Wood cutting: Cutting cork (such as pine and fir wood), with the option of a saw blade with a larger tooth pitch (8-14 teeth/inch), which can quickly remove chips and improve cutting efficiency; When cutting hardwood (such as oak and walnut), it is advisable to use a medium pitch (14-24 teeth/inch) saw blade to ensure a smooth cutting surface. For fine woodworking tasks such as making crafts and furniture components, ultra-fine dense tooth saw blades (24 teeth or more per inch) can achieve high-precision, burr free cutting.

Metal cutting: Cutting ordinary steel, such as low carbon steel and medium carbon steel, using high-speed steel saw blades, which contain alloy elements such as tungsten and molybdenum, and have good thermal hardening and wear resistance. When cutting difficult to cut metals such as stainless steel and aluminum alloys, a hard alloy saw blade is required. The alloy blade has high hardness and can withstand high temperature and high pressure. When cutting aluminum alloys, a saw blade with a large number of teeth and grooves should be selected to facilitate chip removal and prevent aluminum chips from adhering.

Plastic cutting: For cutting general plastic sheets such as PVC and acrylic, a fine toothed saw blade can be selected, with a tooth count usually between 60-120 teeth, which can reduce plastic deformation and edge breakage during cutting. For thicker plastics, reduce the number of teeth appropriately to ensure cutting force.

Thin material cutting: For cutting materials with a thickness less than 6mm, such as thin wooden boards and metal sheets, choose thin saw blades with a thickness of 0.8-1.2mm to reduce cutting resistance and material loss. At the same time, there are relatively more teeth to ensure cutting quality.

Thick material cutting: When cutting materials with a thickness greater than 25mm, such as thick solid wood and thick steel plates, a thick saw blade with a thickness of 2-3mm should be selected, matched with a larger tooth pitch to enhance cutting force, make the saw blade more durable, and prevent deformation during cutting.

Low power table saw: a small table saw with a power of 1-2 horsepower, suitable for saw blades with smaller diameters and fewer teeth, such as saw blades with a diameter of 10-12 inches and 30-40 teeth, to avoid motor overload.
High power table saw: Large table saws with a power of 3 horsepower or more can use saw blades with a diameter of 14-18 inches and a large number of teeth (50-80 teeth) to fully utilize the power of the table saw, improve cutting efficiency and quality.

Ensure that the saw blade aperture matches the diameter of the table saw spindle accurately. For example, if the table saw spindle diameter is 25.4mm, a saw blade with an aperture of 25.4mm should be selected. If it does not match, a suitable variable diameter sleeve should be used, otherwise the saw blade will shake during operation, affecting cutting accuracy and even causing danger.
Check the maximum saw blade diameter limit of the table saw. If the table saw indicates a maximum fit of 14 inch saw blades, a 16 inch saw blade cannot be installed to avoid exceeding the carrying capacity of the table saw and causing safety hazards.

Turn off the power of the table saw, unplug the plug, and ensure safety. Remove the protective device of the table saw blade and place it in a safe location.
Place the saw blade flat on the table saw worktable, and ensure that the direction of the saw teeth is consistent with the rotation direction of the table saw. Generally, there will be arrows indicating the rotation direction on the saw blade.
Align the center hole of the saw blade with the main spindle of the table saw, gently push it forward, and make the saw blade smoothly fit on the main spindle. Install a washer on one side of the saw blade, with a flat and smooth surface facing the blade, and then tighten the nut. Be careful not to tighten the nut too tightly, tighten it by hand first.
Install the saw blade protection device to ensure that it is securely installed and can function properly for protection. Finally, tighten the nut moderately with a wrench to secure the saw blade firmly, but avoid damaging the saw blade or table saw components with excessive force.

Before cutting, clean the worktable of the table saw, remove debris and debris, and prevent debris from getting caught in the saw blade during cutting, affecting cutting or damaging the saw blade. Fix the material to be cut on the workbench, using fixtures, pliers, etc., to ensure that the material does not move during the cutting process, ensuring cutting accuracy and safety.

Start the table saw and let the saw blade idle for a few seconds, observing whether the saw blade runs smoothly and whether there are any abnormal vibrations or noises. After the saw blade reaches normal speed, smoothly push the material for cutting, and the pushing speed should be uniform, not too fast or too slow. Being too fast can cause the saw blade to overload, increase wear, and even lead to blade breakage; If it is too slow, it will affect the cutting efficiency and may cause the saw blade to repeatedly rub against the material surface, damaging the cutting surface.

During the cutting process, the operator should stand on the side of the saw blade and avoid standing in front of it to prevent accidental cracking and injury. Keep a safe distance between your hands and the saw blade, generally not less than 15cm. If necessary, use a push rod to push small pieces of material.

Cleaning saw blade: After each use, wait for the saw blade to cool down, use a soft bristled brush or damp cloth dipped in neutral cleaning agent to gently scrub the surface and teeth of the saw blade, removing impurities such as resin, wood chips, metal shavings, etc. Do not use sharp tools to scrape the saw blade to avoid damaging the saw teeth. After cleaning, dry the saw blade with a dry cloth to prevent rusting.
Check the wear of the saw blade: Regularly inspect the saw blade serrations. If any serrations are found to be worn, dull, or broken, promptly address them. For minor wear, a specialized saw blade grinder or file can be used for grinding; If the wear is severe or there are many broken teeth, the saw blade should be replaced in a timely manner to avoid affecting the cutting quality and causing safety issues. At the same time, check whether the saw blade substrate is deformed or cracked. If so, stop using it immediately and replace it.
Lubrication and maintenance: Apply an appropriate amount of lubricating oil to the installation holes, bearings, and other parts of the saw blade at regular intervals to reduce friction, ensure smooth operation of the saw blade, and extend its service life. Be careful not to apply lubricating oil on the serrations to avoid affecting the cutting effect.
