Question 1

How many times can I sharpen circular saw blades?

Accepted Answer

Generally, a low-quality saw blade is not recommended to resharpen. They are poorly built, and sharpening them is a risk to the tool you are using. Reversely, a high-quality circular saw blade can be resharpened multiple times. You may reuse it unless the teeth get worn out.

Question 2

How can I maintain sharp blades for a long time?

Accepted Answer

Regular cleaning is the secret to sharp blades. Add it to your habits to clean the saw whenever you use it. You should wipe it with a damp cloth every time after use. Otherwise, the sawdust and debris will gradually reduce its performance.

Question 3

When should I replace my circular saw blade?

Accepted Answer

You should consider changing your circular saw blade when:

1. The blade consistently produces rough or inefficient cuts, even after sharpening.

2. When the teeth show significant damage, such as chipping or missing tips, it can affect the quality of the cuts. 3. A circular saw blade becomes worn out over time, reducing its diameter. If the teeth have started to appear too small, it is a clear sign that you should go for a new blade.

Question 4

Should I sharpen it myself or with the help of a professional?

Accepted Answer

Sharpening the saw blades by yourself is helpful, especially if you are a regular worker. It is beneficial to learn it instead of having professional service every few days. At the same time, a blade sharpener is also a reasonable investment to make.

In contrast, professional services are not as costly as you might think. Try to look for online sharpening services, as they usually charge less than a traditional shop.

Question 5

What is the best method to sharpen a circular saw blade?

Accepted Answer

When it comes to comparing the sharpening methods, each one is different from the others in terms of precision, time, and effort. If compared, sharpening by hand demands more time and effort, but it works well for acquiring precision. Alternatively, the angle grinder is a quick and more accurate option, but it requires careful adjustment. Meanwhile, sharpening the saw with a Dremel is a semi-hands-off technique. It provides high efficiency and requires proper monitoring. Sharpening with a blade sharpener saves both time and effort, but it costs a high price.

In short, choosing the right method depends on your preferences and the level of precision you desire.
