Here’s a step-by-step guide to help you out:
Before you start, always put your safety first. Wear protective gear, including work gloves, safety glasses, and a dust mask. Unplug the grinder from its power source before you start replacing the blade. This will ensure no accidents occur during the process. You should also check that the blade is compatible with your angle grinder.
Prepare the grinder
Now, get the grinder ready to replace the blade. Unscrew the locking nut and washer on your angle grinder to release the blade from its position. Then, remove and discard the flange, as this part will not be reused. This will expose the blade and make it easier to remove. You can then pull the blade off from its housing.

Next, you can change angle grinder blade. Ensure the blade is compatible with your power tool and that all safety precautions have been taken. Ensure the correct side of the blade is facing outwards. Now secure the blade with a washer and hand-tighten the locking nut. The washer should fit tightly against the blade, while the locking nut should be secure yet easy to remove with a wrench.
Reinstall the new blade
Once you have secured the new blade in place, it’s time to reinstall it. Place the flange on top of your angle grinder and ensure it fits snugly. This will help hold the blade in place to ensure it runs efficiently and safely. You can then reinstall the washer and locking nut to finish the process.
Test the grinder
The last step is to test your newly changed angle grinder blade. Plug in your power tool and turn it on, ensuring all safety measures are in place. Then, test the blade to see if it is working as expected. If you find any issues, you may need to tighten or loosen the locking nut accordingly.

How to Choose the Right Angle Grinder Blade?
Now that you know how to change the blade in an angle grinder, let’s look at how to choose the right one. The type of blade you use will depend on the material and project you are working on. Here are some tips to help you select the perfect blade for your angle grinder:
Choose the right size
The first step is to choose the right blade size for your angle grinder. Measure the diameter of your power tool and then find a blade that matches. This will ensure it fits securely on the grinder and won’t fall off during use. The blades come in various sizes, such as 4.5-inch, 7-inch, 9-inch, and more. The grinders usually indicate the size of blade you need in their instruction manual.
Consider your material
The type of material you are working with will also determine the kind of blade you need. Different blades are designed for different materials, so select the appropriate one. For example, metal cutting blades can handle hard metals like steel, while abrasive cutting blades are better for softer wood or plastic.
Pay attention to the teeth
The number of teeth on the blade will also make a difference. Blades with fewer teeth are better for faster cuts, while those with more teeth give you more control over your work. So be sure to choose the type that suits your project best.
When selecting an angle grinder blade, look for safety features such as anti-kickback teeth and vibration dampeners. These features reduce the risk of accidents or injury while using your power tool.
Finally, don’t forget to check the quality of the blade. Look for blades made from high-quality materials such as tungsten or diamond-coated steel. These blades are designed to last longer and provide better results than regular steel blades.
Knowing how to choose the right angle grinder blade is essential for ensuring the efficiency of your power tool.
