Nature of teeth
The teeth of a blade are the secret to its performance and are optimized for performing specific functions. A blade with more number of teeth will be capable of making finer and cleaner cuts than one with lesser teeth. The latter can be desirable for projects that require quick removal of material, without clogging either the wood or the blade. It is especially useful in projects where lengthwise cuts need to be made.
The angle at which the teeth are positioned also determines their performance. They can be positive, negative or neutral. An acute positive angle is good for removing material faster and making quicker cuts. However, it causes a lot of tears out. A negatively angled blade is the exact opposite.
Remember, the choice of the blade depends entirely on your project type. It is important to assess your project needs beforehand and equipped with this information, you should be able to pick just the right blade for yourself.
