BLADE BASICS 101

A diamond blade is a circular steel disc with a diamond  bearing edge. The blade edge comes in three main types: segmented, with individual separate segments for long life; turbo, with continuous serrated edge for aggressive, fast cutting; and continuous rim, for smooth chip-free cutting. 

The core of the blade is made of tensioned steel and sometimes has slots. These slots (also called gullets) cool the blade by allowing water or air to flow between the segments. They also allow the core to flex and dissipate stress while cutting, so the blade is less likely to crack. All blades are designed to run at specific rpms. It’s essential for safe operation and optimum performance that blades run at the correct rpm. 

The diamond edge is made of a combination of manufactured diamonds and  metal powders. Different mixtures of diamonds and metal powders are used, depending on the aggregate being cut. During the manufacturing process, the metal powder and diamonds are bonded together at high temperatures to form  a solid metal alloy. This metal alloy is then bonded to the blade. A blade’s diamond edge is always slightly wider than the core so it doesn’t drag or bind in the material being cut. 

A diamond blade cuts by grinding through the material. As  the diamond edge wears, new and sharper diamonds are exposed.

CHOOSING THE RIGHT BLADE

Answer these simple questions when choosing your blade,  or ask your World Diamond Source representative for advice. 

1 What type of material is being cut?

2 Do you want a segmented, turbo or continuous  rim blade? 

3 What is the diameter of the blade?

4 Does the rpm of the saw, based on blade diameter, fall  within the guidelines? 

5 Will the blade be used in a wet cutting or dry cutting  application? 

6 Are you more concerned with the initial price or cost  effectiveness of blade?

WET BLADESLess
WET BLADES

Wet diamond blades must be used with a continuous flow of water to maximize performance and prevent excessive heat buildup. Water helps clear dust and cuttings away from the blade and slot being cut. Using a wet blade without adequate water, even for a few seconds, can cause blade damage and pose a safety hazard.

DRY BLADESLess
DRY BLADES

Dry diamond blades are designed to be cooled by airflow around the blade. They can be used either dry or wet. Note that every 10 to 15 seconds it’s necessary to take pressure off the blade and back it out of the cut, allowing it to run back up to full speed for several seconds. This technique cools the blade, maximizes performance and prevents excessive heat

buildup that causes damage.

HOW DIAMONDS ARE MADE

The exposed diamond crystals do the grinding work. The metal matrix or  bond holds the diamond in place. Trailing behind each exposed diamond is a bond tail which helps to support the diamond. As the blade rotates through the material, the exposed surface diamonds grind the material.

Eventually the diamond completely breaks apart and its fragments are swept  away with the material it is grinding. When the blade is cooled with water this material, included with water, produces slurry

After several thousand passes through the material, the exposed diamonds  begin to crack and fracture. The matrix holding the diamonds also begins to wear away

As the old diamonds are fractured and worn away they are replaced by new  diamonds and the process continues until the segments are worn down to the core.
