This section will help you go about your purchase without hassle. Here are some vital points you should consider before buying an angle grinder:

Types of Angle Grinders

Knowing the different types of angle grinders out there will help you make only the right choices.

1. Corded angle grinders

Corded angle grinders are the type you need to plug continuously into a power source before working. The benefit of using corded angle grinders is that you get consistent and indefinite running time. Also, they usually weigh less than the cordless models and are also cheaper.

The biggest challenge with using this type of grinder is that you need to be within a good range of a power outlet.

2. Cordless angle grinders

Battery-powered or cordless angle grinders work with their power. This type of grinder is perfect for jobs that require having a grinder on scaffolding or a ladder. These days, you will find modern brushless electric motors which last a long time between recharges. When charging this device, expect to use a minimum of half an hour to get the needed charge level on a drained 6Ah battery.

3. Pneumatic angle grinders

This type of angle grinder is an upgrade to the electric angle grinder. To use them, you need to get them plugged into a suitable air compressor unit to work effectively. Since they don't come with electric motors and batteries, they work using air pressure. They also rank as one of the cheapest options out there.

Tips for Choosing the Best Angle Grinder

Before you buy angle grinders, there are a few things you need to consider. Here is a breakdown of some of the critical factors to consider:

Speed

Whenever you compare the speed between the different angle grinder models, you need to keep it at the back of your mind that those who can take smaller discs can produce quicker RPMs than the larger ones. The RPM talks about the quickest rotation that can be done without installing a disc.

Large angle grinders usually come with a slower pace of about 6,000 RPM, while the medium angle grinders come with a faster than 8,000.

Size

There are different size options of angle grinders, ranging between 9 inches and 4 inches. Also, you may find something that measures smaller or a bit larger. Note that a 4-inch angle grinder is the most affordable and works for many purposes. On the other hand, a five-inch angle grinder is reputed to be suitable for cutting through tubing more quickly than the 4-inch option. The 9-inch angle grinder is reputed to be perfect for heavier materials such as concrete and steel.

Power

In the power department, you need a built system with enough power to help you get the work done. The majority of systems are built with 2,500 watts and 500 watts, even though you may find those with power ratings that are lower or higher. What this implies is that you may get between 4 to 15 amps.

Wheels

Chances are, you will get more than one wheel with the angle grinder. You may never know where and what you will need your angle grinder to do at some point. For instance, you may use an angle grinder to brush off some primer from the walls at some point or even sand your wood before staining it. At other times, you'll only be using it to cut through wood/metal. 

Handle

It would help if you also had an ergonomic, non-slip handle that you can quickly move around. An angle grinder can is a dangerous tool and may cause serious harm if used with recklessness. So, make sure you're investing in the right tool!

What Are the Different Uses of an Angle Grinder?

Angle grinders were initially made for abrasive discs, although their popularity and versatility have made more manufacturers use them for other purposes.

• Grinding is the foremost reason why people buy and use grinders. If you get the correct type of grinding wheel, you can use your angle grinder to grind down sharp corners, metal weld lumps, and the likes.
• Surface preparation and sanding is one of the most common uses of an angle grinder. If you combine it with the right sanding pad, angle grinders can prove to be very effective for removing old paints and handling other defects.
• Another area where the angle grinder is functional is in cutting if the correct cutting disc is installed. Different cutting attachments will allow you to cut through tile, masonry, metal and concrete, and softer stuff such as wood, plastic, and PVC.

Safety Tips While Using Angle Grinders

The motor of an angle grinder can run at high speeds of up to 11,000 rpm, which ranks higher than drill motors. Take note of the following safety precautions while using the grinder:

• It's important that you read the manual well if you are using the machine for the first time.
• Make sure you use the proper safety gloves, eye protection, and shoes to avoid accidents.
• Always keep away from bystanders.
