Introduction to the Universal Numbering System
The universal numbering system for plain-end scroll saw blades serves as a standardized method to identify and select blades across various manufacturers. This system simplifies the process of choosing the right blade for your specific project by categorizing blades based on critical characteristics such as width, thickness, tooth design, and teeth per inch (TPI).
How the Numbering System Works
Blades are assigned numbers that reflect their physical attributes and intended use. Smaller numbers, such as #2 or #3, indicate thinner, narrower blades with a higher TPI, making them ideal for intricate and delicate cuts requiring precision. Conversely, larger numbers like #7 or #9 denote thicker, wider blades with fewer teeth per inch, suitable for cutting through thicker materials or performing faster, rougher cuts.
Interpreting Blade Sizes
As the blade number increases, the blade’s width and thickness typically increase as well, enabling it to handle denser materials. The TPI decreases with larger blades, which allows for faster cutting speeds but less detailed work. This relationship helps users select the most appropriate blade based on the material’s thickness and the desired cut quality.
Why Pin-End Blades Are Different
Unlike plain-end blades, pin-end blades are designed with integrated pins at both ends, facilitating quick and secure mounting onto the scroll saw. Due to their mounting mechanism, pin-end blades generally come in standardized sizes that do not directly conform to the universal numbering system used for plain-end blades. Their larger size accommodates the pins, which influences their dimensions and selection criteria.
