After securing the spindle lock, use the wrench to carefully loosen the locking nut by turning it counterclockwise. Depending on the model of your angle grinder, this may require some effort, especially if the nut has not been removed for a while. Once loosened, you can remove the nut completely.
Once the nut is removed, you can carefully slide the existing blade off of the spindle. If the blade seems stuck, gently tap it with a rubber mallet to loosen it. Be cautious during this step to avoid injury, particularly from the sharp edges of the blade.
What type of blade should I use for my Dewalt angle grinder?
When selecting a blade for your Dewalt angle grinder, it is essential to choose one that is compatible with your specific model and intended use. Dewalt offers a variety of blades, including cutting, grinding, and polishing discs, for different materials such as metal, concrete, and wood. Consult the user manual for detailed recommendations on the best blade types for your projects.
Additionally, consider the diameter of the blade that matches your angle grinder specifications. Most Dewalt angle grinders will accept blades that are 4.5 or 5 inches in diameter, but always verify your model’s requirements.

If the blade becomes stuck during removal, do not force it as this could damage the grinder or result in injury. Instead, check to ensure that the spindle lock is engaged properly. Sometimes, the blade can be slightly rusted or dirty, causing it to bind on the spindle. A soft application of penetrating oil around the spindle can help in this scenario.
After applying the oil, let it sit for a few minutes to penetrate the rust. Then, again attempt to remove the blade using the correct technique. If it still does not budge, consider consulting a professional or referring to the manual for specific troubleshooting steps related to your Dewalt model.
How do I properly install a new blade?

Most blades have an arrow indicating the cutting direction, and it is vital to align this arrow with the rotation direction marked on the angle grinder.
Once the blade is in place, reattach the locking nut and hand-tighten it initially. Then, while securing the spindle lock, use the appropriate wrench to tighten the nut fully. Make sure it’s secure, but avoid over-tightening, as this can lead to damage or warping of the blade. After installation, you can plug in your grinder and perform a brief test run before commencing your work.
How often should I change the blade on my Dewalt angle grinder?
The frequency with which you should change the blade on your Dewalt angle grinder largely depends on the type of work you are doing and the materials you are cutting or grinding.
