MICRO-HOOK: Extremely precise engineering results in a hook face that is virtually flat. Never worry about irregular scratches caused by hooks from the interface pad. A flatter face ensures increased and more uniform contact by the abrasives. STRONG GRIP, EASY TO REMOVE: Micro-Hook pads are extremely secure in the lateral direction, while allowing easier removal for quick disc changes. Designed for Kovax Total DRY Hi-Tech abrasives such as Super Assilex, Yellow-Film and much more. Use on any sanding application that requires the best finish. MADE IN JAPAN: Manufactured by Kovax, leaders in coated abrasive technology for over 90 years in the automotive, metalworking, and woodworking industries. When used between Super-Tack back-up pads and abrasive discs, these durable interface pads will increase flexibility and provide extra cushioning, thus minimizing deep scratches and improving finish quality.
