In the world of construction, the search for a more perfect cut has led to the search for a more perfect blade. Eventually, the engineers of construction saw blades turned their eyes upon diamonds: the hardest mineral on earth. As it turns out, for the right type of material, diamonds do indeed make the best saw blade available on the planet today.
What does such a blade look like? It’s a normal saw blade with diamonds attached at the end that grind through harder materials in a manner more effective than the way traditional blades slice.
It comes down to two things: precision and durability. Simply put there is no other substance on the planet that can offer as precise a cut or as durable a blade. When the job is to cut dense, hard, and abrasive substances that steel blades cannot touch – diamond saw blades are up to the task.
So, in industrial construction where extremely dense materials must be cut, or even in a jeweler’s workshop where gems need a precision cut, diamond saw blades offer optimal performance.
Different Blades for Different Materials
Depending on the specific type of material that needs to be cut, different types of diamond saw blades may be employed. There are three basic shapes of diamond saw blades created for three separate cutting jobs:
1. A circular blade: This is the most common type of diamond saw blade as it has the widest application of uses. This type is used often on construction sites and in commercial workshops. If you’ve had exposure to a diamond blade before but weren’t sure what type it was, this is like the type you worked with.
2. A gang saw: This specific type of diamond saw blade really only has one specific application, though it is widely used for that job: cutting stone blocks.
3. A band saw: This type of diamond saw resembles the traditional band saw and is used in the same manner on hard and dense substances. The only difference is this saw has diamonds affixed to its teeth.
Diamond saw blades are extremely versatile and can cut through anything, including concrete, asphalt, and other common construction materials.
Wet vs. Dry Cutting
With Diamond Saw Blades, because they grind the material down, an excessive amount of heat is produced during the cutting process. To prevent damage, injury, or errors while cutting, the blade must be actively cooled. Depending on the type of blade and material being cut, there are two different types of cooling: wet and dry.
In wet cooling, water is used to cool the blade, and in dry cooling, air is used instead. The proper type of cooling method is dictated by which is most effective with the material and type of blade in question.
Quick Tips & Facts
When using a diamond saw blade, all normal power tool precautions should be followed. Proper attire, including gloves, protective gear, safety goggles, and a helmet should be worn at all times to prevent flying debris from causing injury during cutting.
Additionally, as discussed, each blade is made for a specific type of material to cut and needs a different type of power saw. Blades should never be used on the wrong type of material or forced onto a power saw they were not designed for. This includes using diamond blades on traditional materials that do not require them as the way these blades grind is simply not designed to cut such substances. Both types of misuse increase risk of harm and breakage of equipment.
When starting a new major construction job, always consider investing in new blades to optimal efficiency and safety – just as you would with any other saw blades. While diamond saw blades do have a higher durability, they are put to the task cutting surfaces that require that extra durability out of them. Therefore, even though they are diamonds, they do wear down and must be replaced regularly just like any other blade.
