Things to Consider When Buying the Best 7-Inch Angle Grinder for Concrete

Still, having doubts about the best angle grinder for concrete? Well, many people get overwhelmed after looking at so many features and specs. If you’re one of those, then this buyer’s guide will really come in handy!

Here, I’ll incorporate only the core factors that you must look for prior to making your buying decision. So take a pen and keep the below-mentioned things noted:

1. Consider the Power Type

At first, you need to determine which power type suits your requirements best. Generally, corded and cordless are the two common types among customers. Each of them has its own specs and qualities. But in a nutshell, corded ones offer more torque and power in most cases, while the cordless one can be used anywhere.

2. Power

A high-quality motor and higher RPM is a perfect combination of power that you’ll need to grind your concrete floors quite effectively. The motor horsepower your motor has, the better it’ll perform; and the same thing goes to the rate of RPM, so there is no rocket science!

Another thing is pretty related to power; yep, I’m talking about the speed. The best 7-inch angle grinder should run so quickly so that you can complete your task within a shorter period.

3. Build Quality

A low-end plastic model can give you nothing but disappointment. So if you want to get your angle grinder long-lasting and durable, go for something that’s made of alloy steel or other heavy metals. But it’s absolutely okay if the plastic appears sturdy and able to withstand heavy torture.

4. Comfortable

As for comfort, two things come together; lightweight design and soft gripping area. So it makes sense that you spend your bucks on an angle grinder that gets any of them, for which you can ensure a fatigue-free operation even after working for too long!

Besides, having a model that features a low-profile design is a plus. If yes, you can get the maximum convenience in accessing tight areas during concrete grinding.

5. Safety Features

Last but certainly not least, the model you want to purchase should at least have a couple of safety features, which the majority of you overlook and end up with minor-to-major damages every single year. Let’s have a look at the 3 essential safety features at a glance:

  • Automatic Shut-Off: If your power tool gets overheated or requires replacing the grinding wheels, the motor shuts off straight away with the help of this feature.
  • Thermal Overload: It itself keeps your angle grinder away from getting overheated.
  • Spindle-lock Switch: Helps you replace wheels by locking, ensuring a safe wheel adjustment.

Note: It doesn’t matter whether your power tool has safety features or not; putting on safety gear before any operation is a wise idea, like gloves, face masks, boots, and goggles.

The Final Verdict!

When you think about sanding concrete, there is nothing more reliable and better than a top-quality angle grinder. And this is what I did; I’ve added the best 7-inch angle grinder for concrete in this review post, for which you can find out your best match, depending on your budget and overall requirements.
