What Is an Angle Grinder?

The way an angle grinder works is simple. Each one is equipped with a switch or a trigger, which engages the tool’s power source. Once the grinder is powered on, the gears inside of it turn the tool’s 90-degree-angled head to spin the wheel. To control its movements, hold the body with one hand and the side handle with the other.

How Are These Tools Powered?

Angle grinders are available in several setups. Some run on compressed air while others require gasoline. It’s common to find compressed air angle grinders in places like body shops because they usually have an air compressor on site. On the other hand, gasoline-powered angle grinders are better suited for outdoor projects such as those that involve masonry.

There are also angle grinders that are powered by an electric motor, which may be corded or cordless depending on the model. These tools are great for a wide range of uses, and they are perfect for the weekend DIYer.

Should I Buy a Corded or Cordless Angle Grinder?

Choosing between a corded and a cordless angle grinder is a difficult decision since both have their own merits. With a corded model, you don’t have to worry about the battery lasting throughout your project, which is sometimes a real issue due to frequent starts and their accompanying power surges.

A power cord on any tool is an instant trip hazard, especially if your project necessitates a lot of walking, and a cord puts a limit on your working range. If you do decide to go the battery route, make sure you purchase a spare, so you won’t have to wait while the battery recharges.

What Safety Measures Should I Take Into Consideration?

Even though angle grinders are not hard to operate, don’t let their user-friendly nature let your guard down when it comes to safety. Wear safety goggles to prevent stray metal particles from lodging in your eyes and heavy-duty gloves to reduce the likelihood of cuts. You should also don a dust mask and ventilate the work area.

Before you power on an angle grinder, make a firm grip in preparation for kickbacks. If it’s your first time using an angle grinder or you’re breaking in a new one, start at a low speed and work upward from there in order to get comfortable with the tool.

Also, be sure to use an intact disc with a maximum speed that surpasses that of the grinder. Otherwise, you risk causing the disc to overheat and subsequently shatter.

How Much Maintenance Does an Angle Grinder Require?

Typically, angle grinders are low-maintenance power tools. To keep yours in working order, remove all the dust and debris from the grinder after each work session. If the angle grinder is of the corded variety, check the tool’s power cord periodically for any damage.

An angle grinder is not a tool that you should purchase blindly. To get one that gives you the best and most reliable performance possible, you need to know how to pick out a high-quality model. If you are shopping for an angle grinder and feel overwhelmed by the plethora of choices on the market, this guide can point you in the right direction.

The Motor

Since the motor determines the angle grinder’s power and speed, always look at this feature first. Depending on the manufacturer and the model, you may see a rating for horsepower, amps or both. To get sufficient power, you need a grinder with at least a 6-amp motor.

Also, pay attention to the angle grinder’s rpm, or revolutions per minute. Often, small grinders are faster than large ones. While the grinder’s speed may not be important for every job, a fast one can reduce the time it takes to complete a project.

Wheel Size

If you need an angle grinder for big-time projects, a wheel size of 9 inches is ideal. However, 4.5-inch-wide grinders are more suitable for at-home use, and these grinders are not as difficult to control. To make disc changes less time consuming, many models have a spindle that locks.

The Side Handle

Every angle grinder has a side handle. However, not all of them are comfortable. To get the best grip possible, you’ll want the handle to be slim and textured. Many models allow you to change the position of the handle’s tilt to maximize your comfort. There are even angle grinders with a handle that you can attach to the left or the right of the tool to accommodate your dominant hand.

Weight

The tool’s weight also determines its usability. Obviously, you don’t want the angle grinder to be bulky, especially if you’re only using it for weekend projects. However, a grinder that’s too light won’t outlast tough use year after year. Therefore, stick to an angle grinder that weighs at least 3 pounds but no more than 10 pounds.

Safety

Power tool manufacturers generally put a great deal of their attention toward safety features. At a bare minimum, the angle grinder you choose should be equipped with a durable guard, which may or may not require a tool to adjust. For added safety, some manufacturers design the power switch to lock, so you won’t start it up accidentally.

Materials

Before you pull out your wallet, examine the materials used to build the angle grinder’s housing and gears. Ideally, these components should be constructed from metal. However, you can still get by with a grinder that has gears made of plastic or nylon if you don’t plan to use the tool frequently.

Dust Protection

Dust is the Achilles heel of all appliances, power tools and electronic devices. Any angle grinder that addresses this problem is worth your consideration. In order to ensure that dirt and dust stay away from the tool’s motor and gears, many angle grinders are built in a way that seals the motor from destructive dust.

There are also some angle grinders that are equipped with technology that expels these particles, so they can’t settle inside of the tool and accumulate over time.
