Buyer’s Guide 7-Inch Angle Grinder
A 7″ angle grinder has become popular because it combines high performance and compact design perfectly. There is a wide selection of these tools, and it is hard to focus on anything. Especially if you are buying this kind of tool for the first time, you might be tempted by the low price or the loud name, but you will need some essential details. In this section, I will tell you what parameters to pay attention to buy a worthy thing.
Motor power is the first thing you should consider when buying any electric tool. The harder work you plan to do, the more powerful the motor should be. Most 7″ angle grinders have a pretty potent 15-amp motor. This power is enough to grind concrete, cut tile, and any stones. The 7-inch line of grinders also has super productive units with a 17,5-amp motor.
Size and weight
These criteria directly affect your productivity. After all, you can’t talk about a quality job if you can barely hold a tool in your hands after half an hour. You should be able to keep the grinder comfortably, even when working in hard-to-reach areas. Look for models with an ergonomic design and a handle that will fit your hand size. As for weight, 7-inch angle grinders can weigh 8 pounds or more.
7-inch angle grinders can be corded or cordless. Cordless models run on battery power and are attractive because of their mobility. You can work anywhere, even if there is no power source nearby. But cordless models tend to be more powerful and provide better torque.
To protect yourself from injury, follow the safety rules. Choose an angle grinder with at least basic safety features. For example, it could be an auto shut-off when the tool overheats or needs a part replacement. Having overheating and overvoltage protection will also be a significant advantage. A start button lock will keep you from accidentally turning the tool on while you’re replacing parts, and so on.
For example, 7-inch angle grinders are not as fast as 4-inch grinders. But their advantages are that they are still fast due to the larger disc size. The 7-inch unit has a speed range of 6,000 to 8,500 RPM. That is because the high speed of a large wheel puts unnecessary stress on the motor. Therefore, the device may malfunction during operation.
