Compatibility Information
This grinding disc is compatible with variable-speed angle grinders, making it suitable for a wide range of applications, including cleaning, deburring, fine grinding, roughening, and surface structuring (matting, brushing, and satin finishing). For optimal performance, especially when working with materials that have poor heat conductivity, such as titanium and stainless steel, it is recommended to reduce the cutting speed significantly. An ideal cutting speed range is between 15–30 m/s, balancing stock removal rate, surface quality, thermal load on the workpiece, and tool wear.
