Laser welded and sintered are the two main manufacturing methods for professional diamond saw blades. Each offers distinct advantages depending on your job site requirements.
Professional contractors often ask whether laser welded or sintered diamond blades are better. The answer depends on material hardness, cutting speed requirements, and safety regulations on your job site.
Sintered diamond blades
Sintered blades are made by pressing diamond segments onto the steel core under high temperature and pressure. They are economical, widely available, and perform well on masonry, general concrete, and many stones. For light to medium-duty work, sintered blades offer excellent value.
Laser welded diamond blades
Laser welding fuses segments to the core with a high-energy laser beam, creating an extremely strong joint. These blades withstand higher peripheral speeds and heavy-duty cutting of reinforced concrete, asphalt, and hard stone. On high-power walk-behind saws and demo work, laser welded blades are preferred for safety and segment retention.
