Currently, most of the table saws like the best portable table saw have blades are made of two common materials: stainless steel and carbide. You have to find out what the material of your saw blade is. Because not all materials can be sharpened.

Stainless steel: This material is extremely cheap from only 20 USD. It is equipped in some types of cheap and not famous brand saws. In fact, with this type, I find that you can buy another one without sharpening it.

Carbide: different from stainless steel. This type is relatively more expensive from 40 USD to 60 USD. And you can see in most famous brands

Add: If you see any type of saw blade made of steel, but its teeth are made of carbide. This is the type that can be used for the longest time and its teeth are extremely sharp.

How to sharpen the saw blade?

Step One: Prepare the blade

First, use a brush or towel to scrub all the stains or debris off the wood that remains on the saw blade. You have to be careful not to miss the corner of the teeth. You can soak it into a special detergent to effectively clean it.

Step two: Remove the  blade from its position

After you have washed, you must leave the saw blade away from its position. This action is extremely easy and gentle. You also need to be sure to wear protective gear like a hand to prevent it from being scratched or injured when moving it out.

Step three: Sharpen the saw blade

This step is the central step of the whole process. Use a sharpener specifically for saw blades. You can buy it at any store that sells table saws or hand saw. As the second step, you still have to wear protective gear. Gloves that help you during grinding can blame if the blade is sharp again. And glass will help you avoid metal fragments when you accidentally hit the eye. If shooting in your eyes is extremely dangerous. Next, During the sawing process you should not rush, but be careful from a bit and follow the rule. First, you have to sharpen the front of the blade, one tooth at a time until you find it sharp enough to your liking, then switch to the back of the blade to sharpen it.

Step four: Lubricate and attach more to the saw blade

After sharpening, it can be used for a long time without sharpening again. You cannot skip this step, which is lubricating the oil for the blade. Use a brush then dip it into the oil you have prepared. Thoroughly spread all edges of the saw blade to achieve high efficiency. After the oil is applied to the blade, you need to let it dry for 5 to 10 minutes.

Add: As with hand saws, if you feel it cuts more slowly than usual, you can also lubricate it.

Step five: assemble the saw blade again

Now, you just need to reset the position you just took out. Remember to put it carefully and make sure it is not skewed, which is dangerous for the next saw.

Step six: Run test

Now check the sharpness of the saw blade. Try by a small piece of wood and put it through the saw that you just sharpened. If you see the wood going fast and smooth, your saw blade is already sharp enough. On the contrary, you find it still slow and not sharp enough, Let’s sharpen it again through the steps above.

In conclusion

I have finished expressing about how to sharpen saw blades for people who don’t want to spend a lot of money to buy new saw blades. Hopefully, this article will save you some money to buy one more needed. Thank you for taking the time to read this article.
