The 13mm x 6TPI blade is the type of blade provided on some medium sized bandsaws when sold new. They are capable of giving a reasonable cut requiring a small amount of finish sanding while being able to cut slight curves in 10mm to 40mm material.
Blade selection:
The amount of Teeth Per Inch relates directly with the thickness of timber it is capable of cutting. The fewer the amount of teeth, the more sanding will be needed to clean up the surface yet will cut quite quickly, and the more the teeth the cleaner the cut will be, yet will cut a lot slower. Thicker timber is going to require a blade with less teeth to cope with such a cut.
The width of the blade, which is measured from the back of the blade to the tip of the teeth, will determine the radius the blade is capable of cutting, the smaller the blade means the tighter the radius possible. Likewise, the larger the size, the more it is designed for ripping in straight lines and less capable of cutting arcs and curves, to the point where only straight cutting will be done.
