15D035 - Walter 4-Inch Flexible Backing Pad with 3/8-24 Thread

Engineered Support for Abrasive Applications

The Walter 15D035 4" Backing Pad is a critical accessory designed to optimize the performance of resin fiber sanding discs. Manufactured by Walter Surface Technologies, a leader in industrial abrasive solutions, this backing pad is engineered to provide the necessary support and flexibility required for demanding metalworking tasks. The unit features a standard 4-inch diameter, making it compatible with a wide range of commercially available sanding discs sized for smaller angle grinders and sanders.

At the core of this product is its construction from high-quality, impact-resistant plastic. In industrial environments, backing pads are subjected to significant mechanical stress, heat, and torque. Inferior materials can crack, warp, or degrade rapidly, leading to vibration and poor finish quality. The 15D035 is built to withstand these harsh conditions, maintaining its structural integrity over extended periods of use. This durability translates directly to cost savings by reducing the frequency of accessory replacements and downtime.

The pad is designed with a 3/8"-24 threaded arbor, a specific configuration used on many pneumatic and electric angle grinders. This ensures a secure, concentric fit that minimizes runout and vibration. Proper balance is essential not only for the quality of the surface finish but also for operator comfort and safety. Excessive vibration can lead to operator fatigue and potential long-term health issues, making the precision manufacturing of the Walter backing pad a significant advantage.

Flexibility is another key characteristic of the 15D035. While it provides a firm backing for aggressive stock removal, it retains enough pliability to conform to curved surfaces and contours. This balance between rigidity and flexibility allows operators to blend welds and finish surfaces smoothly without gouging the workpiece. Whether used in fabrication shops, automotive repair, or general maintenance, this backing pad ensures that the abrasive media performs at its peak efficiency.
