High-Speed Steel Saw Blades: The Balanced Choice
Among multi-blade saw blades, high-speed steel (HSS) is the most affordable material. This alloy containing tungsten, molybdenum, and chromium is like "Iron Man's armor," maintaining both sharpness and toughness. It's especially suitable for cutting wood, soft metals, and other materials, and offers excellent value for money – ordinary woodworking saw blades usually cost less than 100 yuan, making them an ideal choice for DIY enthusiasts.
When dealing with challenging materials like MDF and aluminum alloys, saw blades with tungsten-cobalt carbide inserts come into play. This material has a hardness comparable to sapphire and is 5-8 times more wear-resistant than high-speed steel. However, it's important to note that it's like a "hammer made of glass"-while hard, it's susceptible to violent vibrations and is more suitable for the stable working conditions of professional equipment.
Cutting ultra-hard materials like tiles and quartz stone? Saw blades coated with diamond particles are the ideal answer. Through electroplating or sintering processes, millions of micron-sized diamonds are "embedded like stars" on the blade surface. Their cutting life can be more than 50 times that of ordinary saw blades, but the price is also correspondingly higher, making them more suitable for large-scale processing operations.
