How to choose the right size grinding wheel and cutting wheel?

When selecting a grinding wheel or cutting wheel, users should consider two primary factors — diameter and thickness. Both metrics affect the wheel's usability and performance.

 

DIAMETER: The choice of diameter for a grinding wheel or cutting wheel generally depends on the available tool. The primary reason for fitting the grinding disc or cutting disc diameter to the tool is safety — the operation of the tool should never exceed the RPM rating on the abrasive. Smaller power tools tend to operate at higher RPM than larger power tools, and the design of abrasives and brushes enables them to meet the same standards. Running a wheel with only an 8,500 RPM rating on a grinder that operates at 13,000 RPM could cause the abrasive to fail and injure the operator. Choosing the correct diameter also enhances safety because it allows for the use of proper guards. Trying to fit a 155mm abrasive cutting disc on a 115mm grinder necessitates removing the protective guards, and running the grinder without guards would increase the operator's chance of injury if the abrasive failed. Product life is an additional factor in the choice of grinding wheel and cutting wheel diameter. Larger-diameter wheels last longer. Especially in applications where the operator must run the grinding wheel for a sustained period, using a larger-diameter wheel can improve productivity by reducing the number of times the operator must stop and replace the abrasive. The configuration of the workspace and workpiece also influence the choice of diameter. For instance, an operator working in a cramped space or on a tricky area of the workpiece may choose a die grinder with a small 3-inch wheel for better access.

 

THICKNESS: The thickness of a grinding wheel impacts its performance and wheel life. When selecting cutting-off wheels, making a decision often isn’t that easy. In addition to many obvious factors, such as the machine or area of application, various preferences also play a role. In practice, anyone who wants to professionally cut stainless steel, metal or other materials is faced with a choice: 0.8mm,1.0mm,1.6mm,2.0mm or 2.5mm etc. BINIC Abrasive Company can produce cutting discs of various thicknesses, whether it is inox cutting discs, iron cutting discs, metal cut off discs, stainless steel cutting discs, steel cutting discs or stone cutting discs, BINIC Abrasives Company can produce all kinds of products and size.

 

In practical applications, users can complete the work efficiently only by selecting products and tools with the appropriate diameter and thickness.
