Sander Backing Pad | 5 Inch 8-Hole Interface | For Polishing & Contours

This soft interface pad goes between your sander's backing pad and the sanding disc. It adds a cushion layer, which is important for working on curved or uneven items. This helps stop gouging and makes for a much smoother, more even finish, especially on delicate shapes. Features and Benefits - Soft foam build - Shapes itself to curves and irregular forms for even pressure. - Hook and loop surfaces - Grips your sanding discs firmly and attaches quickly to your sander. - 8-hole dust extraction pattern - Lines up with your sander's vacuum holes to keep your work area cleaner. - 5-inch standard diameter - Fits most common orbital sanders from brands like DeWalt, Bosch, and Makita. Applications - Sanding curved car panels before painting. - Fine finishing on wood projects with rounded edges or turnings. - Preparing boat hulls and other non-flat surfaces for sealing or coating. What It Is This Sander Backing Pad is a 5-inch diameter interface designed for use with sanders. It features an 8-hole configuration for efficient dust extraction and a hook and loop attachment type for quick disc changes. Made from plastic, its soft density allows it to conform to contours, making it suitable for a range of sanding and polishing tasks. It acts as the crucial link between your sanding machine and the abrasive disc. Key Uses & Applications This backing pad is ideal for polishing and working on contours. Its soft density makes it versatile for a variety of applications, including sanding metal, sanding wood, and even sanding car surfaces. When used with a random orbital sander, which moves in small, overlapping ellipses, it helps to minimise swirl marks. This type of sander, often called a random orbit sander, is excellent for achieving a smooth finish across diverse materials. How to Choose When selecting a backing pad, consider the pad diameter and hole count to ensure compatibility with your sander and abrasive discs. This 5-inch, 8-hole pad is designed for specific sander types. The soft density is crucial for polishing and feathering over curved surfaces. For general sanding tasks, a medium or firm density might be preferred, but for contour work and polishing, this soft interface is highly effective. Ensure your sander uses a hook and loop attachment system. Grit / Spec Guide The backing pad itself does not have a grit rating, but its performance is directly related to the abrasive discs used with it. For aggressive material removal on wood or metal, discs like an 80 grit are suitable. For finer finishing or preparing a surface for polishing, a 150 grit disc is often a good choice. When polishing, very fine grit discs are applied. The 8-hole configuration aids dust extraction, which is vital for a clean finish and extending disc life. Care & Safety Always ensure the backing pad is securely attached to your sander before use. Regularly inspect the hook and loop surface for wear; a worn surface can lead to discs detaching during operation. Keep the pad clean from dust and debris to maintain optimal adhesion. When using a random orbital sander, which is a dual-action tool providing both orbital and rotary motion, always wear appropriate eye and respiratory protection. Do not over-tighten the pad, as this can cause damage.
