The Best Angle Grinder Choice for 2018 – Tested & Reviewed

Whether you are trying to cut through metal or masonry, remove burrs and rust, or simply cleaning up metal work, an angle grinder is an integral part of your toolchest. Outside of well-informed professionals, however, there is a sort of epidemic of users buying poorly crafted cheap grinders that clutter the store shelves.

Best Angle Grinder

An angle grinder is one of those tools that will likely be looking at a hard life—they are commonly at the forefront of tough and time-consuming tasks, and the less durable/low-cost modelsare prone to giving out relatively quickly. Cutting and brushing tiles, concrete, and metal requires a large amount of power, and pieces can quickly break or wear down.

There are a number of durable angle grinder options out there, but the generally higher costs of those tools often make buyers hesitant to make the purchase. The truth is that buying the right angle grinder, one made to get the job done quickly and built to last, can actually be a money saver. To that end, we have put together a list of some of the best angle grinders out there—these are all solid tools worthy of their investment, and will likely last 5x or so longer than the bargain bin angle grinders.

This is another cordless grinder with the power to take on the tougher jobs in a service garage or auto body repair shop, as well as tile, stone, and concrete cutting.

Another cordless angle grinder with a brushless motor, the Makita XAG03Z is an excellent addition to the lineup of affordable yet high-end brushless grinders we have been featuring at the top of this list. This Makita uses additions like the automatic speed changing and a compact design to stake its niche out.
