Things You Should Consider Before Purchasing the Best 7-Inch Angle Grinder for Concrete
A great instrument for grinding, sharpening, polishing, and cutting surfaces is a grinder. For their household works, general users typically use angle grinders in the 4.5 inches or 5 inches size, while professionals and specialists typically utilize a 7 inches angle grinder. If you do some research, you will discover that a lot of 7 inches grinders are available out there on the market.
It will be simple for you to question the ideal types of grinders that you should use. Don’t get worried! We will assist you in making the right decision. Before purchasing anything, there are a few things to consider, and grinders are no different.
Here, we will only cover the essential criteria you need to consider before buying a 7-inch angle grinder. Therefore, grab a pen and note the below-mentioned things:
Think about the Power Type
You have to first choose the power type that best meets your needs. The two most popular types among customers are typically corded and cordless. Both of them have unique features and specifications. In essence, corded ones typically give higher torque and power, whereas cordless ones can be used nearly anywhere.
Power of the Grinder’s Motor
To effectively grind your concrete floors, you will need a high-quality motor. The equation is simple, the more horsepower your angle grinder’s motor has, the more efficient it will be. You should therefore choose an angle grinder with a high motor power rating.
Safety Features
When utilizing anything that you can’t ever leave, safety is critical. The angle grinder you wish to buy should contain at least a few safety features, which most of you miss and end up with small to big damages every year. Let’s quickly review the three most important safety features below:
Thermal Overload: This feature is needed to prevent your angle grinder from overheating on its own.
Automatic Shut-Off: It enables your angle grinder to immediately shut down the motor if it overheats or needs new grinding wheels.
Spindle-lock Switch: This feature assists you in replacing wheels by locking, which ensures a secure wheel adjustment.
Keep in mind that whether your angle grinder contains safety features or not, it is still a good idea to put on safety gear before doing any operations, such as gloves, goggles, face masks, and boots.
Speed
Typically, we enjoy dynamic things. However, going too fast isn’t always a smart idea. Too much speed might break the disc on larger wheels. In addition, too much speed can occasionally cause the angle grinder to overheat and possibly get destroyed. For this reason, you should purchase a medium-speed power tool that will not become excessively hot while working.
Build Quality
A cheap plastic model will only leave you disappointed. So, choose an angle grinder that is constructed of alloy steel or some other hefty metals if you want something that will be durable and last for a very long time. However, if the plastic seems strong and resilient enough to endure severe torture, it is completely OK.
Comfortable to Use
If you are looking for comfort, two things are important, which are a soft gripping area and a lightweight design. Therefore, it makes sense to spend your money on a power tool that contains any of them and will enable you to work without feeling tired even after a long period. It is important to remember that using a smaller angle grinder is more comfortable than using a larger one.
However, it’s best to utilize large grinders if you are an expert and have a challenging task at home. You will find some angle grinders that feature vibrating handles, which are exceptionally comfortable for any task. Also, you will find some small angle grinders that are simple to maintain for an extended period.
Moreover, having a model with a low-profile design is advantageous. If so, it will make it as easy as possible to get into confined spaces during concrete grinding. Finally, we can say, invest in the power tool that gives you the most comfort.
Price
It will be difficult for you to purchase a grinder if you are a newbie. As you don’t have enough idea about grinders’ prices, you have to conduct some research before making a purchase. Find out more about this, decide on a price, and then pick the best grinder you can afford.
Keep in mind that you should take caution when making purchases or you may waste all of your money. In the above guide, we have covered some purchasing tips for your convenience. If you can properly follow these purchasing tips, then it will be easy for you to purchase the perfect 7-inch angle grinder for your concrete grinding projects.
Final Words
Nothing is more dependable and superior when it comes to sanding concrete than a high-quality angle grinder. With a 7-inch angle grinder, you can effectively complete various other tasks as well. It might be difficult to decide which 7-inch angle grinder is the best because there are lots of brands and different angle grinder models to select from.
