When selecting the correct saw blade to use in a project, it is essential to understand the various factors that play a significant role in the selection of an saw blade. Using the same saw blade for every project isnt advised as the type of wood and the type of cut required for the project will determines the correct saw blade to use. Using an incorrect saw blade can cause various problems to the saw and the project, such as create jagged edges in the project.
The first factor to consider when selecting the correct saw blade is the diameter of the saw blade. The diameter of the saw blade will determine the depth at which the saw blade will cut into the pieces of wood. Furthermore, the arbor hole of the saw blade must match the spindle of the saw.
How to Choose the Right Saw Blade
Should the arbor hole of the saw blade and the spindle of the saw not match each other, the saw blade will not be able to spin correct and may create a wobbly saw blade. For instance, 8-inch saw blades are usually used for smaller projects, while 12-inch saw blades is used for large industrial saw machines. Choosing a saw blade with the wrong diameter can prevent the saw blade from properly cutting the wood to the necessary depth.
The second factor to consider when choosing a saw blade is the tooth count of the saw blade. If a saw blade has fewer teeth, the gullet between each tooth will be larger. Larger gullets will allow the saw blade to quick remove the wood chips that are created during the cutting process.
Quickly removing the wood chips will prevent the saw from overheating during the project. On the other hand, saw blades with more teeth are used for saw blades that require the cutting of the saw blade across the grain of the wood. If the saw blade has fewer teeth than recommended for the project that requires the saw blade to be used across the grain, the saw blade will cause tearout in the project, which is the damage that the saw blade causes to the surface of the wood.
The third factor to consider when choosing a saw blade is the geometry of the teeth on the saw blade. For example, flat-top grind saw blades are efficient at cutting along the grain of the wood but are not ideal for cutting along the grain of the wood. Alternating bevel grind saw blades will act like scissor and will be ideal for saw blades that require the saw blade to be cutting along the grain of the project.
Some saw blades use a hybrid design for the teeth that allows the saw blade to efficiently both rip and crosscut the wood. No saw blade can perform every sawing task for a wood project correctly; hence, you will have to change saw blades according to the project. The fourth factor to consider when selecting the correct saw blade is the kerf width of the saw blade.
The kerf width is the thickness of the cut that the saw blade will make in the wood. The thinner the kerf of the saw blade, the less amount of wood the saw blade will remove. Thus, a thin kerf saw blade will require less power from the saw motor.
Full kerf saw blades will remove more of the wood, but they will remain straighter when sawing through thick wood projects. Furthermore, other factors to consider include the arbor size of the saw blade and the use of dado stacks. Dado stacks are sets of saw blades and chippers that are used to cut wide groove in the wood project.
Another aspect of a saw blade to consider is the condition of the saw blade. If the saw blade has dull teeth, it will not be able to cleanly cut the wood. Furthermore, dull saw blade teeth may cause the saw blade to scorch the edges of the cut wood.
Saw blades should of been sharpened every 20 to 30 hours of heavy use. Another aspect of the saw blade to consider is the hook angle. Steep hook angles will help saw blades to pull the wood aggressive into the saw blade.
Such saw blades are ideal for ripping projects. On the other hand, shallow hook angles will allow the saw blade to feed the wood more gentle. Such saw blades are ideal for crosscut projects.
By considering each of these factors, the saw blade that is used will be appropriate for the project, and the wood will be ready for the next assembly process.
