04X202 - 2-Inch TWIST Medium Density Backing Pad with 1/4-Inch Mandrel

Technical Overview of the Walter 04X202 Backing Pad

The Walter 04X202 is a high-performance 2-inch backing pad designed specifically for the TWIST™ quick-change abrasive system. Engineered by Walter Surface Technologies, this accessory is manufactured from high-quality molded polyurethane. Unlike standard rubber pads, polyurethane offers superior resistance to heat buildup and mechanical stress, ensuring the pad maintains its shape and flexibility over a longer service life. The 'Medium' density classification, denoted by its orange color, provides a critical balance between rigidity and flexibility. This makes it the optimal choice for intermediate finishing steps where the abrasive needs to conform slightly to the workpiece surface to blend tool marks without sacrificing the firmness required for material removal.

Mechanically, the pad features a standard 1/4"-20 thread and comes equipped with a removable 1/4" shaft (mandrel). This universal shank size ensures compatibility with the vast majority of pneumatic die grinders and electric rotary tools found in industrial environments. The pad is rated for a maximum operating speed of 30,000 RPM, accommodating high-speed abrasive applications on materials ranging from aluminum to stainless steel. The surface design of the pad is engineered to provide uniform support across the entire face of the abrasive disc, promoting even wear and consistent finish quality. The TWIST™ locking mechanism ensures a secure connection that will not slip under torque, yet releases instantly with a simple quarter-turn.

For MRO and industrial supply procurement, this SKU represents a durable, reusable component that maximizes the efficiency of consumable abrasive discs. Its robust construction reduces the frequency of replacement for the backing pad itself, while its design characteristics improve the lifespan of the attached abrasive media by preventing overheating and uneven pressure distribution.
