tag can significantly influence the buying process. Of course, before embarking on this voyage, you have to have a certain budget in mind. In other words, that means you know how much money you’re willing and ready to spend on an angle grinder for welding.

Experts don’t usually recommend buying very cheap models. That’s because these don’t last long. Additionally, you won’t be able to use it very frequently as the whole build of cheap angle grinders won’t survive such a demanding tempo.

The positive aspect of all of this is that you don’t have to pay a fortune for a super quality machine like this. Some even say that you can purchase a high-end model for more than a hundred bucks. But, a perfectly great model can be found for as much as seventy-five dollars.

Size

Another useful feature in an angle grinder is its size. Naturally, here, we also refer to how small it is as well as its compactness. With that being said, some may think that a smaller grinder won’t be able to satisfy your needs and won’t have a great performance simply because there isn’t plenty of space in it to encompass a ton of features.

On the contrary, smaller grinders are desired and you should try to look for such models. Moreover, some models can be so small that they can easily fit the palm of your hand. With these, the task you have to complete will be done so effortlessly and without strains in your hands and wrists.

Further, smaller grinders will enable you to do your job in tighter spots. And you won’t take too much of the space with your task, leaving the rest to other tasks or users.

While speaking of this, one other size matters, too. We’re speaking of the disc size. Some of the most popular discs have a diameter of around 4.5 inches. They’re light and enable you to work on a wide range of tasks, even in smaller places. On the other hand, some industrial-level jobs may require discs with a diameter of seven or nine inches.

Safety Measures

Working with an angle grinder and with welding, in general, can be dangerous and sometimes life-threatening. That is if you don’t have adequate safety equipment or don’t know the safety instructions.

For the latter, make sure you thoroughly and carefully read these instructions. They’re usually provided in the user manual which is given to you with the purchase. For instance, you should stay away from flammable substances and objects while you’re grinding. That’s because you may easily cause an explosion and we definitely don’t want that.

While discs offer some level of protection, regardless of how minimal it may be, wearing safety gear is a must while grinding. To protect your eyes from any sparks or debris, put on a pair of safety goggles. Also, an apron can protect your body from such harmful aspects of the job. One of the most popular materials for such aprons is leather.

Needs And Uses

As we previously mentioned, the users’ needs and what for they’re going to use the grinder will largely determine how you shop for such a machine. Mainly, when it comes to welding, angle grinders are used before the actual welding commences, for cutting metal, and for cleaning afterward.

It isn’t seldom for the base metal to be covered in some debris that will otherwise disrupt the welding if it isn’t properly cleaned. This may include grease, traces of paint, or other particles of dirt. This is where the grinder comes into play. With it, you can wipe off the debris and clean the metal so that it’s ready for welding.

What’s more, a grinder can also help you cut thinner metals. With a cutting disc, this is possible and practiced by many users. Yes, it may not be as efficient as done with a plasma cutter, but still, the grinder can do the job just fine.

Even after the welding has been finished, you may still need a grinder. Subsequently, the welding may leave slag, which may look untidy and unprofessional. While other techniques for cleaning this exist, few are as successful and efficient as the angle grinder.

Durability

Purchasing an angle grinder for welding is still an investment. And you want it to last as long as possible. The durability feature takes care of this. Especially if you plan on using it frequently, you should be aware that the system will be under pressure. Professional and quality models will be able to withstand that and protect themselves from debris and dust from damaging them. But, cheaper grinders may quickly break down.

Another important aspect here is the warranty period. It’s nice to look for models and brands that offer a longer warranty period. This means that your product will be protected for a longer time and if something happens to it, you know that the original brand will take care of that.

Frequently Asked Questions About The Best Angle Grinder For Welding (FAQ)

Can an angle grinder be utilized to cut wood and similar materials?

Answer: No, angle grinders should never be used for this. Wood and other soft materials fall apart more easily so the grinder can do this to them and ruin them. On the other hand, metal and even stone can be cut with this tool.

How to know if an angle grinder is powerful?

Answer: Usually, the motor power is the one that’s measured. The amperage goes from 6 amps to 10 and even 15 amps in some cases. However, the last one isn’t very common. Still, it’s obvious that the lower amperage results in lower power and understandably this leads to inability to perform some heavy-duty tasks.

Are cordless angle grinders efficient and should people get them?

Answer: As we mentioned earlier, there are brands that produce specifically cordless models. And they are popular on the market. Mainly, this is because they are independent and don’t require a power outlet in order to operate. While sometimes this may affect the power, they are overall nice grinders that should be at least checked out.

Final Words

After reading all of this, it’s clear that finding the best angle grinder for welding takes a bit of research and time. This is because you should be careful about the features the models on the market have. One of the vital ones is power as it dictates the machine’s ability to handle the tasks you need it for. Also, it should be comfortable and not too large to enable the user to carry it around and use it in every space of their home or workshop.
