Best Cordless Angle Grinders for Different Jobs

Depending on the type of work you plan on doing, the suitable type of angle grinder varies. Here are some examples as for what types of angle grinders are best in each occupation and the reasoning behind it:

Woodworking

Pick a lightweight cordless angle grinder with sanding and grinding attachments. One with wood-cutting and carving discs as it will allow for precision work and shaping and detailing your wood projects. This makes your tool suitable for surface preparation, smoothing, and shaping, all three combined!

Construction Work

With construction work, you’ll definitely need a high-performance cordless angle grinder, for example 18V or higher and 5–7-inch discs. You want your tool to be built for cutting, grinding, and polishing tough construction materials like steel, concrete, and stone. It needs to stand the test of time and demanding environment!

Jewelry Making

This type of work requires compact and low-power cordless angle grinder such as 12V or small 18V models, preferably one that comes with precision accessories. This allows you to do fine grinding and polishing for delicate materials.

Automotive Repair

Mid-range cordless angle grinders, like 4.5-inch ones, with variable speed control would be ideal for any automotive work you might have. This type is great when it comes to cutting exhaust pipes, grinding metal parts, and smoothing surfaces in tight spaces, making your job a lot easier.

Masonry Tasks

Masonry tasks call for all the high-power tools and cordless angle grinders are no exception! Choose one with diamond blades, as it will be effective for cutting stone, tiles, and bricks. Additionally, opt for models with high RPMs.

DIY Projects or home improvement tasks

If you do any DIY work around the house or your workshop, a versatile cordless angle grinder with variable speed and accessory compatibility is your best way to go. This type of angle grinder makes it easy for you to take on different light-duty tasks like cutting, sanding, and grinding without the need to whip out another tool!

Best Cordless Angle Grinders: Basic Vs Premium

Finding the best cordless angle grinder depends on many criteria, like the type of work you plan to do with it. However, two of these factors are the blueprint: always the same, no matter the project!

1. Power and Performance

What’s the most basic criterion you require your angle grinder to provide? That’s right! It’s sufficient power and performance. That’s why you need to look closely to find one that wouldn’t underperform.

Make sure you find a top cordless angle grinder that has a brushless motor. Brushless motors are highly efficient, durable, and powerful, with less heat generation and quieter operation. They offer precise control, longer lifespans, and lower energy consumption. All of this makes it a must if you want the best of the best!

Moreover, make sure you check the RPM (rotations per minute) as it will be the one feature that’s capable of giving you the gift of time and energy: the higher the RPM, the faster the cutting and grinding!

2. Battery Life

The last thing you want is to start to get all caught up in your work and then the battery dies! The best cordless angle grinders offer lithium-ion batteries, as there is a huge gap between these batteries and the older generations in performance and longevity.

Most of the top–rated cordless angle grinders do come with one or two extra batteries, just to not let the tool leave you high and dry in the middle of a project!
