What is a Sintered Diamond Blade?

A sintered diamond blade is a diamond blade that uses the method of sintering to weld together the metal to the Diamond. Sintering is a type of welding that is used to attach the segments of a Diamond blade to the actual core of the Diamond blade. This method of welding uses heat to compact the metallic particles in a Diamond Blade to the actual diamond crystals. The diamonds are embedded within the metallic powder, which is separated by a lubricant at this point. When the powder is heated, the lubricant vaporises which leaves only the metal powder and the diamonds fused together.

Sintered diamond blade are used in cut construction, masonry, and various industries to cut the granite, marble, artificial stone, tile, brick and other materials.

How to distinguish sintered diamond saw blades from laser welded saw blades:

To differentiate between the two types, you can inspect the blade's edge. Sintered blades often have a continuous rim with evenly distributed diamond particles, ideal for smooth cutting. Laser-welded blades may feature segmented rims, providing faster cutting with gaps for heat dissipation.

Additionally, examine the blade's core. Sintered blades typically have a thicker core, while laser-welded blades usually have a thinner core to reduce vibration during operation.

Sintered is much cheaper than laser welded blades, which means you can get more blades for more money than laser welded blades.

How to distinguish sintered diamond saw blades from Electroplated blades:

Sintered blades often have a more solid and substantial appearance due to the densely bonded diamond and metal matrix. They are designed for heavy-duty cutting, such as in construction and masonry work. Electroplated blades, on the other hand, tend to look thinner with a layer of diamonds visibly attached to the cutting edge. These are typically used for intricate cutting in industries like jewelry making, electronics, and hobbies.
