Key Features & Standards

• Rigid Plastic Support: Durable molded body provides firm backing to prevent fiber sanding discs from tearing or flexing excessively under pressure.

• M14 x 2.0 Metal Insert: Threaded steel/brass center nut ensures a secure, wobble-free connection to standard rotary spindle shafts.

• Contoured Beveled Edge: Smooth outer edge contour allows even blending and prevents digging into the workpiece during angled sanding.

• Versatile Compatibility: Ideal for automotive bodywork, metal rust removal, weld smoothing, and stone/marble polishing.

⚠️ Safety Warning: Ensure the backing pad is securely tightened onto the spindle shaft before operating power tools. Never exceed the maximum RPM rating of the backing pad or attached abrasive disc. Always wear ANSI-approved face shields, safety glasses, work gloves, and dust protection during grinding and sanding operations.
