Mirka 8292557031 Backup Pad 5.3" M4 Grip Soft

The Mirka 8292557031 is a 5.3-inch soft backup pad designed for use with Mirka's hook-and-loop sanding discs. This backup pad features the M4 thread connection, making it compatible with Mirka random orbital sanders and other tools using the standard M4 mounting system.

Key Features:

• 5.3-inch (135mm) diameter for versatile sanding applications
• Soft density foam construction for conformability on contoured surfaces
• M4 thread mounting for secure attachment to compatible sanders
• Hook-and-loop (Grip) interface for quick disc changes
• Ideal for finish sanding and working on curved or irregular surfaces
• Provides excellent cushioning to prevent gouging or aggressive cutting

The soft foam construction of this backup pad allows it to flex and conform to surface contours, making it an excellent choice for automotive bodywork, furniture refinishing, and other applications where surface conformity is important. The grip surface ensures abrasive discs stay firmly in place during use while allowing for fast, tool-free disc changes.
