Cutting Wheel

Cutting Wheels, also known as Cut-Off Wheels are abrasive wheels that are used for cutting all sorts of metals, steel, iron, ceramic, concrete etc. This blog will discuss and demonstrate the various types of cutting wheels, the industries that use them and how they are used.


Cutting Wheel, Cut Off Wheel

Cutting Wheels, also known as Cut Off Wheels, are wheels or discs that are typically used with a grinder tool, chop saws and circular saws. They are called cut off wheel mainly due to the fact that they are commonly used to cut reinforcement bars, trimming of excess material and for cutting off protruding parts such as nails and bolts. This is true in the construction, fabrication facilities, manufacturing, automotive, aviation and other similar industries. Generally speaking, there are five (5) characteristics that define abrasive cutting wheels, they are;

1. Material - The material of the actual abrasive.

* The choice between the different abrasive material is based on the hardness of the material being cut.

- Aluminum Oxide (A)

Aluminum Oxide Cut Off Wheel

Aluminum oxide cutting wheel is the most common abrasive used in cutting wheels. It is the most commonly chosen abrasive material for cutting and grinding carbon steel, alloy steel, annealed malleable iron, wrought iron, bronze and ferrous metals. Aluminum Oxide grains are coarse, tough and exhibit long life.


- Aluminum Zirconium (Z) and (ZA)

 Aluminum Zirconia Fiber Disc  Aluminum Zirconia Fiber Disc is the toughest abrasive comprised of aluminum. It is a very fine and dense grain of abrasive. These Abrasive Wheel are typically used for very rapid and aggresive stock removal. Aluminum Zirconium Abrasive Wheel are extremely durable.


- Silicon Carbide (C)

Silicon Carbide Cut Off Wheel feature a sharper grain shape which makes it an ideal abrasive for cutting concrete and other masonry applications. Silicon Carbide is a hard abrasive and is more brittle than Aluminum Oxide. Silicon Carbide is also used for non-ferrous metal grinding, such as aluminum metal, but is considered not to be the ideal abrasive for such applications.


- Ceramic (C)

- Diamond (D, MD, SD)

- Cubic Boron Nitride (B)

2. Grain Size, widely known as Grit


3. Wheel Grade


4. Wheel Bond


5. Grain Spacing
