What are thin kerf blades and when would I want or need one?
The teeth on thin kerf blades are more narrow than standard saw blades. Which means that they cut less wood. And that means the saw motor doesn’t have to work as hard.
So if you have an underpowered saw, cutting hard and thick woods these thin kerf blades are a good option.
The drawback to using a thin kerf blade is that since the teeth and blade itself is thinner, the blade can flutter as it’s cutting which will cause a rougher cut that may need to be cleaned up.
