Factors that cause saw blades to rust are usually: damaged packaging and relatively humid places. Water mist is easily generated here and comes into contact with the carbide saw blade from the damaged entrance, causing oxidation.
It's also possible that liquid seeped into the blade packaging where the blade was stored, causing oxidation and leading to rust. Therefore, when we are not using the saw blade, we must pay attention to its placement and keep it ventilated and dry.
What to do if the saw blade is rusty
If the saw blade is found to be rusty, do not use it as usual at this time. This can easily cause damage to the saw blade, especially blade chipping. Rust removal and other operations must be carried out before use.
Check for rusty areas first. If it's the basic part, it's easy to deal with. Just use our usual rust removal methods.
If the rusty part is at the jagged position, that's a bit troublesome. This situation must be handled with a diamond grinding wheel because the teeth are the most sensitive part of the saw blade. Once handled improperly, it will seriously affect the carbide. The use of the saw blade is likely to cause the saw blade to be scrapped.
