A diamond blade is a cutting tool that features a steel core with diamond segments attached to its edge. These segments are made from industrial-grade diamonds, which provide exceptional hardness and durability. Diamond blades are commonly used for cutting hard materials such as concrete, asphalt, brick, and stone, making them essential in construction and masonry work. The effectiveness of a diamond blade comes from its ability to maintain sharpness over time, allowing for cleaner cuts and reduced wear. They are available in various sizes and types, including wet and dry blades, to suit different cutting applications and equipment, such as saws and grinders.
