Its specifications are similar to the DWE43144 model, but this model is pricier than the other Dewalt grinder.

Complete Buying Buying Guide of Best 6 Inch Angle Grinder

If you’re looking to buy an angle grinder, there are a few things that you should note down first. First, identify the operations that you’re going to use the tool for after which comes the machine’s specifications that you are going to use for the identified operations. Then comes user comfort. Suppose your tool is always keeping you at an edge, and you’re always getting stressed out at a faster than usual rate. In that case, the tool is uncomfortable, and the result is you being unable to work for longer periods with your power tool.

You should consider the following things when buying an angle grinder-

Usage: Angle grinders are mostly used for cutting, polishing, and sanding metals, tiles, stones, and pavers. The versatile tool is also used to clean metals, cut metal bars and rods, and shape the cutting edges of a metal part. So you’re going to have to outline where and how you will use the power tool.

Wattage: The next thing you should consider is the wattage. The more wattage your power tool has, the better power your grinder will deliver.

Speed control: After that, you should want to have a variable speed controller in your power grinder. If you can control the speed of your machine, you’ll have more precision in your work.

Handlebar: Handlebar is another aspect that you should focus on. If you are a left-handed operator, then you’re going to have to use one with a left-handed bar, and if you are a right-handed operator, then you’re going to have to use one with a right-handed bar. Your considerations here should be a grinder with adjustable handlebars. One other thing to consider in a handlebar should be anti-vibration protection features to eliminate unnecessary stress on your arms.

Safety features: It is one of the biggest aspects of consideration when buying the power tool. Angle grinders have many risks involved, with the kickback momentum being the deadliest of them all. To protect yourself from all the possible threats, you’re going to need a bunch of safety features like the anti-kickback, quick wheel brake, and safety clutches in your power tool.

Mobility: Mobility is another aspect operators should consider for easier workflow. A cordless angle grinder naturally has more mobility than a corded model. 

Price: The last aspect to consider should be the price. You have to figure out which angle grinder has the best features at the lowest price, so you don’t waste money on more expensive grinders with fewer features.

Angle Grinder Safety Instructions:

Grinders are as dangerous as it is useful. Without proper safety precautions, operating the tool can be equally threatening as a chainsaw. The discs of this machine can shatter and destroy a part of the body in a kickback event, potentially causing a fatality.  

What safety precautions should you follow?

  • Different grinders come at different speeds. Check the manufacturer-provided manual to be sure about the speed of the tool you will be operating with.
  • When purchasing a grinder, choose one with adjustable handlebars that can move to suit both left and right-handed operators.
  • Follow the manufacturer’s manual for instructions on how to operate the machine safely.
  • There are few components available as safety measures against the tool. Try to equip all available safety equipment at your arsenal before heading to work. 
  • Do not use the tool on wet floors.
  • Make sure to clean the surfaces surrounding the work area. 
  • Ensure that everything in the machine is working fine before operation.
  • Use welding screens to stop other workers from getting hit by flying particles.
  • Ensure all workers maintain a safe distance from any person who is grinding.

How to Use an Angle Grinder

An angle grinder can come in handy in making a lot of construction and maintenance works easier. If you know your way around with the tool, it can be one of the most versatile tools you can have in your arsenal. As we have stated earlier in this list, angle grinders are used for tasks like cutting, polishing, sanding metals, tiles, stones, pavers, etc. However, it is not a tool that everyone can handle without proper knowledge and training.

Get to Know Your Power Tool

To start working with the machine, you’ll have to get to know it first. You must know when and where these tools are needed and how to use them. Assuming you already know where to use these machines, you’ll now have to know how to use them.

Open the user manual provided by the manufacturer of your power tool when you first bought it. It will probably still be in the product’s packaging if you haven’t used it. Open the manual and thoroughly go over it to know the functionalities and features of your grinder. The user manual will also have instructions on how to use the tool, so you’ll get used to it better.

Angle Grinder Safety

You now know how to use an angle grinder, and it’s time for you to throttle your power tool. Before you go into action, you have to protect yourself from your power tool. The grinder is equally as hazardous as it is useful in your tasks.  

A grinder is a noisy tool that could create loud sounds. It is also a tool that keeps throwing debris all around while working. The tool is also prone to frequent kickbacks. To protect yourself from all those dangers, you’ll have to equip a set of gear. You should try to have ear, eye and face protection and cut-resistant gloves, boots, and a PPE in your protection equipment.

Positioning the Tool Properly

Since angle grinders slice materials faster by grinding the disc against them, it can produce a good amount of recoil that can cause kickback. To lower the risks of kickback momentum, position the tool in a comfortable way where you can utilize the best of your physical strength to hold it still until the work is done.

Keep Those Sparks Away

When angle grinder discs are grinding against a material, it produces tons of flaming sparks. Although not thick enough to cause even a tickle, exposure to the flaming sparks for a long period of time can leave burns on your skin. Position your machine in a way where you can keep those sparks away to the opposite side of your body.

Preparing the Workplace

Finally, before you start doing any kind of task with the power tool, you should always prepare your workplace for a safe operation.

Start by cleaning the workplace and the area surrounding it. Since angle grinders create a lot of debris and flying particles, you’re going to have to move anything that you don’t want to be covered in dust away from the workplace.

Look for anything combustible around your workplace. If you find any, keep those materials out of the workplace. As we said earlier, the flaming sparks can leave burn marks on your body, and these particles can also burn anything that is combustible. Beware of that.

Try to let the debris fall downwards while operating. Although you won’t completely be able to, it will reduce the amount of debris flying all around in your workplace and the number of things they will cover.
