How Are Diamond Blades Made? A Quick Guide

Diamond blades are an essential tool on a construction site. They are specially crafted and do not come cheap. So how can you check you are using the right one and getting value with your blade?

 

Below we discuss diamond blades. We take you through how they are made, and how to get the best from each type. 

 

Parts of the Diamond Blade

Standard diamond blades are made of two parts. These are the steel core and the segment. 

 

Steel Core

 

The steel core is a round metal disc. The diamond attaches to the outer section and it supports the outer segments. 

 

There are three ways in which the diamond attaches to the core. The first two, and most common, are vacuum brazed and sintered attachments. They are best used for cutting soft materials on equipment that is working on lower power levels.

 

The third is a laser welded attachment. This is a much stronger bond, best for cutting hard materials with full horsepower levels on your tool. They are typically more expensive than the other two types of core blades. 

 

Segment

 

The segment is made up of the diamond and the metal bonds. These are the parts that do most of the cutting in the blade.

 

The diamond is the part that does the actual hard cutting. When looking for a blade, the quality can be determined by the amount, quality, and size of the diamond in the blade. 

 

The bonding system holds all of these diamonds in place so that they can actually cut down on the material in question. It is made of a blend of metal powders which will determine its efficiency. 

 

As a general rule, remember that opposites attract when choosing blades. If you are cutting hard materials, you should generally buy diamond blades that contain soft bonds. If you are cutting soft materials, go for hard bonded blades. 

 

How Do Diamond Blades Work?

 

Diamond blades do not actually cut. They grind and actually act in a very similar way to teeth embedded in gums. This is on such a fine level; it often looks like a precision cut. 

 

Exposed diamond crystals are at the edge of the blade. Metal bonds hold them in place (imagine teeth in a gum). Behind each diamond is a bond tail, that acts as a root to hold the diamond in place.

 

When the blade begins to rotate, the exposed diamonds grind the opposing surface into a fine powder. This gives the appearance of a slice or cut. As the bonds and diamond wear down, they expose new sharp points of the diamond. 

 

After a while, the diamonds will eventually begin to crack, and the bonds will wear away. Once the whole unit blunts, the entire section of the blade will need replacing.
