Introduction
A diamond saw blade is one that comes with diamonds that are fixed on the edges. They are designed for cutting abrasive or hard materials. In general, they are designed for different types of cutting tasks. As a professional mason, I find diamond blades useful for cutting materials such as granite, marble, asphalt, concrete and much more.
It was only until recently that I found the benefits offered by this type of saw blade.

Who Should Buy These
While conventional saw blades are designed for both professional and beginner users of circular saws, diamond blades are created for those who have advanced knowledge in the trade. These are the types of people who constantly have to deal with cutting tougher and stronger materials, including tile, marble, and others.
These diamond blades, technically, do not do the cutting. The cutting action happens when the blades start grinding the materials through friction using its diamond bonding matrix. This is one principle that is considered as basic and should be familiarized by those who opt to choose this type of saw blade.
Buyer's Guide
Which Diamond Blades Should You Purchase?
Perhaps you have already noticed that there are different types of diamond blades that are available for selection. Which one are you supposed to get?
Segmented Rim
Diamond blades with segmented rims are those that offers the roughest cuts. As such, they are ideal for use on cutting bricks, concrete, masonry/block, concrete pavers, limestone, as well as hard/reinforced concrete.
This type of blade is typically referred to as dry cutting blade. This is because of the cut outs, or the segments, designed on the blade edges. These allow air flow and a cooling effect on the blade core.
Continuous Rim
Blades with a continuous rim are usually referred to as the wet cut blades. This means that water is used when cutting materials. This offers some benefits because water cools the blade down significantly, thus ensuring longer life.
Continuous rim diamond blades cut the slowest among different types of blades. As a tradeoff, however, it creates the best cut you can expect. As such, they are ideal for cutting granite, marble, ceramic tile and porcelain tile.
Turbo Rim
Diamond blades that are equipped with a turbo rim are designed especially to cut faster in both dry and wet applications. The rim comes with smaller segments which allow for blade cooling, alongside the use of a diamond matrix for integrated interweaving.
The turbo rim allows air to pass through the smaller turbo segments, creating a cooling effect applied on the blade. Because of the design, the blade can cut faster, effectively cutting through bricks, concrete, as well as limestone materials.
Tips for Buying a Diamond Blade
The ever progressing advancements in technology have resulted in the creation of different types of diamond blades. This is good for most parts, but it can also tend to bog down your capability to make an accurate decision when purchasing.
To be guided accordingly, there are certain tips that you can take into consideration. Here are some of them:
Understand the Basics
It is very important to know how a diamond blade actually works. This will allow you to select a blade that is equipped with the right features and characteristics to perform cutting tasks. The diamonds that are exposed on the segment surface are the ones that do the cutting, performing an abrasive action in order to slice through different materials while the blade rotates at high speed.
It is also very important to know that the hardness level of the matrix is the one that controls how fast a blade can wear off. Therefore, when purchasing, a diamond blade which is used in cutting abrasive and soft materials should come with a hard metal bond in order to ensure that the exposed diamonds are utilized fully before shredding away.
Materials to Cut
To expect optimum blade life and cutting speed, it is very important to match the blade type to the type of material that you are cutting. The features of the material that you have to know includes the aggregate hardness and size, compressive strength as well as the type of sand that is used.
If you need to work on various types of concrete materials, it is recommended by manufacturers to select a blade depending on the type of material that you will be working closely the most. Most models of diamond blades are designed to cut a wide range of materials.
Wet vs. Dry Cutting
The decision whether you cut wet or dry highly depends on the requirements of the job, and your personal preference. Wet cutting can reduce the dust, but you may need to deal with the slurry later on. On the other hand, dry cutting will save you from the messy and watery slurry, or the need to equip your saw with tanks of water and hoses. If you are cutting in an indoor environment, a dry cutting blade may prove to be the best choice.
