Let’s glance over a few important facts before you start sharpening your table saw blades.

Perks of Sharpening a Table Saw Blade

Maintenance does wonders to your power tools, mostly table saw blades. Not only do they help to boost the cutting capacity, but they also ensure the safety of delicate woods.

Despite these, when you sharpen the blades on a regular basis, it increases the quality of the cut as well as refines the motor’s caliber. Not necessarily only when your blades get blunt, you should fix it by regaining the sharpness. You can also sharpen the machinery after intense working sessions.

How to Spot a Dull Table Saw Blade?

The first and very common sign, which is an identifying trait of the blunt blade, is resistance when you are cutting through an object. We mean when you are putting extra effort than usual to make a single cut, it’s the very moment when you realize that the blades need a life.

Besides, your blade might cut through without much pressure, but what if it makes shrill noise?

Yes, you guessed it right!

That’s also a sign of dull blades. What else can be the symptoms? Well, other circumstances like uneven edges, apparent chips, and splinters, etc., are also the consequences of the blunt and dull table saw blades.

If you notice any of these scenarios, it’s time to take action and sharpen the blades to revive the sharpness.

Sharpening a Table Saw Blade – Explained!

Here, we will tell you how you can recover the sharpness step by step.

Step 1: Safety Measures

Before you start, you must take safety measures; as we all know, safety comes first. Unquestionably, the blade is still sharp enough to cut your delicate skin.

And as you are supposed to stay in close contact when doing the task, you will require protection to prevent injuries. Here, you will need safety gloves and a nice pair of goggles.

Make sure that the gloves are strong and thick enough to resist the blade teeth to enter.

And the goggles should save your eyes from flares or sparkles. One more thing that you need is earphones.

As we all know, the piercing noise is very intense and often results in fatigue or harming the eardrums. Hence, make sure you grab these essentials before you start.

Step 2: Make a Friendly Environment

The second thing you gotta do is to keep the work surface as spacious as possible so that you can rest your hand comfortably. Often our working space becomes narrow and confined due to excess storage of materials.

Even you might put things on the table saw machine absentmindedly. Hence, before you move into the next step, make sure the work surface is user friendly and safe.

Step 3: Replace the Blade with a Diamond Blade

Now, you need to set up the blade for sharpening. And to do so first thing first, you have to buy a diamond blade. These blades are used to regain the sharpness of your table saw blade.

You can find them on Amazon or any local machinery store. Make sure you do a little research before buying them as there are some expensive-looking blades with zero capacity.

We suggest the Kobalt 10-in Wet Continuous Diamond Saw Blade 30825, which is not only affordable but also adequate.

Once you have the diamond blade in hand, you need to remove the table saw blade and insert the diamond blade. To remove it, you need to turn off the power supply. Raise the blade, loosening and pulling out the arbor nut, and the next thing you do is to remove the blade from its shell.

After placing the diamond blade in place, move forward for the main step.

Step 4: Sharpening the Table Saw Blade

Here, you have to sharpen the blade. First, turn on the power supply of your table saw blade so that it starts spinning. Now, start moving the saw blade fleetingly against the diamond blade—one tooth at a time.

However, if your table saw blade has teeth that are positioned towards one direction, you can keep going by turning the whole coil.

Now, if the teeth are pointed in both directions, you have to perform one swipe for each direction.

When you start, make sure to drag a fine line or mark on the teeth you touch at first against the diamond blade so that you know once you are done sharpening all of them. Just continue doing it until you reach the “starting mark.”

Note: Don’t forget to secure the diamond blade. In this regard, you can tighten the arbor nut so that it stays in place firmly. However, avoid tightening too stiff or too loose. Because an excessively tight nut might damage the diamond blade, whereas a loose nut is not capable of holding it in place.

Step 5: Disengage the Diamond Blade

Once you are done, it’s time to remove the diamond blade and replace the sharpened one where it belongs. Ensure cleaning the table saw blade before you put it in place as debris might build-up due to churning.

Step 6: Test the Sharpness

After you have reinstalled the table saw blade take a sample wood board and initiate the cutting process. If it cuts well without any resistance, extra pressure, or loud noise, it means you have successfully sharpened your tool.

On the flip side, if you still find any trace of dullness or want to increase the durability of your blade, consider using lubrication oil. Don’t use it too much as the blade is already sharpened. Few drops will do the work just fine.

Bottom Line

That’s a wrap! We hope your table saw blade would chop off the woods like a monster as you sharpen it. Make sure you follow each step, especially the safety measures.

Now all talk aside, adversity might stride in, and your blades may not work like before even after following these processes.

 In this case, you may need to buy a new one instead of repairing or sharpening. Assess your tool carefully to find serious errors so that you don’t have to waste your time and energy in the wrong place.
