3M 7100089797 Rotor Blade Set Mini Orbital Sander

Product Description

The 3M 7100089797 is a replacement rotor blade set designed for use with the 3M 28737 Elite Series Mini Orbital Sander. Rotor blades are internal rotating components that drive the orbital sanding motion of the tool, and their condition directly affects sanding performance, surface finish quality, and tool longevity. When blades show wear, chipping, or imbalance, replacing them with an OEM-specification set restores the sander to proper operating tolerances. This set is the correct service part for technicians and tool repair professionals maintaining 3M pneumatic finishing equipment in auto body, woodworking, or surface prep applications.

This rotor blade set is suited for repair and maintenance of the 3M 28737 Elite Series Mini Orbital Sander. The mini orbital platform is commonly used in finishing and detail sanding work where a compact tool profile is required. Replacement of worn rotor blades is a standard service procedure performed during tool overhaul or when output speed or finish quality degrades. The set format ensures all blades are replaced together, maintaining balanced rotor assembly performance.
