Sand-Light blending discs have an arbor hole for easy mounting to the grinder shaft. Less aggressive cutting than traditional surface conditioning discs, these are excellent for minor finishing and blending applications and final finishing prior to buffing with compounds. Use the slowest speed possible for optimum results. Two Sand-Light grades available: Medium (general purpose) for light finishing after using surface conditioning discs and blending surface imperfections; and Very Fine for blending surface imperfections, final finishing and preparations prior to coating. Use Very Fine followed by SAIT Buffing Discs and compounds for a near mirror finish. For use with aluminum, stainless steel, ferrous and non-ferrous metals. Package of 10.
