How To Balance Bench Grinder Wheels | 4 Quick And Easy Steps

Bench grinder wheels can quickly become clogged with debris, which can lead to poor performance and eventually damage to the machine. We’ll teach you how to balance bench grinder wheels to ensure optimal performance and long-term durability. There are tips on how to prevent debris from becoming clogged in the first place, so you can keep your machine running smoothly for years to come.

Bench Grinder Wheel

A bench grinder wheel is a circular grinding wheel that sits on the arm of a bench grinder. Bench grinders are used for sharpening blades(blade edge), cutting chips(blade angle), and other various tasks in woodworking.

Bench grinder wheels are round because they typically rotate at high speeds around the tool rest while grinding stone, ceramic material, wood, or metal parts. The spinning action loosens material from the object you’re trying to sharpen or cut so it can be reduced down to finer pieces by the teeth on the wheel.

This is like an angle grinder but it is fixed with the workbench that’s why it is called a stationary grinder.

Why Bench Grinder’s Wheels Are Unbalance?

Bench grinder wheels can quickly become unbalanced grinding wheels because of the nature of the wheel. The wheel consists of several sharp, curved blades that cut into the material being ground. As these blades move around on the wheel, they generate a lot of friction and heat. This heat is also what causes metal to flow along certain areas of the blade more than others.

This uneven distribution of metal can cause one side or edge on a bench grinder wheel to become thicker and heavier than the other side-resulting in an imbalance. Over time this imbalance will cause additional wear on your machine and can eventually lead to wheel failure.

Required Material and Tools

To balance a bench grinder wheel, you’ll need the following items:

  • Bench grinder wheel.
  • Balancing kit if you have one.
  • Spindle arbor or shaft (if applicable).
  • Hex key set (or Allen wrench if using an arbor).
  • Level or straight edge of some sort.

Once you’ve gathered these materials, proceed to the following steps:

  • Step 1. Remove the spindle from the machine if it’s attached. If not, loosen the bolt that holds it on with your hex key and remove it.
  • Step 2. Place your level on one side of the wheel and hold the wheel in the same position while turning the spindle on the balancing arbor. Keep it as level as possible and make sure that both edges of the wheel are lined up with the center of your mark.
  • Step 3. Replace the spindle on your machine, tighten the bolt down, and test wheel balance by grinding a small amount of material off one side of an object using a medium or high-speed setting. If necessary, adjust wheel balancing screws accordingly until you’re happy with the results.
  • Step 4: Repeat steps 2-3 for another side of the bench grinder wheel. Now your grinding wheel is properly balanced wheel and balanced position and will no longer cause uneven wear on the blade.

Tips That Help You

There are frequently trade secrets that may come in helpful when you’re in a bind. You’ll be able to locate and solve the out-of-balance issue quite quickly:

  • Tip 1: Always keep in mind that the right-hand nut rotates clockwise. The left-hand nut rotates counterclockwise.
  • Tip 2: Tighten the wheel balancing screws in a cross-hair pattern, starting from the outside of the wheel and working your way in.
  • Tip 3: If grinding on very hard materials causes spindle wobble or vibration, it may be necessary to use a heavier grinder wheel with larger arbor bearings. This will distribute the grinding force more evenly across the surface of the bearing and prevent deterioration or failure.
  • Tip 4: When replacing wheels on a regular basis, make sure to note where the washer is located. When you switch back to the original wheel, this will help you get back into balance.


Why is my bench grinder wobbling?

There are a few possible causes for bench grinder wobbling. If the motor is running too fast or the bearings are worn out, the bench grinder may start to wobble. If the grinder has been dropped or bumped, the motor may also be damaged and cause wobbling. In either case, it is necessary to take the grinder apart and inspect the parts for damage before fixing the issue. If necessary, new bearings or a new motor can be installed.

Why do some grinding wheels need balancing?

Grinding wheels need to be balanced for two main reasons: to ensure accuracy and to prevent damage. Without balance, the wheel may not rotate smoothly and may cause damage to the material being ground. Balancing the wheel also ensures that it is operating at its optimal performance.

How do you even out a grinding wheel?

Grinding wheels can become uneven due to the wear and tear that they experience while in use. To even out a grinding wheel, you will need to apply a lubricant to the wheel and then use it to grind the surface of the material being processed. Grinding with a lubricant will help to reduce wear and tear on the wheel and ensure that it operates more smoothly, resulting in a more even finish.


Properly balanced bench grinder wheels are essential for optimal performance and long-term durability. By following the tips and instructions outlined above, you can prevent debris from becoming clogged and keep your machine running smoothly.
