What is the significance of a tool's RPM rating?

The RPM (revolutions per minute) rating of a tool is significant because it indicates the speed at which the tool operates. This measurement tells you how quickly the tool's motor can turn its blade or bit, which in turn affects its performance and the quality of work it can accomplish. For example, higher RPM ratings typically mean faster cutting, drilling, or grinding, which can improve productivity for tasks such as woodworking or metalworking. The appropriate RPM for a particular job can vary based on the material being worked on and the type of tool being used, making this rating crucial for selecting the right tool for a specific task. Understanding the RPM helps ensure that the tool is used effectively and safely.
