How to remove bench grinder wheel: The easiest way to remove your grinding wheel is to use a wrench to loosen the bolt, pull the wheel off and replace it with the next one. If you can change a drill bit, you should be able to do this task as well. It just takes a little longer.
As easy as it sounds, changing a grinding wheel is not without its nuances. You will run into some unique situations that will leave you scratching your head. In the following article, we will address those nuances as well as give you step-by-step directions on how to change a grinding wheel.

Here are the steps:
Every once in awhile, you will come across a situation where your grinding wheel gets stuck. One of the more common reasons is you haven’t used your bench grinder in a long time and the nut, bolt, washer rusted and now the wheel is not going to come off.
When this takes place, you are going to need to follow some of the steps listed above. But after you unplugged the bench grinder and before you start removing guards and the tool rest, spray some WD 40, penetrating oil or similar rust-fighting compound on your nuts, bolts, and washers.
Then you can start removing the guards, etc. You need to give those compounds time to work. After you got the extra parts off, there are several methods you can try if the penetrating compounds do not do the trick:
The tool you use depends a lot on what type of grinder you are working on and how the wheel is attached to the bench grinder. The most common tools you will need are a wrench, screwdriver, possibly some lubricating oil.
Due to some of the nuances that come with bench grinders, it might be a wise choice to wear the appropriate gloves. There will be times that you will have to hold on to the wheel on the other end of the grinder so you can loosen the nut quickly.
It is not that grinding wheels are extremely sharp, though they can be, it is that they are very abrasive and may hurt your hand when you hold them. Also, you may want to wear safety glasses just in case the wheel breaks or chips and the pieces start flying.
The only time you are going to need more tools than the ones described here is when the wheel gets stuck and you need extra help getting it off.
In our research, we found no instructions or guides that showed how to remove a grinder wheel without a tool. There are a lot of reasons for this. One, there are just too many screws, guards, and other accessories in the way.
Two, the nuts, screws, and washers, etc. Are just too tight for hand twisting. If your hardware is that loose, then you should have been experiencing some difficulty with your grinding wheel and bench grinder.
Once you get all the extra equipment off your bench grinder and remove the washer and nut you won’t need a tool to slide the grinding wheel off. What you will need, if it applies, is a little WD-40, penetrating oil or lubricating oil to make the wheel slide easier as you pull.
When you pull on the grinding wheel, you should use gloves or wrap a cloth or a rag around the wheel to keep your hands protected. Then reverse the process when you need to put the wheel back on again.

We have produced this list before but it bears repeating because there are some risks involved when you use the wrong metal on the wrong grinding wheel. We want to make sure you understand that grinding wheels are not universal.
For example, if you use aluminum on a grinding wheel made for steel, you run the chance of clogging up the wheel and rendering it useless. You may also spend a long time cleaning the wheel.
Two potential risks you run into when you use the wrong material on the wrong grinding wheel is that the wheel may crack, break or not grind. The other risk is that it may explode and sending pieces of the wheel everywhere.
Also, you may not see any danger when you use aluminum but that is normal. It is the next person in line that is exposed to the risk. So you have to be careful and use the right materials with the correct grinding wheel.
Here is a list of wheels and the metals you can use on them.
