The right diamond blade can mean the difference between an efficient, cost-effective and profitable job or one with additional costs and downtime. Knowing how to select the right blade for the right machine that is designed to cut the right material can save construction business owners time and money and increase profits. Owners should ask themselves five basic questions when choosing the right blade for a project and use this knowledge to correctly bid on projects as well as minimize the chances of troubleshooting blade issues.
1. Which materials are you cutting?
Correctly identifying the material to be cut directly affects the cutting speed and the life of the blade. Most blades are designed to cut a range of materials, which is limited by the hardness of the bond and the diamond quality used. However, for maximum performance, the blade should be matched as closely as possible to the material it will cut.
When cutting concrete, asphalt or green concrete, it is important to know what makes up the material. Knowing the type of aggregate within the slab is your best bet at finding a blade optimally suited to cut it. You can determine what is in the slab by observing and looking to see what aggregate is used, or by using a Mohs test. A Mohs test helps identify the hardness of the aggregate, which can help determine what type of aggregate you are up against. Most diamond blade manufacturers will specify which of their blades either cuts a particular type of aggregate (flint, river rock, limestone or abrasive sand, for example) or will list aggregate categories (hard, medium or soft). These aggregate and material charts will help narrow your blade selection to only the blades that will cut that particular type of aggregate.
2. What type of equipment are you using?
Knowing if you will be using a 5-hp power cutter or a 70-hp flat saw will impact blade choice dramatically. The size of the blade acceptable to use on the saw, the ability to use a wet or dry blade and the rpms needed to spin the blade all depend on the equipment.
Blade size&#;Blades are engineered to be used on specific equipment. It is critical to select a blade that can be run on the equipment you plan on using.
Wet or dry blades&#;Most equipment will have the ability to use water, but there may be a time when water can&#;t be used or isn&#;t available.
RPMs&#;If a blade is run too fast or too slow, the blade will not work effectively and a loss of tension or excessive wear on the blade could result. Blades should list a maximum safe speed in revolutions per minute at which a blade can be used. Before using any blade, make sure the blade shaft (arbor) speed or the tool is within the &#;maximum safe&#; limit of that blade.
3. How deep are you cutting?
Knowing how deep you need to cut on a particular job will help you select the right blade diameter. Maximum cutting depths listed on blade packaging may vary from what it actually cuts in the field. Actual cutting depth will vary with the exact blade diameter or saw type or the exact diameter of the blade collars (flanges). Cutting depth will also be reduced if saw components (motor housing and blade guard) extend below the blade collars.
4. Are you cutting dry or wet?
Knowing whether or not you will have or need a water source on a job is important when selecting a diamond blade. Blades designed to cut dry can also cut equally well wet, but wet cutting blades absolutely must be used with water.
Dry-cutting diamond blades should be used only for shallow cutting (1- to 2-inch deep) or step cutting (making several shallow passes to reach the full depth required). Dry blades depend on airflow around them to prevent excessive heat buildup during cutting.
They are a good choice for &#;intermittent&#; sawing. Wet-cutting diamond blades must be used with water to prevent excessive heat build-up during cutting. Using water on the blade also reduces hazardous dust. Continuous water flow on wet-cutting blades is critical. Using a wet blade without water, even for a few seconds, causes excessive heat and blade damage and creates a safety hazard. Check the saw or tool carefully before using a wet-cutting diamond blade to make sure it is safe to use with water.
5. Do you want more life or speed?
Which is more important: the initial price of the blade or the cost per cut? It may be more cost effective to purchase a low-priced blade for a smaller job or occasional use. For larger jobs or more regular use, a higher priced blade will actually be less expensive to use because it will deliver the lowest cost per cut. For extremely large jobs, the lowest possible sawing cost (cost per foot) is usually much more important than the initial price. Manufacturers will list performance/quality levels on blades so it is easy to select the blade with either more life or more speed.
Answering these simple questions to select the right blade will save a lot of time, money and headaches in the field.

When it comes to tackling tough cutting jobs in the construction industry, having the right tools is essential. Diamond blades are a popular choice for professionals who work with materials like tile, stone, and porcelain. With their superior cutting power and durability, diamond blades are a valuable asset in any contractor's toolbox. In this comprehensive buying guide, we will walk you through everything you need to know to select the ideal diamond blade for your specific needs. So, let's get started!
Selecting the right diamond blade is paramount to achieving clean and precise cuts in different materials. Before making a purchase, consider the following factors:
When purchasing a diamond saw blade, it's crucial to consider a few essential factors:
To make an informed purchasing decision, it's important to understand the key characteristics of diamond saw blades:

For tile cutting, our collection includes diamond blades with a continuous rim or a segmented rim. Continuous rim blades are perfect for achieving smooth cuts in ceramic, porcelain, and glass tiles. On the other hand, segmented rim blades are ideal for cutting through harder materials such as natural stone tiles or thicker porcelain tiles. These blades provide faster cutting speeds and improved debris removal.

RTC T3 Razor 10" Diamond Blade
When working with natural stone, we recommend using diamond blades with a turbo rim design. Turbo rim blades have specially designed cutouts that help to dissipate heat, ensuring cooler cutting and preventing the blade from overheating. They provide excellent cutting performance on materials like granite, marble, and travertine.

While diamond blades excel in cutting hard materials, it's essential to understand how they compare to other blade types:
Can I use a tile blade to cut stone?
It is not recommended to use a tile blade for cutting stone. Tile blades are designed for cutting softer materials and may not withstand the hardness and abrasive nature of stone. It's best to choose a diamond blade specifically designed for stone cutting to ensure optimal performance and durability.
How long do diamond blades last?
The lifespan of a diamond blade depends on various factors, including the quality of the blade, the material being cut, and the cutting technique employed. Generally, diamond blades can last for several cutting hours, but it's essential to monitor the blade's condition and replace it once it becomes dull or worn out. Regular cleaning and maintenance can also help prolong the life of the blade.
What safety precautions should I take when using diamond blades?
When working with diamond blades, always prioritize safety. Wear appropriate personal protective equipment, including safety glasses, gloves, and hearing protection. Follow the manufacturer's instructions for blade installation and ensure the blade is securely mounted. Avoid cutting materials that are unsupported or unstable, as they may cause the blade to bind or kickback.
