Angle Grinder Buying Guide

Anyone who has ever had to grind metal, rout mortar or cut tile has probably used an angle grinder for the job. That’s precisely the kind of jobs that these tools were designed to do, along with polishing and sharpening metal as another common use for these tools. And there are dozens of these grinders available online or anywhere else where power tools are sold. So many that it can be difficult for a person to find the one that fits their needs. That’s why we’ve decided to write this little guide on angle grinders. In this guide, we hope to show all of our readers just what they should be looking for when they buy a new angle grinder.

Step One: Consider The Grinder’s Size

One of the very first considerations the DIY enthusiast or professional is going to want to consider is the size of the angle grinder they are going to need. Although these grinders seemingly come in a thousand different styles, most of these can be placed into one of two categories: grinders that are either larger than 7-inches in size or grinders that are smaller than 7-inches in size. Ones that are under 7-inches are referred to as small angle grinders and ones 7-inches or larger are large angle grinders. Small-angle grinders are usually about 4.5-inches in size and are good for DIY projects. Large angle grinders, on the other hand, are designed for professional use.

Step Two: Decide On A Corded Or Cordless Model

Angle grinders can also be divided into two other categories: cordless or corded models. And that’s something that a person should give careful consideration to before they decide upon one or the other. That’s because both corded and cordless angle grinders have their merits and their drawbacks. For example, cordless models can be taken anywhere, even off-grid if necessary because they’re powered by a battery. Unfortunately, this also means that the grinder probably doesn’t have as much power as a corded model, and the operator is going to have to change out batteries frequently. Corded models have a lot of power, and can operate as long as there’s power coursing through an electrical outlet, but they can’t be taken off-grid (at least not without bringing your generator or another power source), and there’s also a pesky cord that limits how far it can be used from an outlet.

Step Three: Consider Whether You Want Variable Speed Control

Okay, we’re going to go out on a ledge and say that you’re probably going to want to buy an angle grinder with variable speed control. What’s variable speed control, you ask? This feature allows the operator to control the speed of the spinning disc. This is quite a useful feature for these tools to have. That’s because you can operate it at full-speed for tough grinding jobs, but you can also back off the speed for jobs that require a slower speed, such as polishing. This allows the user to control the heat build-up on the surface being ground or polished for better results.

Step Four: Consider A Trigger-Lock And Adjustable Handle

Another thing to think about before buying a new angle grinder is what kind of features does it have that makes it easier to handle. Two of the main features that make using an angle grinder easier are the trigger lock and an adjustable handle. The trigger lock enables the tool to be locked in the on position so that you don’t have to keep constant pressure on the trigger during use. An adjustable handle makes it easy to adjust to the size of the operator’s hand and for when they’re going from one-hand use to two-hand use. Both of these features make these angle grinders more ergonomic to use.

Step Five: Consider The Grinder’s Motor

The last thing to consider before acquiring your new angle grinder is to consider the motor size of the tool. Although there are angle grinders that come with all size motors, the ones that are the most powerful are the ones in the 7-amp or larger range. That’s the motor size that’s necessary for professional jobs. On the other hand, if you only need the grinder to do DIY projects, then you probably don’t need a professional angle grinder. In that instance, you can choose a model that has a 4.5-amp or 5-amp motor. Those models should be powerful enough for most DIY jobs.

Other Features To Think About
