15D042 - Walter 4.5-Inch Backing Pad for M14 Spindles

Precision Support for M14 Abrasive Systems

The Walter 15D042 4-1/2" Backing Pad is a specialized industrial accessory designed to bridge the gap between high-performance resin fiber discs and angle grinders equipped with M14 spindles. In the realm of surface finishing, the backing pad is often the unsung hero; it dictates the flexibility, aggressiveness, and life of the abrasive disc. This particular model is crafted from a premium, impact-resistant plastic compound that has been engineered to withstand the high torque and thermal stresses generated during aggressive grinding and sanding operations.

One of the critical technical advantages of this backing pad is its balance between rigidity and flexibility. While it provides the necessary stiffness to drive the abrasive grain into the workpiece for effective stock removal, it retains enough flexibility to conform to curved surfaces and contours. This reduces the risk of gouging the base material and ensures a more uniform finish. The M14 thread specification is particularly important for facility managers and operators utilizing equipment with European spindle standards, ensuring a safe and concentric fit that minimizes vibration.

Durability is central to the design of the 15D042. Inferior backing pads often suffer from heat embrittlement or stress cracking around the arbor hole. Walter has addressed this by utilizing materials that maintain their mechanical properties even under elevated temperatures. This ensures that the pad remains safe to use throughout its lifespan and provides consistent backing to the abrasive media, ultimately optimizing the cost-per-cut of your sanding consumables.
