Material Determines Saw Blade Lifespan
The saw blade material is like a warrior's armor, directly determining its durability. Currently, the mainstream choices are high-speed steel, tungsten carbide, and diamond coating:
High-speed steel: High cost-effectiveness, suitable for cutting soft wood or plastic, but prone to overheating and dulling during continuous work.
Tungsten carbide: Hardness increased by 3 times, suitable for metal, hardwood, and other materials, maintaining sharpness for a longer time.
Diamond coating: A powerful tool for cutting tiles and stone, although the unit price is high, its service life can reach 10 times that of ordinary saw blades.
Tooth Shape Affects Cutting Effect
Saw teeth are like a chef's knife skills; different designs correspond to different scenarios:
Flat teeth: Produce a smooth cut without burrs, suitable for precision cutting of acrylic and thin wood panels.
Trapezoidal teeth: Alternating angle design, increasing cutting speed by 20%, suitable for quickly processing wood and aluminum.
Wavy teeth: Reduce material adhesion, an ideal choice for cutting PVC pipes and composite panels.
Matching Saw Blades to Materials
Just as different ingredients require different knives, common materials are paired as follows:
Wood processing: Choose an 8-10mm thick tungsten carbide saw blade, with a tooth pitch of 4-6mm being optimal.
Metal cutting: Thin diamond saw blades with coolant to prevent material overheating and deformation.
Composite materials: Fine-toothed saw blades with special coatings to prevent delamination or chipping.
