With a good and proper bandsaw blade you get a cleaner better cut. In addition the task is done in a safer and healthier environment for both you and your property. Having the proper bandsaw blades also means that the cut will be a lot easier. Types of Blades There are three major types of blades. Each blade offers a cut that is perfect for various materials being cut. Using the proper type of bandsaw blade is an essential part of any bandsaw project. (a) Regular Tooth - These are the perfect bandsaw blades for those finer cuts you need to make in the material. The teeth are extremely fine and make for an extremely smooth cut. It is not suggested that you do a resawing project with a regular tooth blade. This can be dangerous to you and your property. Instead use one of the other blades mentioned below. (b) Hook Tooth - These are the perfect blades for difficult and hard materials. This is an extremely aggressive blade and should not be used by novices.
A bandsaw blade has to be matched to the job in hand and to a lesser extent to the size of the bandsaw. You would not try to rip a 2" board with a tenon saw nor crosscut plywood with a greenwood saw. You would select the right blade for the job and the same is true for a bandsaw. Just because the machine is powered does not mean that one blade will cut everything it wont. So we need a selection of blades dependent on what we are doing. Fortunately despite there being a vast array of blades to choose from we can do 99% of our normal work with just two or three different blades. Blade width Given that the challenge with a bandsaw is to get it to cut straight it is easy to think that the wider the blade the better and to a certain extent this is true. You are likely to get better results with a ½" or ¾" blade than a ¼" one. But the temptation is to go as wide as the wheels will take. Which is an inch or more.

The reason there is not a side load is the angle of the side of the tooth. The tooth is bent or set at such a sharp angle on the side that only the top corner of about.010 touches the wood fiber. Of course if you run your band excessively dull it does take on more side load. Now compare the gullet stretch per tooth. Remember both band bodies are .042. The set tooth has the total kerf stress divided between 3 teeth. The swaged full tooth carries the entire kerf stress per tooth plus the side load on 2 sides per tooth. It is easy to understand that the full tooth carries twice the load just because of the top width of .084. Then add the 2 sides of load and we have at least 3 times more tooth load per square inch than the set tooth bands have. What does this mean? From my experience the set tooth pound for pound will perform 2 to 3 times better than a full tooth of the same band width and thickness. This is true even if a special steel is welded to from the full tooth. Let me talk about the body of the band for a bit here. I have spoken of the distortion and how it changes the middle portion of the band to dish on the log side.
See that the fence as well the blade are at 90-degree to table. Choose a section of straight wood of up to three feet length. Draw a line in the center. Cut by hand down the line while maintaining the cut along the center line. Keep feeding at the usual speed. Once you get it straight clutch the wooden peace on the table. Switch off the machine. You already got the desired lead angle of this blade! Using a pencil draw a line straight on the table of bandsaw along the length of wood. With the help of a wrench loosen the bolts on the fence. Adjust angle on the fence alongside the pencil mark of the cut. Tighten the bolts. Now the fence is ready for the right lead angle of your blade. It delivers straight cuts. Fix it once once and keep going.
