Which Abrasive Disc should I use?

Products are divided into categories according to application, and subcategories according to the type of material to be worked on. However there are often multiple items available for use on the same material type. The following chart indicates the life, hardness and metal removal. The products with the most red circles filled in are the optimum product in each category, but not always necessary for every application. Our sales and customer service agents are always available for consultation to find the best wheel for the job!
