The number of teeth per inch refers to the number of cutting surfaces on the blade. Blades with higher TPI are ideal for making intricate cuts, while blades with lower TPI are better for cutting thicker materials.
For inside cuts, a blade with a higher TPI is recommended as it provides finer and more precise cuts.
Remember to always follow the manufacturer’s recommendations for the specific scroll saw you are using and consult the user manual for proper blade selection.
Understanding blade teeth per inch
In order to make inside cuts with a scroll saw, it is important to understand the concept of blade teeth per inch (TPI). The TPI refers to the number of cutting teeth per inch on a scroll saw blade. This measurement determines the blade’s ability to cut through various materials.
Choose the right TPI
When making inside cuts, it is crucial to select a blade with the appropriate TPI for the material you are working with. Generally, the higher the TPI, the smoother the cut will be. However, the higher TPI blades are more suitable for thinner materials. For thicker or tougher materials, a lower TPI blade might be more effective.
For intricate inside cuts, blades with a higher TPI, such as 20 or 22, are recommended. These blades are ideal for cutting through delicate materials like plywood or veneer, as they provide a smooth and clean cut.
On the other hand, if you are working with harder materials, like hardwood or metal, a blade with a lower TPI, such as 10 or 12, would be more suitable. These blades have larger gaps between the teeth, allowing for efficient cutting through tougher materials.
Consider the thickness of the material
Another factor to consider when selecting the appropriate TPI is the thickness of the material you are cutting. Thicker materials may require a lower TPI blade in order to cut through effectively. Using a blade with too high of a TPI for a thick material may result in the blade getting stuck or breaking.
Conversely, when working with thin materials, using a higher TPI blade will provide more control and precision in making inside cuts. The fine teeth of the blade will navigate intricate patterns with ease, ensuring clean and accurate cuts.
It is important to experiment with different TPI blade options to determine which one works best for your specific project. Each material can have unique characteristics, and finding the right blade TPI will greatly impact the quality of your cuts.
