15M158 - Walter 7-Inch White Turbo Backing Pad for Resin Fiber Discs

Advanced Cooling Technology for High-Performance Grinding

The Walter 15M158 7-Inch Quick Change Turbo Pad represents a significant evolution in abrasive support systems. Designed by Walter Surface Technologies, this backing pad is engineered to address the primary cause of abrasive failure: heat. In high-speed grinding applications, friction generates intense temperatures that can soften the resin bond of fiber discs, leading to glazing, grain shedding, and drastically reduced consumable life. The 15M158 combats this through its exclusive "Turbo" design. The face of the pad features a distinct ribbed pattern that acts as a centrifugal fan when the angle grinder is in operation. This geometry forces a continuous stream of air between the backing pad and the abrasive disc, actively dissipating heat away from the grinding zone.

Structurally, the pad utilizes a saucer-shaped profile. This ergonomic contour serves two critical technical functions. First, it naturally orients the abrasive disc at the optimal angle of attack (typically between 15 and 30 degrees) for stock removal, ensuring that the operator maintains consistent contact without gouging the workpiece. Second, the saucer shape provides structural rigidity while allowing the necessary flex at the perimeter. The "White" color designation indicates the specific polymer formulation used, offering a balance of stiffness and flexibility suitable for a wide range of general-purpose grinding and blending tasks. It is neither too rigid for contoured work nor too soft for heavy stock removal.

This backing pad is specifically optimized for use with Walter's COOLCUT XX sanding discs, although it enhances the performance of most standard resin fiber discs. The "Quick Change" nomenclature refers to the ease with which discs can be mounted and removed, streamlining workflow in high-throughput industrial environments. By maintaining a cooler operating temperature, the 15M158 not only extends the life of the abrasive media but also protects the workpiece from heat discoloration and warping. It is an essential component for fabrication shops prioritizing efficiency and finish quality.
