There are so many diamond blades on the market. How do you know which is the best 14 inch diamond blade for cutting concrete, brick, block, stone, or tile? Do you need a sintered blade or laser welded blade? Should the blade be continuous or segmented? How do you know you’re going to get the best diamond blade for the money to run in your cut off saw?
Types of Diamond Blades
There are three main types of diamond blades out there. Sintered, Silver Brazed, and Laser Welded. There’s also vacuum brazed and electroplated, but those aren’t what we’re talking about for a 14 inch cut off saw.
A sintered blade is basically a metal disc loaded into a mold. These are the most common style in the construction world. Around the edge of the mold, there is space for metal powder mixed with industrial diamond bits. The whole thing is heated until the metal powder melts and the disk is done. The center disk isn’t hardened and the blade can’t be as strong as one made with one of the other methods.
Silver Brazed Blades
Diamond Blades and diamond cutting disks make like this have the industrial diamonds embedded in silver brazing on the ends of the blades. The center disk can be hardened and the blades can be used in high-intensity environments. These blades must run with water or risk the silver braze melting.
Laser Welded Blades
Laser welded diamond blades focus the heat of the sintering process above on the cutting edges only. This allows for hardened center disks that withstand more intense cutting, and stronger cutting edges that can handle wet or dry cutting.
Segmented or Continuous Blades
Do you need a segmented or continuous blade for your job? It really depends on what you’re cutting. Segmented blades will carry dust or slurry (from water) away and make a faster cut. But they can also cause chipping. If you’re cutting tile or marble you’ll want a continuous blade to prevent chips and damage, leaving a smooth cut in your material.
Sometimes you get the best bang for your buck when you spend a little more all at once.
