Maybe sintered msintered metaletal-bonded Diamond Saw Blades are the most common type。 A blade of this type is composed of a steel corepowder metal (the blade´s base is steel plate， unlike diamond wire) and diamond segments which are made by combining diamond crystals with powder metal and then sintering them。 The diamond segments are also known as the "cutting teeth" of the blade。

The steel core can vary in design。 Some of them have spaces (known as gullets) between each segment to provide cooling and slurry removal， while others have a single continuous rim for smoother chip-free cutting。 The type of core that has to be used depends of the type of materials that will be cut。 Generally，there are also three types of -bonded diamond blades: wholly sintered diamond blades， silver brazed Band Saw Machine and laser welded diamond blades。

A wholly sintered diamond blade is made by putting the steel core together with the diamondssintered metal and the metal bond materials into a mold and then sintering them in a sintering machine。 So the diameter of wholly sintered diamond blades is not very big and normally is not bigger than 400 mm。 Also because its participating in the sintering process， the steel core cannot be quenched， so the hardness and toughness of the core is not high。 Therefore wholly sintered diamond blades cannot be used in high-intensity tasks。

Silver brazed diamond blades and laser welded Diamond Saw Blade ， however， have no this problem。 Because their diamond segments and steel core are treated separately。 Their steel core can be quenched and processed with other heat treatments。 So these blades can be used in high-intensity tasks。 Silver brazed diamond blades´ diamond segments are brazed to the steel core via the silver solder which might be melted in dry cutting and this might cause security issues。 So silver brazed diamond blades can only be used in WET cutting。 While laser welding Diamond Cutting tools have a strong holding strength to the diamond segments even in high temperatures， so they can be used in dry cutting。
