The numbers and letters on jigsaw blades indicate the blade's type, tooth design, and application. For example, "T" or "U" refers to the shank type (T-shank or U-shank), while numbers like "T101B" specify the blade series, tooth spacing (TPI - teeth per inch), and the material or cut type the blade is designed for. This coding helps users select the right blade for specific materials and cutting tasks.
