Blade Size Chart

Choose the blade that best suits the thickness of the material being cut (or sawn). The ideal ratio is 2.5 to 3 teeth on the materials at any time. I have yet to add MM to this. Use a B and S gauge to determine the thickness if you need to. Now I would also caaution against listening too close to others when they say you MUST use a paticular size blade on certain gauges of metal. Depending on your job, and your personal taste, you may use a differant blade size than others.
As long as you have at least 2.5 to 3 teeth on the metal, you can use wht ever blade you would like.
Also. Remember to use some sort of blade lubricant!
