07Q174 - Walter 7-Inch Quick-Step MG Backing Pad with Centering Pin

Industrial Grade Backing Pad for Quick-Step System

The Walter 07Q174 7" Quick-Step MG Backing Pad represents the core interface of the Quick-Step surface finishing system. Engineered for professional industrial environments, this backing pad is not merely a passive accessory but a critical component designed to maximize the performance of abrasive discs. The body of the pad is injection-molded from a specialized industrial-strength nylon. This material selection is deliberate, offering a high degree of thermal stability. Unlike standard plastic pads that may warp or become brittle under the intense heat generated during heavy grinding or polishing, the MG pad retains its structural integrity and necessary flexibility, ensuring consistent contact with the workpiece.

A defining technical feature of this model is the patented centering pin. In high-speed rotational applications, even a slight misalignment of the abrasive disc can lead to significant vibration, operator fatigue, and inconsistent finish quality. The centering pin physically guides the Quick-Step discs into the exact center of the pad, locking them in place relative to the axis of rotation. This results in a smoother operation and extends the life of both the abrasive and the power tool bearings.

The face of the pad utilizes a heavy-duty hook and loop (Velcro-style) mechanism. This system is optimized for high-torque applications, ensuring that the disc remains firmly attached during operation while allowing for removal in mere seconds when a grit change is required. This rapid changeover capability significantly reduces downtime in multi-step finishing processes. The pad is specifically calibrated for use on steel and stainless steel surfaces, providing the right amount of resistance to effectively drive surface conditioning discs without gouging.
