Walter 4.5-Inch Flexible Rubber Backing Pad with 5/8-11 Thread

Maximize Your Grinding Efficiency

For welders and fabricators, the quality of the finish is often determined by the stability of the abrasive. The Walter 15D144 Rubber Backing Pad (4-1/2" x 5/8-11) is a high-performance accessory designed to extract the maximum life and performance from your resin fiber discs. When grinding welds or blending surfaces, a rigid backing can cause the disc to bounce or chatter, leading to an inconsistent finish and operator discomfort. Walter has addressed this by utilizing a specialized rubber compound that offers the perfect balance of stiffness for aggressive stock removal and flexibility for smooth blending.

This backing pad is particularly effective when working on complex geometries. The superior flexibility allows the operator to manipulate the angle grinder to follow the natural curves of the workpiece, such as tanks, vessels, or automotive body panels. This "give" in the pad prevents the edge of the disc from digging in, which is a common cause of undercutting and rework. Furthermore, the rubber material is naturally resistant to the heat generated during heavy grinding applications. It dissipates heat effectively, helping to keep the abrasive disc cooler, which prevents glazing and extends the cutting life of the grain.

Safety and comfort are integral to the design of the 15D144. By absorbing the high-frequency vibrations generated by the interaction of the disc and the metal, it significantly reduces the strain on the user's wrists and arms. This ergonomic advantage allows for greater precision and control, especially during fine finishing tasks. The integrated 5/8"-11 metal thread ensures a secure and concentric attachment to the grinder spindle, minimizing run-out and ensuring safe operation at high RPMs. Upgrade your grinding setup with a backing pad that works as hard as you do.
