The Diamond Multi-Purpose Saw Blades are engineered to deliver precision, durability, and versatility for both professional contractors and DIY enthusiasts. Each blade is manufactured with premium-grade diamond particles, ensuring smooth, sharp, and chip-free cuts across a wide range of materials including marble, tile, stone, concrete, steel, PVC pipes, and even wood.   Designed with an ultra-thin 1.4mm high-manganese steel matrix, the blades minimize cutting resistance, reduce vibration, and provide enhanced control during use. This makes them ideal for precise cuts while offering a comfortable grip and effortless handling.   The blades feature an advanced brazed one-piece construction, which significantly increases toughness, prevents tooth shedding, and guarantees long-lasting performance even in demanding cutting tasks. Whether used for small household projects or heavy-duty construction work, these blades deliver consistent reliability.   To further improve performance, the saw blades are designed with Great Wall-style teeth and multiple cooling holes that allow efficient chip removal and improved airflow. This reduces heat buildup and prevents deformation, ensuring continuous high-speed cutting without compromising accuracy.   Compatible with most standard cutting tools, these 4.5-inch blades feature a 0.87-inch arbor hole for easy installation on angle grinders and marble machines. Their versatile design makes them suitable for tile installers, stonemasons, metalworkers, plumbers, and DIY hobbyists.   Product Specifications:   Blade Diameter: 4.5 in (11.5 cm)   Arbor Hole: 0.87 in (2.2 cm)   Cutting Thickness: 0.05 in (1.4 mm)   Material: Diamond-coated high-manganese steel   Applications: Marble, Tile, Stone, Concrete, Steel, PVC, Wood   Weight (per blade): 120g   Packing List:   1pc * Diamond Multi-Purpose Saw Blades
