A: When we say a diamond blade is “vacuum-brazed”, we mean that the blade has been coated in diamonds – kind of like how you’d dip an ice cream cone in sprinkles – and then vacuum-brazed to attach the diamond to the blade. Vacuum-brazing is superior to the metal bonding and electroplating methods used to make other diamond blades because it creates blades with all their diamond on the surface and ready to cut, instead of buried in a metal bond cutting segment.
Most manufacturers, if they use the vacuum-brazing process, will vacuum-braze individual segments, then weld these segments to a blade core. These welded vacuum-brazed blades may cut better than other blades. However, the welds holding the cutting segments to the blade core can heat up, soften and break. When segment welds break during cutting, the segments can fly off and endanger your life.
Blades like the Ductile Iron Safety Blade, Ductile Iron Ring Saw Safety Blade and Fire Rescue Safety Blade are unique because they have their diamond vacuum-brazed directly to the steel core, giving you in a stronger, solid steel blade without welds (up to 14″). This solid design eliminates the risk of cutting segment loss, increasing your safety.
