Premium Material: Made of durable polyurethane (PU), which helps dampen vibration and minimize heat transfer. Comfortable Grip: Ergonomically designed mouse-shaped hand sanding tool with 3 finger notches for firm grip and optimal control while sanding, convenient for easy operation. Hook and Loop Design: The hook and loop feature allows for quick sanding disc changes, preventing the disc from shifting and rotating, and making it easy to remove the sanding disc without compromising overall strength. Wide Compatibility: The base securely attaches to any 5-inch (125mm) sanding disc, allowing you to use your orbital sander sanding disc or even discs that are damaged on the edges and unusable with an electric sander. Various Uses: Perfect for use with 5-inch sanding discs, sandpaper, abrasive sanding pads, and interface pads. Ideal for woodworking, hobbies, arts and crafts, auto body, workshop, and automotive applications.
