How Diamond Band Saw Blades Are Made?

A diamond band saw is a saw blade that has diamonds etched on its edge for cutting abrasive or hard materials. Persons who are familiar with a regular table saw should have no issue using a diamond band saw blade. The exposed diamonds are captured in a metal matrix with each of them having a small cutting edge. The success of the diamond sawing will depend on factors such as: cutting speed, depth of the cut and the diamond blade selection along with the feed rate.

Different Diamond Blade Styles

There are different types of blades and some of the best table saw reviews on the market may also mention them:

  • Segmented Rim – gives the roughest cut. It has cut outs equal distances apart around the blade and allows for the cutting of surfaces such as brick, concrete pavers and limestone.
  • Turbo Rim – designed to cut better in either dry or wet applications. The turbo rim blade will cut faster due to the design of the rims pushing the material outwards.
  • Continuous Rim – also called a wet cut blade. This type of blade cuts at a slower speed than the others however it would provide the best finish. Water is used with this type of blade which helps to cool it down.

The Composition of Diamond Band Saw Blades

A diamond blade is made of high quality steel and is more powerful than a regular table saw however there are diamonds scattered throughout the blade. The diamonds which are embedded in the blade are produced through very high pressure and temperature synthesis, they are synthetic and are produced to encourage the most efficiency for cutting. The most important factor when it comes to how a diamond blade is made is the bond and there are different methods of bonding that can be used. The method of bonding which is used usually has an effect on the quality of the blade. There is a scale from soft to hard for bonds, the bond gives a base for the diamonds and allows for a wear rate to match whatever material is being cut.

Diamond Blade Variables

In manufacturing diamond blades there are variables of the saw that will help determine how well it cuts.

  • Bond Hardness refers to how well the bond matrix holds the diamonds. When there is an increase in the hardness of the bond, then there is also an increase in the diamond retention capabilities. The drawback of this variable however is that the cutting speed is lower. Different types of substances that are being cut will decide if a softer or harder bond is needed. The bond is measured on a scale from soft, medium or hard and the hardest bond matrix will usually result in a longer diamond blade life.
  • Diamond Grit Size/Mesh Size refers to diamond mesh/grain size that is used in a diamond blade. This variable is important in determining the surface finish quality, material microstructure damage you will obtain, the level of chipping you will obtain and the smoothness of the finish. A low size mesh will indicate a coarse grit while the higher size will mean a finer grit.
  • Blade Thickness can help determine the speed of your cut. The thinner the blade of the table saw, the faster it will run. Thin blades have advantages such as: less heat generation, better finish quality, faster cutting speed, minimum deformation of the material and less chipping of the material.

The idea of diamond blades success is the fact that diamonds are the hardest material on earth and so diamond blades can cut the hardest material. Many table saw reviews also mention the success of diamond blades.
