Before you can change the blade on your corded angle grinder, there are a few things that you’re going to need.

  2. Remove the grinder blade by hand


  • Safety glasses
  • Protective gloves
  • Goggles
  • Respirator
  • Face shield
  • A pair of pliers (optional)

Step 1: Prepare the Angle Grinder

To get started, it’s always essential to make sure that your angle corded grinder is turned off and unplugged. But, while you’re at it, you might as well turn the grinder head over and take out the brush cap.

Step 2: Remove the Blade

Now, to remove the blade from your angle grinder, all you have to do is to press the blade lock button to loosen it and remove the grinder nut at the center of it. That should be enough for you to wiggle/twist off the blade.

To install the new blade, do all of that in reverse. Then, you’re ready to get back to work with your angle grinder.

How to Remove a Broken Clamped Angle Grinder Blade?

The blade on your angular grinder can be pretty tough to remove if it’s broken. And, if you’re brave enough to try, I would suggest replacing the grinder altogether. I have personally had one break-off when trying to remove it, and that was without any pressure or side-load applied. So unless you want this replacement, it’s best to learn how to remove a broken clamp blade.

Step 1:

The first step here is to shut down your grinder and unplug the grinder power cord from the power source; then, place the grinder on a sturdy surface such as a workbench or table. Also, you can wear an anti-static wristband if you have one.

Step 2:

After you have shut down the grinder and have set it on a sturdy surface, wedge the angle grinder in between something solid like a workbench or table with the grinding wheel exposed where your broken blade is located. You can also place an old towel around it to help brace it into place.

Step 3:

Now, wear your safety goggles and gloves if you have them, and wedge the angle grinder into place by pressing on the other side of it with your body.

Step 4:

Once you’ve braced it, then get either an adjustable wrench or adjustable pliers (depending on which type you’re using) and remove the frozen bolt with grease holding down the grinder wheel.

Step 5:

Remove the broken blade and place the new one you have (if it’s a new angle grinder wheel, make sure to install an unclamped blade first). Then, you can re-install the drive bolt and tighten it down all of the way.

And that’s about it. This process lets you quickly learn How to Remove a Broken Clamped Blade on the Angle Grinder.

How often should You change the Angle Grinder Blade?

You should change your angle grinder blade when it’s no longer cutting edge efficiently. It’s a good rule of thumb to change it when you notice that the cuts being made by the new or used blade are taking a long time, and they aren’t as clean as in previous circumstances. If you find yourself having to apply serious pressure to get through the abrasive material, then it’s definitely time to change out the blade.


What do I do if my grinder blade is slipping?

If your grinder’s blade slips on the grinding wheel, then you need to tighten the screw thread where your blade attaches. If this doesn’t fix the problem, then try tightening down the nut that holds the blade in place. Also, check to see if there are any loose or stripped drive bolts.

What if I accidentally broke my blade, or it won’t cut?

If you break your blade, simply replace it with a new one. If you are unable to get all of the broken pieces out of the grinder body, then using pliers is advisable. Just be careful of the grinding discs or anything else that may get in your way.

What can I do if my grinder isn’t sharpening my blades?

First, you should check to see if your blade is already sharp enough to work with the grinder before you sharpen it yourself. Another thing that may be causing the angle grinder to not sharpen correctly is that you’re picking up.
