48M729 - Walter 7-Inch Turbo Backing Pad for Fiber Discs

Maximize Abrasive Performance with Walter Engineering

The Walter 48M729 Supporting Plate is a high-performance industrial backing pad designed to extract the maximum utility and lifespan from 7-inch resin fiber discs. In the realm of metal fabrication and MRO (Maintenance, Repair, and Operations), the efficiency of material removal is often dictated not just by the abrasive media itself, but by the support system driving it. Walter Surface Technologies has engineered this "Turbo" style backing pad to address the two most common issues in heavy grinding: heat generation and lack of aggression.

Constructed from a proprietary high-impact plastic, the 48M729 offers superior rigidity compared to standard rubber pads. This rigidity is crucial for transferring the torque of the angle grinder directly to the workpiece, allowing for higher contact pressure and faster stock removal. The defining feature of this model is its ribbed surface profile. These raised ribs serve a dual purpose. Mechanically, they create localized pressure points behind the abrasive disc, which increases the "bite" of the grain into the metal, significantly speeding up weld removal and beveling tasks.

Thermally, the ribbed design acts as an impeller, generating airflow between the pad and the disc. This induced air circulation helps dissipate the intense heat generated during friction, preventing the abrasive grains from glazing over and the workpiece from discoloring due to thermal shock. By keeping the assembly cooler, the 48M729 extends the usable life of each fiber disc, resulting in lower consumable costs and reduced downtime for disc changes. This backing pad comes complete with a matching clamping nut and features a standard 5/8"-11 thread, ensuring compatibility with the vast majority of industrial 7-inch angle grinders used in North American facilities.

Key Industrial Benefits

• Thermal Management: Air-cooled design reduces the risk of warping thin metals.
• Cost Efficiency: Extends the life of resin fiber discs by preventing premature failure.
• Durability: Resistant to cracking and deformation under heavy load.
