​There are two ways to sharpen the blade of a table saw. Method 1 entails using a file to manually sharpen the edges of the blade.

The second method is less stressful compared to the first but getting the grinding wheel – which can be used several times – adds to the cost.

How to Sharpen a Table Saw Blade - Step by Step Instructions

In ensuring you have a perfect understanding of how to sharpen the blade of your table saw, we have compiled our set of tested and trusted step-by-step instructions to make things easier. Follow these steps, and you will get this done sooner than you thought possible.


Method 1

  • Step 1 - Turn off the power

It’s important you turn off the table saw and remove its connection to the power outlet. Accidents happen but many are avoidable.

  • Step 2 - Remove All Debris

Use the hand brush, soap and water to remove all debris from the teeth of the blade. This is a buildup towards restoring the blade to its sharper form.

  • Step 3 - Apply the Grease/Oil

Apply oil or grease to the blade. This makes it more vulnerable towards the sharpening exercise. Also, it helps in the removal of dirt stuck around the blade of the table saw.

  • Step 4 - Use your safety gear

Before you proceed to commence the sharpening exercise properly, you need to protect yourself. Protective goggles, hand gloves, face mask, and earmuffs would help to achieve that to a reasonable extent, but you’d still need to be careful.  

  • Step 5  - Sharpen the Blade Using the sharpening stick

Place the sharpening stick on a wooden support and bring it in close proximity to the suspended blade. To sharpen the blade, you would need to continuously rub the sharpening stick against the teeth of the blade in an oscillatory manner. Endeavor to oil the metallic part of the sharpening stick to improve the efficiency of the process. This is repeated until the blade is visibly sharp.

Method 2

  • Step 1 - Disconnected the Blade from the Table Saw

The blade plates of a table saw are usually held in position by screws. Unscrew this hold on the plates, and remove the blade by turning the nut in an anticlockwise direction using the wrench.

  • ​Step 2 - Mount the Diamond Wheel on the Table Saw

Attach the diamond wheel to the table saw. You can use the accessories of the detached blade to do this. Subsequently, support the blade on a wood which ensures the accessibility of its teeth.

  • Step 3 - Turn on the table saw
    With the diamond wheel fully in the stead of the blade, turn on table saw. The wheel shouldn’t be out of place despite its different construct than the blade.
  • Step 4 - Sharpen the Blade


As the blade is supported on a wooden base, bring it towards the revolving diamond grinding wheel. It is important you do this for each individual tooth on the blade. Aim the revolving wheel at the space between the teeth and move the blade to next after several seconds.

  • Step 5 - Re-attach the Blade to the Table Saw


Detach the diamond grinding wheel and return the blade to its original position. You will need to secure the blade plates and relock the blade.

Conclusion

Hopefully, this guide has provided enough insight on how to go about sharpening the blade of your table saw. Safety cannot be overemphasized when sharpening the blade, so be very careful. Your ingenuity would be called to action when constructing the support for the blade – if you opt for the second method – so be ready for that.
