Grinding wheels, flap discs and cut-off wheels Your quick product selection guide + Application + Material A prerequisite for the efficient use of abrasive wheels is choosing the right wheel for the specific application, the workpiece material and the available power tools. ➔ Power tools Starting with your application, the table below will guide you to one of the four main categories of this catalogue section. The sub-category navigation takes you to the right product, and finally a specific EDP number. PFERD adheres to a consistent colour coding for workpiece materials. The material table below shows an overview. Application Best abrasive wheel Generally, PFERD abrasive products work on every angle grinder. However, some are optimized for high- or low-powered power tools. When special power requirements are recommended, you will see notes in the product descriptions. The power tool table below shows our classification.
